Absolutely. Almost every 3800 vehicle needs to have those swapped out with the aluminum ones around the 100k mile mark. Not very hard to swap them out. That's one of the things I like about these cars. Fairly easy to wrench on yourself.

That kinda goes with the intake gaskets. Every lower intake on these engines I've ever done. I always write up new aluminum elbows if they haven't already been done.

@@scottpeterson4873 unsure. Rocker arms aren't a wear item. They don't just go bad. Possibly a manufacturer defect is the only plausible answer I can think of. What's odd is you don't have to pull the head to replace a rocker arm. Maybe there was a different issue that was corrected and Carfax just didn't get the whole story.

Look on the bright side. We can fit a whole fleet of cars in a five gallon bucket. We don't need a big hoovie barn.

My gtp has a bad wheel speed sensor harness on the left rear. It would go in/out and was super annoying because it would trigger the abs pump and traction control. I just disconnected the wire so it'll set a permanent DTC and fix it later. That was 2 years ago. Still haven't gotten around to repairing the harness

My 04 GTP with a little over 110,000 miles has an issue that feels almost like a slipping transmission. Not necessarily when shifting but accelerating in gear under moderate throttle. It resembles a bad throttle body, press on the gas to go and it almost feels like it's stumbling or the throttle isn't opening as it should. Transmission has always been serviced regularly, fluid is in great shape.

Coolant elbows! But everything else you said too.

I'm having a trans issue in my 07 GP base. I believe it's the 1 to 2 shift solenoid. It's fluctuating in functioning properly only when starting out from a stop you must ease on the throttle the every other shift is perfect and smooth. Otherwise if you hit the pedal normally it will Rev and clunk into first.

1997 Buick Park Avenue 3800 series 2. Love this car, love the power train. Replaced the lower intake gaskets around 120k. Replaced the MAF around 150k. Replaced the front wheel bearings around 100k, 130k, 160k, 200k.... Why the factory bearing last 100k, but no replacement Ive found last more than 30k?

3800 V2, Test for coolant leakage with lower intake gasket. Check with inspection scope through throttle body. Critical, avoid hydro lock! Check for rusted brake lines from ABS front to rear. Important to check to avoid blow out of lines. Check subframe bushings, four total, two inside pull through allowing subframe to drop. Critical to check!

Okay have the 2005 base 3800 grand prix. Has had the intermittent slam into gear upon takeoff for 70,000 miles. Has started getting worse but still only like once per drive cycle. Going to replace the cover internals ie wiring, solenoids etc.. being that it has veen happening for 70,000 miles I am crossing my fingers. Slipping seems like it would become much worse, much quicker. Have already cleaned throttle body and verified MAF is talking.

I just got my 99 gtp! My dad had one back when I was in highschool always wanted one. My buddy who has a regal GS with alot of mods had the gtp that was originally turbo and he put a supercharger back on it. He just replaced the transmission in it before I got it. I have noticed it slams in to gear sometimes if I slow down to around 5 mph and go to take back off without fully stopping and sometimes it will act funny shifting into second when I take off full throttle like almost slipping then grabs second really hard enough to spin the tires.
