oil leak V70-XC70

If there's motor oil leaking on your T-belt and S-belt
that's very bad news. You need to get the cover off and inspect ASAP.

Make sure that you use only full synthetic oil in that engine.
Dyno oil is poison as it can clog up the EGR and cylinder head oil passages.
Clogged EGR will raise crankcase pressure and put pressure on the oil seals
as Jim pointed out. The last thing you want is a blown out rear main seal.

Cheers, Bill
