Locating strange oil leak?
A couple days ago my car started leaking oil more than it use to (leaks just alittle bit from the timing cover); but now it leaks a pretty good amount under the motor. I backed it out of the garage, and it left a trail of oil drops. I put a drain pan under the car to catch the oil drops and to see where it was leaking from but I cant tell. I coasted the car down, then started it to pull it into the garage. This time though there was no oil drops.
The oil is dripping off two, things. Its traveling onto the plastic torque converter cover, and dripping off from there. Its also dripping off the bottom of the oil filter.
Ive got the plenum moved out of the way, and the distributor out to get a better look. The rtv sealant on the back of the manifold is oily. Everything above the oil sending unit is dry, and pretty much everything from the manifold gasket below is oily.
Now I guess it could be the intake gasket, but I don't think it would be this big of a leak; would it? I also read about to much crankcase pressure or something, so I checked for any open bolt holes and I found one. Its right above the oil filter on the block. Anyone know if a bolt goes it there? Heres a pic of what I'm talking about. Maybe I have two leaks? Any ideas?
