SOURCE: how much to change a oil pan gasket for 2001 grand prix 3.8 gt

If you want to repair the oil pan I would also check lower engine mount for leaking oil and cracks in anti sway bar near fitting's. This due to engine mount is oil filled. OEM sway bar is made of tubular steel and they crack easy. Replacement sway bar is solid steel. Here's the kicker. When they pull the lower frame to service oil pan. The engine mount and sway bar are attached to that frame. A honest mechanic should only charge for parts ($35 for mount and $100 for sway bar) and maybe a extra hour. My mechanic did all in 5 hours. FYI gasket is only $35 bucks. Good luck

I have a 01 pontiac bonneville ssei with supercharger and its smoking bad. some people say it my be the supercharger seals. and i should replace it

Is the smoke white or bluish/black? The white smoke could indicate leaking oil seals or even a coolant leak. The 3.8 is more common for the intake manifold and plenum gaskets to start leaking and causing white smoke. If the smoke is bluish/black,check the fuel pressure regulator to make sure it is not leaking and fuel being sucked into the intake via the vacuum line.

What would cause all of the oil to leak out of my 1997 Pontiac Bonneville if it isn't the oil pan, or oil filter?

So there are obvious drips on the floor then?
Assuming those two which you mentioned are fine, then the other most probable and common oil leaks are from:
Rocker cover gasket(s)Front or rear crankshaft oil seals.

My Grand Prix GXP is using a quart of oil every 1500 miles. It does not smoke or leak! What could be the problem?

If you're vehicle has high mileage you may be loosing oil through you're valve guides. you may not notice this as the catalytic converter would burn off the oil. Or check you're radiator if oil in water head gasket is ready for replacement.

Yes you just have to swap all the brackets,and poss oil pan and oil pump,and poss intake,which i would do before installing motor due to the fact they are known to leak oil into the coolant.(the ihtake gaskets).

Oil Leak

i would have to say the oil pan gasket. that is the one that I have replaced more often. it is ever usual for the rear main seal to go out but not impossible. but i would have to say oil pan gasket.
hope this helps and if you need anything else let me know. happy holidays.
