- Clean the oil stain and starts monitoring the leak. You may need a flash light to look carefully into the cam seal areas.

The exhaust cam seal on her S60 were doing the same thing. Was dripping behind the plastic and onto the sub frame. Very hard to pinpoint.

There's nothing else that would leak there IIRC.

cn90 and dlundblad -

are you saying that no oil was on the cam sprocket or belt even thought the cam seal leaked? I can see through the slots in the exhaust cam sprocket and no oil is visible. Nothing on the inside of the sprocket or belt. On the intake side I have VVT so can't look directly through. I got the good crank holder tool from CTA in hopes that the problem was down low. Debating if I should get the good cam holding tool and try replacing cam seals. Timing belt due in 15K. Easy to run up the $$ with these P2's. May be time to just give in and get a Honda!

The belt and VVT were spotless albeit I imagine not catching it in time would have yielded much different results.

P2's are getting up there in years. Don't blame them for needing a little PM.

Have you ever done a Honda timing belt? Volvo P2's are very user friendly IMO.
