Well, I swapped my oil pan gasket, changed timing chain... had everything torn apart. Rear main was replaced about 2 years ago. It looked good and clean. I got the car all back together last Monday.. wasn't leaking a drop all week. Get in to drive it today after it sat in the garage on Sunday, look on the bellhousing and theres a drip of oil haning there and a little spot about the size of a quarter on the floor.... UGH!!!!!!!!!!!!!!!!!!!!!!!!! It has to be that damn rear main, unless the oil pan bolts have loosened up a little and it's leakin but I don't think thats it. It's going to stay leakin a little bit til next winter b/c I'm not takin this damn thing apart again!!
