have a friend with 98 mondy 2.0 zetec estate.
Managed to boil it solid so had to have engine rebuilt.
So far so good until recently 12000 miles later car keeps blowing camshaft oil seals out of head.
obviously understand that there is excess pressure in engine just wondered how oil system works on these engines as fords are not my strong point. has correct 5w/40 oil in engine.
i think oil pump release valve stuck.
any ideas?

I doubt if increased oil pressure would do this
First check the breather system, then check/change the seal, then get a garage to do a pressure test.

I could be wrong, but I was certain the the Zetec needed 5W30?
I was always told that 40 grade would knack it?
