Hi all!

I was wondering if anyone could offer advise about my 88 XL 1200....
It was an 883 / 1200 conversion about 1600 miles ago, and the last 200 miles I have been having a severe blow by or oil leak at the crankcase breather port on right side of engine. I installed an aftermarket filter in the 3/8 hose, to keep the oil from saturating the right side of my bike. I have been told there is a valve that goes bad behind the cover?????????? Or could this be a mechanical failure w/ the rings??/ Please help..
