Thanks Karlos. I noticed from reading other threads that you seem to favour blocking off the metering unit form the breather also.

What is your set up with the breather pipe now from the oil separator?? Do you have a catch tank ( or similar ) or do you vent straight to atmosphere??

I have merely attached a small breather filter to the end of quite a long samco oil resistant hose and let it vent down near the front anti roll bar.

Seems to be different views on catch tanks etc..and also fumes generated. Mine seems ok at the moment. Cheers
