Well I cant wait any longer for you guys. 23.5 years is a bit long to make a guy hang on. So I just went ahead and got it myself.

Good day, I have been a W body enthusiast since high school 04. In my student parking lot, we had a 93 Gran prix, 94 olds cutlass supreme, 94 cavalier z24, 95 monte, and my lumina z34. These cars were everywhere! My first car was a 94 lumina z34 (still have it). In 2012 I put a 4.9 PFI in it and it is almost complete. I just need to replace the rear suspension and odds and ends. I have a 99 Monte (needs some work), and I just picked up a decent (needs some work) Cutlass supreme. I am buying a new top for the cutlass on Friday. I want to get black canvass instead of the white (the car has black leather interior). They come in black, grey, white, red. What do you all think would be the best color? Just curious. Very few of these ole buggies still around (at least in my area). I thought I would join the forum to see what you all are up to (I feel very late to the party). I already have seen some super nice examples of these cars (nice job everyone!). Ill post more as spring hits and I can get them out, and work on them more. Also, not adverse to loading them up on the trailer for any meets that might happen. Thank you! Hope you all have a wonderful day!

Welcome! I think black top will look great on it. Better late than never! Not as bustling as it was back in the day, but there's a few of us W-body old timers left. I wouldn't mind seeing pics of the 4.9L in a W-body.

anyways, welcome to the site.

Wow, that's awesome!

UPDATE: the car is going to the mechanic on 2/23 for this job. It will be going to a chevy dealer whose mechanic has decades of experience which is exactly what I was looking for. This mechanic is semi-retired and picks & chooses the jobs he wants to do. When he learned I'm the original and 4th owner he took the job. I was asked to supply all the parts which I think I will need. Included with these parts will be a new EGR valve and a new Low Coolant Sensor (due to the coolant being partially drained). I made a copy of Gnat's photo so thanks again for this. I will be seeing how the mechanic feels about just going the RTV route in lieu of pulling the rear head. Not only will the job be alot cheaper, I'd really prefer not opening that Pandora's box of potential additional issues if the head needs to be taken off.

Damn, that's a rare one!

Thanks all for this. As of the moment the car is in storage do it will be a while before I can check it out, but I will say I get more & more confident this will be the cause. It has been happening for a long time. Form the day I bought this car in Oct., 1994, I always wondered where a quart of oil was going every 1000 miles or so. My money is on this as pictured above, it was probably badly sealed to begin with. And these things don't get better, only worse. I went in and checked my 2020 repair bills from when I had the intake manifold gaskets replaced. The mechanic also replaced the gasket for the part 10130955 as you see in the photo but no mention is made on whether the distributor plug seal was addressed so I am going to assume it was not. While it's a shame all that work that was done to the motor back then would have to be re-done just to get at what needs to be repaired, so be it. Even if I decide to get the rear head pulled to replace the O-ring rather than trying my luck with sealant, that's still way better than having the entire motor pulled. I might as well go the whole 9 yards and have both head gaskets replaced for a one and done job. I should be getting the car out of storage within the next few weeks, I'll keep all posted on how things progress, and thanks again, much appreciated!

You're in the right place because we love our W-bodies here. Welcome!

The thought here was that you don't drive your W's in the winter.

Got the fuel line disconnected and fuel can ready to go but no go on the fuel pump. Do I have it wrong here? The car has been sitting for 6 weeks so the battery may be weak but radio turns on. Edit nevermind I'm an idiot i see the number on bottom of relay and i had it wrong Works like a charm thanks all

I wanna see pictures of the Gran Prix, never seen one before! /s Welcome!

Does the pump run? If it does, unhook a fuel line under the hood and jump the fuel pump relay.

It's that time. The oil leak in the rear main seal of my 1994 Cutlass Supreme SL with the 3.4L motor has gotten so bad that it needs to come out for repairs. In addition to this being in need of replacement, I am going to have the oil pan gasket replaced as well, along with the 3 coils and the alternator while the motor is out of the car. In addition to that, is there anything else anyone can think of that should be replaced while the motor is out, as this would be a golden opportunity to get it done. The engine compartment will also be degreased to clean up the big mess this leak has been making. It does not need a timing belt, water pump, or any intake manifold work as this was all done 5 years and 10,000 miles ago and no issues here.

UPDATE: I was just advised the mechanic is going to elect to go the RTV route; the head will not be pulled for this job. I think you can all hear the huge yell of relief coming from this desk. I'll be sure to post once completed.

I feel like it was a red 4-door. No real reason, just a feeling.

That's how I'm looking at it. I wouldn't have not bought the Regal, or insisted on paying any less for it if there was a disconnected and neatly stored amp wire running back to the trunk, everything else being equal. My thought is that the target buyer for that car is the type of person to be a member here, and is likely to be relatively well versed in them to where something like that wouldn't make a difference in either case. It's not a super low mileage museum piece where I feel something like that would make a difference. If anything, that car being "The Car" of these forums makes it more desirable, but that's just me.

Agree. As I always say, your car, your call. Do it for what you want rather than what the next owner may (or may not) want. I myself am after the total factory look, but if I can hide something that will otherwise give it the factory look, that's good news. I've replaced my Retrosound rear speakers with another aftermarket brand set that fits into the hole and under the grille sufficiently. They get hit by the sun with that huge rear window so I avoided a paper coned speaker with something more durable. I'm loathing replacing the door panel speakers, but as soon as II find that set of correct NOS ones I've got in storage somewhere, I've got a job to do............

Unfortunately its the opposite of that pre-conceived notion of the south, they spread that stuff anytime the temp gets close to 32F overnight and its wet out. Ive researched a bit more into the options available and will go with the coated PowerStop kit from RA. Just trying to generate some conversation I guess...

I'm somewhat surprised that where you are in Tennessee that you have to even concern yourself about this. Now if you lived up here.......well, that's a different matter.

Not on my W's...but I use them on my dailies. I prefer to use the rotors with the black coated hat/edge vs the silver coated ones, as I find they hold up better. They seem to hold up relatively well, even throughout the winter. In all honesty though, if your current rotors are still good you could always hit them with a bit of black spray paint. I quickly hit the rear drums of my truck over 5 years ago without any real prep work, and those have held up better than some of the coated rotors i've run.

My grandparents had a 04 Regal GS with a "supercharged" emblem on the trunk lid. If I recall it was on the driver side.

Check Amazon. Just search Buick logo door light. Some are stick on with double sided tape and a magnet style sensor to activate them one the door opens.

GM if you can get them, anchor would be last resort. I just ordered a complete set of DEA mounts a couple days ago ago for my Lumina.

I was able to replace the o-ring and add an extra gasket with the information from the old double gasket thread all without removing the rear head. I also put RTV on it and it never leaked in the 10+ years I owned the car after the repair.

One should have the service manual within reach for electrical diagnosis.

You are correct on that point, I will be checking my local independent shops to see if they want the job. Not everyone wants to work on these. The first thing I will hear is the job would cost more than the car is worth. I bought this car new in 1994. I gave it to my dad in 2012 who in turn sold it to my brother in 2018. My brother did a swell job of running it into the ground, but when my dad passed away 1/2020 my brother didn't want the car anymore and showed up at my house a month or so later and handed me the keys. That makes me the 1st and 4th owner. There is no mechanic on this earth that's going to be successful in convincing me that any job needed to be done on this car will exceed its value. I watched a 24 minute video earlier today on how to do this job. II won't be doing it as a result of watching it. These videos are valuable in that respect as well.

It's in the valley right by where the transmission and engine block are joined together. Oil will pool around the distributor plug (also called "oil pump drive") and run down the side right where the transmission mates to the block so where it drips on the ground looks very much like a rear main seal. An O-ring goes bad on it allowing it to leak. Shine a flashlight down there, and if there's oil pooled in that area, that's your culprit. Unfortunately, yes, it's blocked by the rear head. What most people do is lift it up as high as possible and clean it and the block as well as possible. Some sandwich a thin O-ring under it, others RTV it. My memory is hazy, but I think I may have done both. On my pic, high pressure oil-resistant RTV is the stuff kind of squishing out from under it. It's dirty because this was many years later, but it worked great. Official GM procedure is to pull the rear head, but that's way, way too much trouble.

I think the mounts will fit the doors, but I don't know that they'll fit under the door panels. 95-96 used 5.25" in these angled enclosure pod things that stick out quite a bit while 88-92 used 4x6's on a flat plate.

So my hunt begins for an intrigue with the 3.5, I'm looking specifically for a GL or GLS with the 3.29 gear ratio. Anyone know the RPO code for that to help me in my searches? Google and rpocode.com aren't helping me

There are various designs...plastic or steel.......seeing as you don't intend on getting into this sort of repair again I'd suggest just picking up the plastic set, you should be able to find them at Harbor Freight. The inlet (pressure side) is 3/8 as for a gas can..really up to you..pick up a pair of containers that will hold a total of 15 gals?

This is the only device that will separate the fuel line from the rail.... there is another method you might try.... raise the car up high enough to get under comfortably & disconnect the fuel filter from the fuel line (one end of the filter makes used of threaded connection , the other end is the same ac/fuel line quick disconnect slip-on connection). Once again run a length of hose long enough to clear the car & fill a gas container to drain the tank.

87 to 30

The *actuator* was discontinued approx 20 years ago.......finding an NOS piece would be a challenge. The item IS serviceable..........

"Automatic shoulder belts"

That is interesting how the sun visors disintegrated but yet the headliner was ok. My armrests are still soft and pliable, I just had to really clean them due to the years of elbows and forearms constantly touching them. They were pretty dark and black. I used a gentle mixture of Dawn soap and warm water and just gently rubbed them with a lint free cloth until the red started to appear. My headliner and sun visors are perfect in this car thankfully. The STE...not so much. The California desert pretty much baked it's interior. I'm SO THANKFUL that the International has such a nice interior. It's part of the reason why it's a 1 of 1 car. I'm actually restoring the front seats in it right now. The side bolster on the driver's seat is worn out. I'll post pics soon. I have all the hard pieces figured out and collected on the STE. It will be pricey though but I'll do a little at a time. The rear seat headrests and upper top portion of the seat will need to be reupholstered. The front seats are in great condition and just need to be deep cleaned. Same goes for the carpet. Got a new dash pad and found some really nice door panels with perfect door panels. I posted in my thread about all these parts being found. The biggest win was finding a perfect set of door speaker grills and the lenses for the door lamps. Took me years to find those! The original door armrests and the ones I pulled from a junkyard STE...again, not sticky or gooey at all. Pliable and very nice with no cracking or discoloration. I really lucked out there.

Like the title says, I am a new member now, but I was a fairly regular member here around 15-20 years ago. My screen name at that time was Regal_GS_1989. I originally owned an 89 Regal GS coupe, a 92 Cutlass International Coupe, and finally a 2000 Regal Sedan. Life got busy, I stopped posting regularly, and the 2000 was sold off about 10 years ago for something newer and more family friendly. Time has marched on, and I am now in a position where I have the time and resources to be able to own a “weekend” vehicle. As luck, or possibly fate would have it, this beauty quite literally fell into my lap at the perfect moment… A 92 Regal GS Coupe. Black, Grey leather interior, low milage, One owner, garage kept its entire life, ordered new with every option box checked off…save for the sunroof. It’s truly worthy of the term survivor, and it’s exactly how I would have ordered one myself back in the day. Gotta say…it feels sort of strange to be back here posting again about a 1st gen coupe…but I can get used to that I am also surprised at how many screen names I still recognize as well!

Factory all the way for me. But I did upgrade to CD from cassette, a factory correct unit, in my 94 CS

If you use your resources correctly, you can get a 3800 for the same price as the 3400. The smart thing would be to look for an S3 and then get an S2 UIM to make it all work. Anyways, the flywheel between the engines are the same. Both used the same 4T65-E trans. The motor mounts should be the same as well. My understanding is that the blocks are the same but the internals are what differentiate them from a 3.1 liter and a 3.4 liter.

Use the trans that is in the 88 and the ecm from the 2.8 as well. If the 95 doesn't have the coolant temp sensor for the Guage/light in the rear head you will have to install a 3 wire temp sensor where the 2 wire is. The throttle cable from the 95 is needed as well. If your '88 has a 3spd you will have to rig up a kick down cable linkage on the throttle body some how. I welded a bracket to the throttle body myself, wasn't perfect but it made it drivable. Sure there may be some other things that I'm missing since it has been about 6 years since I swapped my old lumina!

on to the wiring this will cover all 97-99 monte/luminas(possibly cutlass too but im not sure) on the c100 plug switch the b1 and d5 wire. literally cut both and switch positions. i also cut and taped off c1 as its unused. will post 2000 lumina and 97 and 98 monte c100 pinouts tomoro mebbe nitehawk or someone else with a3800 swapped 96 monte will post that second part of wiring theres a plug on the d side that plugs into the harness on the fender for the wipers stock has a 6 pin plug, 2000-01 is a 3 pin. cut the female end off ur original harness and the male? end off the donor car with a few inches on each plug. simply match colors splice and b VERY liberal with the electrical tape. voila you just made ur adapter harness for wipers. if ur gonna 3800 swap later this adapter will work for that too will post pics of my adapter and location tomoro also

Welcome to the site - are you thinking of an entire engine swap or just the top end swap? I won't have any answers for you on that but in reading your post I wasn't completely clear. As for the rear suspension, I've been looking into this matter myself recently. Everything on my car related to rear suspension and brakes is rusted beyond recognition (but somehow the body is totally solid!). These two writeups have been Very helpful to me as I've been feeling my way through what my next steps should be... converting to rear coilovers: http://www.w-body.com/showthread.php/37622-Coilovers-Adj-Mounts-Solid-Cradle-Bushings-UPDATE-3-25-Design-Done%21%21%21%21?p=651227&viewfull=1#post651227 and swapping in aluminum knuckles and bigger brakes: http://www.w-body.com/showthread.php/46209-Bob-and-Rob-s-Gen-2-Aluminum-Rear-Knuckle-and-Brake-Upgrade-How-To-with-Pics

get it tuned and at a minimum, adjust the TV cable so it shifts later, the LA1 makes more power past 4700, think more along the lines of a 6000 RPM shift. better yet would be to replace the th125C with a 4T60-e

the last 2 3400 swaps I did used 3.1 injectors on stock obd1 ecm's and they both run fine. the bigger injectors will make more power with a tune, but the first thing I would do is start with a better fuel pump. when I first put the 3100 in my old 84 cavalier I went to the track then swapped to a Camaro LT1 fuel pump and went back the next weekend with no other changes an dropped almost 4 tenths off my ET. if I was doing a basic (stock) 3400 swap on a obd1 car I would use 96-99 3400 or 3100 injectors with matching fuel rail (2000+ injectors will not work on stock ecm) or 2.8/3.1 injectors with a 2000+ 3400 fuel rail that has the higer pressure regulator. But if I was mooding a 3400 and dropping it in I would use injectors sized for the fuel requirements of the engine and a full tune.

keep it simple and just bolt in the 3400 its less power than the TDC but less weight too! I would just use the stock tranny to keep cost down. you will need the front pass. side block mount from a 3100 equipped w-body because the bolt holes are in different spots, at least just on that spot of the block. use a coolant temp sensor from the 3400 (3-wire ) and wire up the temp guage to it insead of the back head cause the 3400 has no hole for the sensor. you will also need a throttle cable and exhaust manifolds for a 3100 w-body. Most people use the 3.1 injectors and harness when they do the swap untill they go to tune it. stay away from the '04+ 3400's in the equinox (I beleave it is) they have a plenum that faces the opposite way and a different crank sensor pick up on the crank that will not work with your 3.1 ecm. that is all that is comming to mind right now.

I was the one doing that swap, and if you're going to run a 3400 it's definitely worth it. You don't want puddle fuel injection on a 3400. The hardest part in your case would be repinning the C100 connector to your car's pinouts. Also, if you plan to use the same tranny you have now, that will require doing wiring changes on the harness, or you can just use the tranny for the 3400, and you're set. There really wouldn't be much more beyond that. Mine was a PITA because I had to convince my ECM that it's controlling a tranny when it is in reality a 5 speed.

I would probably keep it as-is just for the novelty of it! A Quad4 W-body is rare enough, a Quad4 5-speed is extremely rare!

well I know tom wants a 5spd...and i have basically the same exterior package.

OMG tom lets buy that car....since I could use it for a parts car
