1997 Pontiac Grand Prix Q&A
1997 Pontiac Grand Prix Question: I have an oil leak and don't know where it's coming from?
I have repaired many different oil leaks, but without looking to find out where the leaks is, I can't tell you what to fix. Have someone look at it and find what is leaking. Possible, oil pan, front or rear seal, valve cover gaskets. - ProfessorG
I'm assuming you don't want to drive this vehicle anymore. Your oil leak is to severe to drive this car anymore until you find where the leak's are. After all it's only 17 years old. Understand that oil is a liquid. This means an oil leak on a vehicle that's 17 years old you need to start at the top and work your way down. Do the valve cover gaskets first and then thoroughly clean the under side of the engine. After the underside is clean I would put an oil dye in the crankcase to really see where to go to the next oil leak or leaks. Lots of auto techs say it's the oil pan gasket when they haven't even done a dye test. So tell me is the odometer read at least 150,000 miles. - PARTS GUY
