• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Can LIM gaskets leak oil? (not coolant)

    2001 GTP Coupe I have a very bad oil leak somewhere. Losing about a quart per 25 miles. Can't tell from drips on the ground where it is coming from. Power steering pump is also leaking so that makes it harder to tell. Mechanic just told me the oil leak is from the intake manifold gasket. I...

    FYI: Coolant bleeder alternative, Dorman 13960 (brake bleeder)

    For reference, my car is an '01 Pontiac Grand Prix GTP. I assume many others use the same coolant outlet and bleeder. The coolant outlet to the upper radiator hose (thermostat housing) has a bleeder screw for getting air out of the coolant system. The head of the inner screw is broken on mine...

    ABS not working even after module repair

    ABS light has been on (and traction control off) since I've had my '01 GTP. Can't get any reader to connect to the ABS controller. (I know standard OBD ones don't.) Can't get any wheel speed sensor readings at all in Android Torque (even adding the GM PIDS.) Fuses good. I sent the module to...

    I found the fitment problem with Spyder tail lights (6th gen)

    Mine is a 2001. I expect the same is probably true for other '97-'03 Grand Prix. I bought the Spyder tail lights because my OE ones were hazy, cracked, leaking water, blowing bulbs frequently, and I didn't like the OE appearance that much. When I went to install them, I found it was difficult...

    Any short, quiet(ish) mufflers for '97-'03 GTP?

    When I knew my exhaust was rusting out, I bought Walker OE-style mufflers and a TruBendz stainless 2.5" piping kit that fits the stock location. Mufflers fell off before I could get to it. Now I need to get it driveable. Unfortunately, I found the TruBendz piping kit is not compatible with...

    Diagnosing lifter tick: Sticky? Collaped? What?

    Are there any guidelines for determining whether "lifter tick" is because of "sticky lifters" or an actual failure of the part? Sunday morning when I started my '01 GTP, it made a lifter tick that's easily audible inside the car, with the hood down. This is the first time it's done that, and it...

    Diff between 6th and 7th gen dual exhausts?

    What are the differences between the dual exhausts on 97-03 and 04-08 Grand Prixs? I thought they were the same, but they're not, at least not 100%. The midpipe seems the follow the same path, but the muffler inlet size is different, according to Walker. A Walker muffler for 97-03 has a 1.875"...

    Remove square bushing "dog bones" attach to? (The one people flip)

    What is the term for the square bushing the "dog bones" attach to in front, above the radiator? The bushing people rotate 90 degrees for "dog bone flipping." Is there any way to remove it from the bracket without damage, and reinsert it? There's a ridge around the rubber that fits into a groove...

    Check valve / pressure regulator to tune boost bypass actuator/solenoid?

    I have some questions about a potential mod I thought of (or at least that I haven't found in any Google results.) First, let me describe what I think I know about how the boost bypass actuator/solenoid works. Please let me know if this is correct. ----- The boost control actuator is...

    Which 2nd gen Buick Park Avenue has a HUD?

    I was researching 2nd gen Buick Park Avenue Ultras, and ran across a forum posting where someone was describing problems they were having with the HUD in their 2005 model. I didn't even know they had HUDs, so I tried searching more, but can't find any information that confirms or denies this...

    Electric power steering retrofit? ('01 GTP)

    Is there a solution (aftermarket, or borrowing OE parts from another car) to convert '96-'03 Grand Prix's from hydraulic to electric power steering?

    Knock, knock, knock (Who's there?)

    A few minutes after I start driving (when the engine is cold,) I hear a faint "knock, knock, knock" sound. Always three, same even spacing. Can't tell where it's coming from. I assume since it's consistent that it's something normal, but I'm curious what it is. '01 GTP

    Are all 3800 cam gears the same, or different per engine type?

    E.g. can you use a timing chain set (including gear) from an L26 on an L67, or other similar combinations, or will that throw the cam timing off? I think the chain is probably the same, but I'm coming up with different part numbers for the cam gears. I've read a few posts on various forums that...
