T?cam Head Service Bulletin.

PostPost by: clemf » Wed Oct 29, 2003 9:41 pm

I've had a problem with excess oil from the breather pipe being sucked into the engine with the result of lots of smoke. I've heard there was a service bulletin issued in the late sixties that recommended drilling a hole in the head from the top into the breather chamber. Has anyone come across this, have any details or has got the same problem?

Clem,
Go to www.gglotus.org then to Tech section, under Twin Cam you will find an article "oil scavenging" this may be what you are looking for.

:huh: Thats the right one but the diagram is so bad you can't make out the dimensions and I don't like the idea of guessing where to drill the hole !
