Having problems with your 2000 Pontiac Grand Prix ?
Intake manifold gasket on 2000 3.1 Vin J (Fed) replaced in '08 - then - distributor (?) plug/gasket failed and drained oil from crank case. Engine now extremely noisy (always had lifter noise) and runs - yet I fear it has catastrophic damage. Can/should this engine be repaired? Better to replace? Boat anchor? Please help - backyard mechanic and dad of driver seeks a ton of assistance on this one - the car has been great other than the lubricant issues from Garbage Motors!
IMO, you have a serious internal engine problem. Probably a bad piston and ring failure. If the car ran hot, the damage could be extensive. the head may have warped and have to be cut flat again. Or replaced. Not to mention the piston . Check the compression on each cylinder. If one or more are lower than the other ones . the pistons are jacked.
