Ok, i've got pretty much all the oil leaks worked out of the 90T we bought a while back. But the underside still looks wet. I've done the whole front and top end. It looks like it's leaking from the CPS. I'm assuming it's the Oring on it. Do they go bad often? that and on the driver side that 3/4" hose from the valve cover down to the crank case is all dry roted and cracked. Only 2 spots I can see it leaking from.

yea, my CPS o-ring was like a rock, I had to chip it to get it off... Also, I had oil leaking from one of the cam caps a while back, was a really bad leak, smoked and everything else, just tightened the two bolts on the front exhaust cam cap, and problem solved! Also, check your valve cover gaskets, they seem to like to leak from the front!
Hope I helped, and here's a link to the thread were someone was having a similar problem...

ok, well i'll start with the O ring on the CPS. looks like it's coming from there. Valve covers i just did a while ago, they were leaking. dry as a BONE now.
The Exhaust heat pretty well cooks any and all rubber parts on that side of the motor.
Even when mine was NA the O-Ring on the Distributor was dead and had to be broken into pieces to remove.
