I looked under and the oil filter, oil pan, transmission pan and near by areas of oil pan are cover with oil, don't know if it'* comming from the top or the bottom,,, I need help cause I don't see a big difference in the oil level tester. I don't want to take my car to the dealer it doesn't like it...Please help...

Maybe you should clean all the oil off the bottom of the engine.. then run it for a bit then see if you notice where the oil is coming from

Hate to say it but that sounds a lot like my oil leak, in the end the main leak was from a blown intake gasket they said lower intake to be exact. It was also leaking from the main seal.

I tried cleaning it and letting it idle that did not make the leak show it self I had to drive it to get it to leak.

Thanx everyone, I'll try cleanning the exposed motor oil and run the car around the block then lift the car, and check for leaks.

Has anyone changed the seals from the intakes before? How hard is it..? I will do it. But I need a little bit of assistance.

Thanx
