Hi All,
If someones A7/10 regularly destroys the rocker box gaskets,
The first thing to check is that all the main engine to frame bolts are tightened correctly
All the sealer in the world will not work if the engine is doing a rumba ????
If the standard breather is correctly set up there should be no problems (unless of course the rings/bores are in trouble)
I have previously posted details of my modified head steady, and can only say no leaks after 10 years and lots of miles
To my way of thinking an open breather just leads to lots of pushing and pulling air ???? ????
Cosmic,I have had lots of problems as well with a dommie, finally kinda sorted crankcase breathing into oiltank and a oneway valve on another pipe from the tank to atmosphere
Has anyone heard of how a Bunn system works on an AJ/Matchy big twin??
These suffer from pumping engine oil into the primary case
Cheers
