thanks for that... will have a look tomorrow...

so, am i right in thinking, reason for the oil leaking, is due to excess pressure???

if so, i did notice hole at opposite end of cover next where oil breather system is plumbed into... which would surely let any unwanted pressure out??

also, system has an oil catch tank??? does this make a difference or help with solving problem??

but sure it is coming from oil filler cap?
