    Old to W body's, new to this forum

    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!

    New here with a 03 Monte Carlo SS

    Hey everyone, My name’s Ryan, I’m from Long Island, NY, and I’m new to the Monte Carlo platform. I recently picked up a 2003 Monte Carlo SS and I’m excited to finally start a build thread and be part of the community. By trade I’m a licensed marine engineer, so I’m very hands-on mechanically and enjoy learning the technical side of things. On the automotive side, I’ve worked on and tuned a variety of platforms, everything from basic bolt-ons and wiring to full tuning using HP Tuners, Hondata, and standalone setups. I enjoy both the mechanical and tuning sides of builds and documenting the process. For the Monte, the plan is to start simple, catch up on maintenance, fix worn components, and do some basic bolt-ons while I sort out the body and cosmetics. Once the chassis and body are in better shape, the goal is to turn things up. I’m currently torn between a Gen V M90 top swap or going turbo, but either way the end goal is a "reliable", fun street car that still rips when you get into it. I’ll be sharing progress, asking questions, and learning as I go. Looking forward to seeing everyone’s builds and being part of the community.

    OIL LEAK - 1994 Cutlass LQ1

    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!

    Firmest front springs for a first gen?

    Automatic equipped FE3 springs from a 3.4 DOHC car seem to be the stiffest. The manual trans springs are slightly less stiff (as compared side by side, and they have different part numbers). In other words your automatic Z34 has the stiffest ever available factory.

    I know it's been done before. I think the biggest issue is always switching the vehicle over to OBDII. But if you aren't going for a Series II L67 a Series I L67 from a Bonneville that is OBD 1.5 might make a better option.

    OIL LEAK - 1994 Cutlass LQ1

    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.

    OIL LEAK - 1994 Cutlass LQ1

    UPDATE - I believe I may have found a shop with a mechanic having the experience to have worked on these motors that will do the job. My first hunch was to go to a Chevy dealership as the Lumina had these motors as well, those Z-34's you almost never see (?). As soon as they found out I was in no rush to get the car back, they were more open to the idea of working on it. I guess they thought I wanted it done yesterday. Not the case, anytime between now and July 22 will do........ Stay tuned

    OIL LEAK - 1994 Cutlass LQ1

    Wow, you've almost had that car as long as I've had my 89 Cutlass! Can't remember if I got mine in late 93 or early 94. Yes, that seal goes bad in all of them. Not if, but when. Rear main seal is rare. Oil pump drive O-rings going bad I'd say is 100% rate. If you were going to DIY it, I'd say don't worry about pulling the rear head. I owned my 94 for 12-years and my fudge-fix lasted for most of that time up to the day I sold the car. If you're having a shop do it, I imagine the intake manifold R&R itself isn't cheap, so I can understand wanting to do the head gaskets at the same time so as not to have to pay for a repeat job in the future. However, head gaskets on a DOHC V-engine sounds like it could be quite expensive labor-wise.

    OIL LEAK - 1994 Cutlass LQ1

    I've ground the top ridge of the pump drive down slightly to allow for more room to work, then use a distributer gasket for a Lumina van with a 3.1, just give it a cut and slather it in RTV, seems to work well. and I'll be damned if I'm pulling a head just for that.

    OIL LEAK - 1994 Cutlass LQ1

    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.

    1992 Cutlass Supreme Coupe Door Speakers

    I bought some decades ago to do the same thing, but never got around to it. I was going to try to mod them for 6.5" speakers and needed a plan for how to mod the buckets, but in the modern day, it would make more sense to 3D print some custom ones rather than mod the OEM ones as I wanted to use the OEM grilles which are flat against the trim panel. I can't find them at the moment or I'd snap a pic. As for prewired, my 89 wasn't prewired, but different years might do things differently.

    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.

    Spring shops can only install what's available in the aftermarket, & FE3's are not one of them. The springs availability is *generalized*, only the basic spring would be available.

    There are no longer aftermarket *performance* springs manufactured for the 1st gen W's, if you've got the FE3 suspension under the car then you've already got the stiffest springs available. I take it that you want lower the front to match the dropped rear's ride height?

    They're supposed to retract. They don't "fully" retract in the sense you no longer see them, but they're supposed to retract nearly all of the way. When I had my 92 Cutlass many years back, the sunroof didn't move properly. I believe the drive gear was stripped, and I ended up just pulling an entire sunroof unit from a car in the junkyard and replacing it. I also had the sunroof in my 2000 Regal break, to where it wouldn't retract properly, and would only tilt. I never looked into fixing it...but it acted similar to a power window with a broken track.

    L67 swap A/C

    I'm going to differ with you on this Kyle....... what OP needs is the necessary A/C piping from a 1st Gen Regal with the 3.8 engine. If you intend on keeping as much as your car is currently fitted with you'll need the a/c compressor manifold hose assembly that was fitted to the 3.8 Regal & a new rebuilt pre 94 compressor. Everything prior to 94 is R12 based, everything post 93 is R134 based. When GM introduced 134 in 94 they changed ALL of the A/C line fittings thread pitch so NOTHING from prior & post can be used together. My suggestion to you is to keep your 92 car all 92, get that old 92 3.8 manifold hose assembly & purchase a new *rebuilt* pre 94 A/C compressor, even the manifold hose assembly changed in 94 because GM redesigned the back end of the compressor housing for 94 so the old manifold hose will not attach to the newer design compressor housing. Purchase yourself a new receiver/dryer as well as a new orifice tube. Go into Rockauto, search 92 Regal, they still house most of what you'll need.

    It’s been just a little over a year now since I got the Regal…so what better way to celebrate that than with some more recent pictures. Nothing much visually has changed except for the refinished wheels and new tires…which was a fairly large, yet subtle change on its own. My intent is to keep the car as stock as possible, and to keep it up to snuff mechanically to be used as a reliable, fair weather cruiser. And to shake things up…. This is the final picture I ever took of my 89 GS before it was parked for good in summer of 2008.

    tuning for 92 lq1 turbo

    You should be able to OBD2 swap if you want to go that route, but I'm not sure how possible tuning is with the current options besides what GTP091 mentioned. DHP can still be obtained, but support isn't what it used to be. redzmonte had a turbo 3.4 95 Monte that he swapped the OBD1.5 to OBD2 and tuned. I had tuned my 96 3.4 GP with DHP years ago. I believe you can run a 97 PCM and use HPT, who supports 97+ 3.4 Montes, so I'm not sure how that would work. edit: after some research, looks like you can buy the DHP interface from the original manufacturer (AVT) and it SHOULD work. Setting up DHP on a Windows 10 laptop is a bit of a chore. http://www.avt-hq.com/852_hw.htm http://www.avt-hq.com/price.htm

    3400

    any '96-03 3400 will drop right in with the 1st gen OBD2 harness. You will have the easiest time with a '97 system (harness and PCM), I'd go with that. A '96 system would work as well (though it's less tunable should you go that route), but with either setup you go with, grab a PCM from a '96-97 Venture/Montana/Silhouette.

    3400

    you will need: -throttle cable and bracket -upper rad hose -coil bracket and module -front pass. side engine mount bracket -ac compressor (not sure if the orginal one will work) -power steering pump and H/P line -brake booster hose all from a 3100/3400 w-body You can get away with running it on the stock ECM as long as you use the stock fuel injectors and injector harness from the 3.1. You will need to change (or have one made up) front pipe/ down pipe to hook up to the rear 3400 exhaust manifold. A 3 wire coolant temp sensor and connector from a 92+ 2.2L Cavalier is the easy way of hooking up your temp guage wire from the rear head on the 3.1\ you will also need a lower rad hose for a 92-93 3.1L w-body The wiring from the coils gets re-routed to the rear of the engine from the front... then its little things like coolant hoses, and vac lines. That is all that I can think needs done right now, but I am sure I am missing a few things.

    3.1 to a 3.4 i want power?

    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.
