1998 S70 GLT Continuous Mysterious Oil Leak

[scot850]

I had all the main engine seals (cam/crank/oil pump 'o' ring) replaced at the dealer using OE parts. The crank seal was leaking by the time I got home! Just had it replaced again, and all seems fine for now.

If you have had problems with the PCV, it can easily blow out a seal. The crank seals and rear 'front' cam seal at the pulley are both known to be difficult to seat correctly even by the experts.

There is no easy way around this, but still recommend you make sure you clean the whole area off again, and take for a short run, or run the engine for a short time and watch it. The oil could just be stuff picked up by the cam belt and being thrown around the engine bay.

Once you have done this it is time to pull the belt and find out what is going on.

Make sure your rubber seal inside your oil filler cap is nice and flexible - It will get rigid in time - I had a great deal of oil in the engine bay and that $3 part fixed it - Simplistic but worth trying

OP explains it was replaced on Sunday, thanks though.

Check the black 10mm bolts on top of engine to see if one might not be tight. When I bought my car a year ago, I had a leak that filled up the top of engine and sparkplug holes. Oil would puddle up and run down the back of engine. Found out one of the black bolts was loose.
