As per title.....

I've recently changed from a standard rocker cover to an alloy RS motor sporttype (CVH engine).....

During a trackday on Monday, it was leaking alot of oil...

The rubber seemed to be very hard, and I think this may have been the cause..But I also wonder if these rocker covers breath as well as the seemingly crappy pressed tin ones?...

Engine is a high power 2ltr (N/A) CVH, and the leaking only seemed to happen on track, and not on the drive home...

Also, anyone know of a better spec oil for the CVH..I was also noticing the oil pressure dropping off slightly when the engine temp got hot (i.e. over 100'C), I'm using mobil 1 semi synth 10W 40........But engine is pushing over 200bhp, so wondered if there is anything that can cope with the temp better?....

Thanks.
