Brandon72 Posted March 9, 2010 Report Share Posted March 9, 2010 My car's been in the drive way for month now. I just started it up and found this under it. It's a brownish, milky color. Does anyone know what it could be? All fluids were checked and are ok. Car runs great and has been running great. Hope I don't have a blown head gasket. There's no milky stuff under the oil cap or on the dipstick. Thanks, Brandon Quote Link to comment Share on other sites More sharing options...
Brandon72 Posted March 9, 2010 Author Report Share Posted March 9, 2010 I just looked at it a little further. Opened up the radiator and the coolant smells like coolant and is green. I did add quite a bit of coolant 3 months ago. The whole underside the car is caked with oil from previous leaks. I'm thinking a leaky water pump.

MonteCarloChick Posted March 9, 2010 Report Share Posted March 9, 2010 Model and engine in car? Looks like an oil leak to me Quote Link to comment Share on other sites More sharing options...
Brandon72 Posted March 9, 2010 Author Report Share Posted March 9, 2010 Model and engine in car? Looks like an oil leak to me 93 Grand Prix LE with 3.1 engine. Very well could be just an oil leak. Radiator doesn't want anymore coolant, so probably not water pump. Quote Link to comment Share on other sites More sharing options...
3.1cutlass Posted March 9, 2010 Report Share Posted March 9, 2010 Bet money it is the oil pump drive seal. Quote Link to comment Share on other sites More sharing options...
AL Posted March 10, 2010 Report Share Posted March 10, 2010 On a 3.1? Quote Link to comment Share on other sites More sharing options...
alec_b Posted March 10, 2010 Report Share Posted March 10, 2010 Sure the 3.1's and 3xxx series leak from the drive seal. Just not as much as the LQ1. Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 10, 2010 Report Share Posted March 10, 2010 My 3.1 finally started leaking there too haha. Don't rule out power steering hoses either. Quote Link to comment Share on other sites More sharing options...
Brandon72 Posted March 10, 2010 Author Report Share Posted March 10, 2010 Where is this drive seal? I read some posts about removing the rear head, etc. Then another post said to remove plenum, tb, etc and it was located in that area. Is this a easy job? I have to remove all that anyway for new injectors. Quote Link to comment Share on other sites More sharing options...
Hairdo12 Posted March 10, 2010 Report Share Posted March 10, 2010 Its under the throttle body on the 3.1. Throttle body should be the only thing you need to take off. You may also need to loosen a fuel line at the rail, but you don't need to remove it. Its easy, just can be a pia when you try to stab the gear back in. Mine got so bad about 8 years go I would basically dump all my oil on the driveway when I'd start the car. The o-ring was like very brittle plastic and just crumbled when I touched it with my finger.

GnatGoSplat Posted March 10, 2010 Report Share Posted March 10, 2010 My leaky tranny fluid gets that color when combined with the A/C condensation drippage. Looks like a bunch of crane flies met their demise in that stuff. Quote Link to comment Share on other sites More sharing options...
