Default Oil Leak in a STS Car.

I did some searches but, didn't find anything similar.

Here is my problem:

I can take my camaro out for a 1/2 hour and beat the hell out of it (almost constant full boost) around town and everything is fine, no problems. If I take it for an hour drive down the highway, I have oil running from the back of the motor to the cat. I drove the car 1 hour yesterday parked in my buddies drive and left 5 drops of oil?

What you guys think, I see no leaks anywhere? Rear Valve Cover Pass Side? I did remove the valve cover in the past.

Pull the inspection cap from your tranny and see if there is oil in the bell housing, if so, Rear Main Seal is leaking, and if it is you need to not drive it or get it fixed, the oil will eat up your clutch like mad. Check the valvecovers and see if the gasket got pinced or if you simply forgoto to plug some of the PCV system back in (I dont see it leaking as much as you say from just the PCV system, but who knows) There is ALOT of possiblities, on mine it was leaking from pores in the block, thats why I have a new motor going in tomorrow!

It looks like the oil is coming from the top of the Trans?

Tell me about it man Was leaking on the driver side toward the back of the block where the plug is alone a corner, it sucks. It was on a 98 block, apparently its pretty common on the 97 C5's, but unheard of on F-Bodies, usually the C5 guys lose about a drop or 2 every week, but since I have a ported pump it pushed through whatever thin layer there was over the pores and now it just oozes about 10 drops everywhere I park, and who knows how much when I drive.

I cant find a picture of it for a T-56. It may not have one actually, sorry. Check in the Manual section and see if anyone there can point you in the right direction.
