'04 3400 with 140K on it.
Just throwing this out there, but should I swap out the intake gaskets now while the car is parked for the winter? I keep reading horror stories about them just "going quick & bad" so its bothering me! As of right now its fine. They have not been replaced as far as I can tell & I see no external signs of leakage. I did both valve cover gaskets checked it out externally very close. Its just that now is the time to go after everything that could be trouble soon.

Are the 3400's really that bad? I've had a 2.8 Firebird & a turbo 3.1 Grand Prix STE that I beat on & this was never an issue. They are "basically" the same with a different intake manifold so I'm hesitant. If nothing else it gives me a chance to clean up & paint the intake Cool

Thanks!

If you have a write up and half a brain it shouldn't be too bad. But... I wouldn't be doing the job unless I had a reason to do it.

If you have a warm garage to work in and the time to spend. GO for it.

If not leave it alone.
