Cosworth stem oil seal
What are the best valve stem oil seals to get,rebuilt my engine 1500 miles ago,and the seals are p*****g oil past,the plenum was full of oil(well it wasn't full but had a lot of oil in it).It had new guides,and seals.the exhaust side was leaking to.Also ive been told can re use wrc steel head gasket and long studs,is this true.
thanks matt
