    Another red 90 TGP

    I just picked this one up last weekend. I had it loaded and down the road when I stopped for fuel and then decided to look it over, lol. I was floored when I saw the mileage! The car had all the paperwork from its yearly inspections in the glovebox, confirming the mileage right up until 2008 when it was parked. I'm assuming it was the brakes that did it in. I originally purchased it for parts and the front valance and interior bits were what I was after, but now I believe she will be back on the road soon. Everything inside works like new, the switches feel crisp and positive as they should, all lights, sounds, gauges etc function. The car will fire and run for just a few seconds, so I've pulled the injectors and will drop the tank for a complete fuel system clean and put in a new pump and filter. I'll have my body shop guys pull and fix the quarter panel dent, buff her out as good as possible and see how well she looks. If it was a sunroof car, I would most likely keep it, but since it isn't, it'll be looking for a new home in a few months. Now, if I could only find a dang black car!!

    Front suspension fail

    She's back on the road! After a long winter of fighting rusty bolts, I finally got her back together yesterday. I carefully drove her around the block once, and she seemed to drive and shift fine. I haven't noticed any leaks from the transmission or the brake lines. I'll try a longer drive tonight after work and see how it goes. Parts replaced: Passenger side only: Axle. Both sides: Control arms, tie rods (inner and outer), ball joints, flex brake lines. Parts saved: Fender (I straightened the bent lip). Wheel well trim and lower cladding were slightly damaged but I reinstalled them. TBD: Passenger front tire and hub. The tire held air all winter, but I need to drive at higher speeds and go around corners to evaluate the hub and tire. Total cost: About $400 including tools. Time spent: I don't want to think about it, probably 50+ hours if you count watching videos and buying tools. It doesn't sound like much, but I found ways to make the project take forever. It was my first time doing any of these jobs on any car, so it was a slow learning curve to figure out what technique to use. I often would only have two or three hours a week to work on it, so it dragged on and on. I tried to save money by using the wrong tool for the job a few times, which just ended up with wasted time and frustration until I would give up and drive to the store and buy the right tool. Once I had the right tool and the right technique, each job wasn't bad. Moral of the story: Buy the right tool!

    Hi folks, I joined this forum at the suggestion of a guy on another forum regarding a '96 Grand Prix SE (150k miles) that I'm trying to fix up. I bought this car for peanuts knowing it had a bad head gasket (or worse.) With a cold engine and radiator cap removed, coolant shoots out of the radiator whenever the starter is engaged or engine running. There's evidence of coolant boilover out of the coolant expansion tank, plus coolant in two or more cylinders (wet plugs). Also have coolant in oil (not a huge amount, but enough to tell it's there). Idiot previous owner wired up the radiator fan to run all the time instead of fixing what was probably a simple intake gasket, and proceeded to overheat the piss out of it. I'm pretty confident it's head gasket and not just the intake gasket. Oddly a compression test gives me 170 PSI on all cylinders. Pretty major power steering leak and a small section of rotting brake line that needs replaced round out the list of problems with this car. Shouldn't be all that difficult to make a good runner out of this, I've done head gaskets and fairly major repairs on other vehicles. I will probably make another post inquiring about options for repair-- I'd really like to consider an engine swap. This is purely a project car, can take my time and do it right. But for now, just wanted to introduce myself and add a couple pics of the car. Have always loved this body style GP, didn't give it a second thought when I saw this for sale, I had to have it!

    New to the site!

    Big thanks to Jay! He grabbed me these LQ1 motor pieces that I need for the STE. They will make a big difference in the appearance and correctness of it's engine bay. Also, he grabbed me an extra cam cover and these little booklets. They have awesome information regarding our W's including torque specs. I've never seen them before or even heard of them so I think they are kinda rare, maybe not, but I am so thankful he grabbed this stuff for me. I really needed this little spark plug holder for the front wires as my STE's is missing I think and the wires are just thrown everywhere. I also put in my spare cluster and the rest of the dash/HUD so that I can watch her vitals when I first start her up in over 10 years of not running!

    Back Again

    Hello all, I was a member here in 2000-2004ish (FATGUY) and life happened. Back then I had a Maroon 1990 Turbo STE and was fairly active. Since then (read as kids, wife, jobs, moves) the car went away and eventually I bought a 1995 Cutlass Supreme body and dropped in a 2002 3100 for my daily driver about 90 miles per day. 5 1/2 years and 120,000 miles later I had an engine mishap and now and contemplating what direction to go with the car. My wife hates it, I LOVE it!! lt is starting to show its Upper Midwest Salty Highway wear, but its not too bad yet (neglected the last couple of years). I am currently looking for a few parts to fix it back up and will be here more often with updates. I am extremely busy with 3 teenagers, work, restoring a 1973 Nova for a friend, and general honey-do list items, but will get here when I can. Good luck to all maccdadd_72

    PPG Turbo Grand Prix Pace Car

    Hi, I am researching all of the PPG Pace cars and came across this forum while looking for any info on the 1989 Turbo Grand Prix. I was also the guy who owned the yellow wheels posted above - small world huh? Let's start with those... They are 16" BBS RSII wheels, custom painted. The tires were Goodyear Eagle VR50 with shaved tread. As far as I know, PPG kept more than one set of mounted wheels/tires on hand for each pace car. I purchased a few sets of wheels from the auction they had at their warehouse in Strongsville, OH. I know for sure one of the Mustang's wheels I purchased is in Jack Roush's museum with another set of the same custom wheels. So the Pontiac may be alive and well, despite these wheels being sold separately. I put the yellow BBS on a 1994 GTP but ended up selling them. (20 years later, I wish I hadn't now.) My dad worked for PPG, so I got to go to some Indy races as a kid/young teenager and see many of the PPG Pace Cars in person. I've always had an interest in the Pace Cars and have been gathering images of them over the last decade. There's about 100 different pace cars! I don't have any additional information on the 1989 Grand Prix, but do have one photo that you guys haven't posted. I'm in the process of adding this car to an online catalog of all PPG Pace Cars that I finally got around to starting this winter, I originally thought that most cars were destroyed, but while building this site I found that quite a few made it into the hands of private collectors. There are also a good amount in museums. Only a small portion have been confirmed to have been destroyed.... so there's hope for the Pontiac.

    Your oil pump failed? I'm not sure I've ever even heard of an oil pump failure on a 2.8/3.1. Anyway, you should still be able to get Melling pumps made in the USA.

    I do love fins, chrome and horse power just like everybody else, I have also put my foot down to other car collectors about my taste, but when I roll up in my car from 1990 among a sea of 69 Camaros and tri fives Chevys I stand out. We have the cars that were not suppose to survive but THEY DID! So make room, like it or not. I do understand that the majority of people grew up around the rear wheel drive big v8 cars but the FWD drive cars can pack a punch to.

    Be double sure to check the Sub Frame mounts,,, REAL GOOD!!! On My 93Z34 the mounts appeared to be in good shape,,, on the outside... However when I removed them they were trash,,, rusted and in pieces on the inside... I was battling weird steering issues for years!!! Sometimes it would pull to one side or the other under acceleration or braking... When I did my engine swap I got new ones because I wanted to replace anything that could wear out on the car... Wheel bearings,,, Engine/tranny mounts and any other mounts and basically anything that could cause trouble... Fixed the steering issues!!! Good luck,,, Tom B...

    It destroys the paint underneath. There's a reason everyone stopped using them in the 90s.

    When you do the brake swap could you take a few pictures and do a little write-up of sorts? That would be a really interesting thread...

    They just get torqued down. There is no adjustment. Put both the rockers and the pushrods back in the exact same places they came out of (the 60 degrees use two different length pushrods). Do you need to replace the intake gaskets because they're leaking? 50k miles is pretty low to have those gaskets leak, especially on a Gen 2 motor, which don't really tend to have issues.

    LQ1 Timing belt

    You *should* be good. It's technically non interference, but its not completely unheard of to bend valves. If it was a low-mid RPM you are probably good. I had the same thing happen ages ago and I was fine. I've done this job many times now, its not as bad as it seems but it is rather time consuming. For a 93 you will NEED, at minimum: Valve cover gasket set, intake gasket set, Timing belt, all 3 idler pulleys. You'll need at minimum tool wise the cam sprocket removal tool, the cam cog holder tool and either the cam hold down tools or some flat stock with a hole drilled in it to lock the cams in position. Now the kick in the nuts. The actual timing belt tensioner actuator is getting difficult to find now. It's a GM dealer item only and I don't know if its still in production. If the spring inside that broke you'll need a new one. If its still good it can be reused. You'll discover that in the teardown, I'm sure. Make sure to refill it with oil when you have it retracted and to replace the rubber plug. If you search through my posts I think I've covered it or semi covered it 2-3 times. The first time I did it I think I used a writeup from and the factory manual There's probably another 5 pages I could write on it, but let me know what you have questions about after doing some reading.

    So ever since I got my '95 Cutlass Supreme convertible almost nine months ago, it's had an odd quirk in that it won't trigger the automatic shutoff at the gas pump. The first couple of times I filled the tank, I had a small fuel spill underneath on the passenger side--until today. I was very surprised when I was gassing it up today and the pump shut off! After the first two fueling mishaps, I had worked out a little procedure where I would put 10 gallons of gas in the car when the gauge was just below a quarter tank. Today, I was right at a quarter and the pump shut off just before the nine-gallon mark. When I got back in the car and turned it on, the gauge came up a little above the full mark so it was well and truly full without overflowing. Even better, when I got home there was no gasoline odor, which I usually experience when the tank is full. I'm thinking that when I got the rear struts replaced this week, the technician may have noticed a loose line and put it back in place without saying anything about it. If that's the case, I'm thankful but I'm not going to consider it permanently fixed until I fill up successfully a couple more times.

    Junk Yard Thread, Never ending

    I went to the pick n pull today. I've been thinking heavily about if I want to go through with the LQ1 swap or not, and I'm thinking I'll wait for a while before I go ahead with the swap. Here are a few pictures I took. The vert. The engine. Looks a little rough which is why I'm a bit weary of using this one for the swap. Interior was beat up too, this car had a rough past few years. Looks like the past owner was a shady dealer, as there was a sheet in the window making it very clear there was no dealer warranty, that didn't help improve my confidence in this engine. I didn't know they had a 5th gen Grand Prix in stock. Poor thing, it's the first time I've seen another 5th gen coupe in at least a month and a half. There weren't many pieces I could take from it, the grille I need was broken, it didn't have a spoiler so the rear piece behind the back seats was different from my badly dry rotted one, and the interior was really dirty. Such a shame too, as I love the dark cloth. Only thing I could really take from it that I needed was the door mechanism that broke on mine. Like I said, this interior was filthy. You can see the back of the cutlass in the top left. There were a few other W bodies but they were later ones, these were the only 1st gens that I saw there. Also they had a chevette. If anybody needs a specific part from these cars let me know, I can go grab them and ship them later in the week. I don't have much room in my apartment to store things so I was reluctant to grab parts left and right without anyone actively needing them.

    New to the site!

    Had a long day with the International but it paid off. I went down to the junkyard and grabbed a perfect master cylinder cap. The GM dealer said they weren't available anymore and they ordered me the wrong one. Oh well. I also switched over the cruise control accumulator and plastic vacuum lines. The 91 car had a broken line and was missing the holder entirely. I lucked out again with the 89 parts car as it had a perfect intact system with holder. I also practiced on some junkyard cars to figure out how not to break the line and holder. This vacuum line section was also a mess but not anymore! The driver's side inner fender was damaged/missing and the parts car saved the day again! Here's what was on the white car, what's left of it anyway. Parts car with complete inner fender plastic and hardware. Tabs were rusty but still worked with holding the screws. My original worn out decal cap and broken vacuum line. Line holder is missing.

    Ratchet strap is easy. Just don't roll the engine too far forward, and start putting pressure on the radiator hoses. I am due a plug change too. It's been a little bit over three years since I changed them. Guess I will keep on using the ACDelco conventional plugs AC R44LTSM since they have been doing good. New set of wires installed last plug change, so I hope they come off easy. I did use dielectric grease on the boots.

    Not sure. Since your car is a low mileage one, maybe that's why it still retains it. My 89 International parts car is relatively a low mileage car too. I stole it for the 91 car.

    10-4. I lucked out and took this one from the 89 International 3.1 parts car and put it on the 91 car. I found this NOS one and bought it for the 93 STE. I don't know if they are rare pieces but I always look for them in the yards. Looks like the STE has an aftermarket one. Yuck.

    Guys are always looking for the rear spoiler and tail lights if they are not cracked and in good shape. I would like the CD player if so equipped. Factory cup holder for another member. The little pin cup plastic pieces in the windshield header for all the vert guys. The rear quarter panel window sweeps/rubber. If you decide to not use the motor from it, I would like the little spark plug wire holder and bracket for the front spark plug wires. My STE is missing it I think. It's this little bracket and holder pictured here on my International that is mounted on the cam cover holding the red spark plug wires. Anything you can grab would be appreciated, thank you!

    I don't see why you would need to rotate the engine to put the valve in a specific place, that's generally to accommodate adjustable rockers. I have never done it on any 60 degree or 3800.

    So let me just say, MemphisMan is the man for countless reasons but he found this part on Ebay and texted me bringing my attention to it and I couldn't believe my eyes! A 91-94 CS HUD unit! After inspecting it, I can confirm that it is an NOS piece and has never been installed. The screw tabs have never been tampered with and the maroon cover is perfect along with the rubber seal that goes around the perimeter of it. Also, you can see the outside and inside lens/mirror is perfect, no scratches or fogging. The inside has no dirt, dust, or any debris at all! Incredible! It came in a very nicely packed box and was enclosed in a sealed bag. I would have never known about it unless MemphisMan said something and I'm forever grateful to him. The best part, I only paid $36.15 for it including shipping! There was and I'm sure still is a NOS HUD unit still out there that I posted somewhere here. The guy wants $1000 for it! Thank you Memphis! Your the best!

    Big brake upgrade differences

    Yes I change in their castings at all to simply improve on the front braking ability GM just installed a slightly larger rotor. To do that they had to move the caliper outward to relocate it in the appropriate position for the larger rotor. But really, when this platform 1st arrived there were droves of cars coming back to the dealers with brake issues. My 1st two GP's were no different, the cars would not stop very well in panic situations. The brakes are/were too small (front & rear rotors & rear caliper pistons), the boosters were substandard, there was an 1/8" air gap between the booster & the master cylinder pushrod, the diagonal opposed brake lines at the master sound good in theory but in a practical sense BOTH front calipers need to be driven off the same primary piston not split between the one primary & the secondary as the lines were installed, all tied together make for horrendous brakes.

    Dome light switches

    Hey, by the way, I just did a deal with the guy on ebay that sells the LED bulbs that fit into the dome light fixture. These are nice because they eliminate the heat build-up issue. So, if anyone wants switches and bulbs I can sell a set for $22.50 - that's 4 bulbs for $12 + 2 switches for $8 + $2.50 for shipping. For just the bulbs I would do 4 bulbs for $13, shipping included.
