Hi everyone.
I have a 1960 Crusader sport which has given me no problems for many years,and only last week gave it a rebuild new piston rings had warn oil ring, and valves and guides, as one of the guides was warn out, i took it for its 1st run yesterday an it runs sweet apart from 1 problem, it is blowing alot of oil out of the breather under load, as in pouring out...! have checked all oil lines all seams good. if anybody can help with information to why this is happening an a way to fix it will be much appreciated.

Cheers

Patrick.

Patrick did you get the bore honed? crank pressure pressure build up from the rings not seated will cause this problem
