Bad oil scraper ring - fix?

Sorry - I meant to post this in the 912is area

This is most likely a valve guide seal  have to check service bulletins for your serial number some motors had a machine cut into the intake port.... Never had a bad oil ring.. possible the spring on the oil ring is over lapped on assembly... Ring position. . All service bulletins items 

I just ran a search for all SBs for my SN. Unfortunately there is not one addressing this issue. But again, I screwed up and meant to post this in the 912is forum

HI Michael

The ring is not subject to failing unless you have been running leaded fuel a lot.  The only way to find out is the removal of the cylinder to inspect the ring.  If the ring is stuck in the piston ring groove then it may break on attempting to remove it.  The small spiral spring in the oil scraper has no special position so that is not likely the issue.  It is possible that you may have higher than normal crankcase pressure,, this would increase the pressure inside the valve train (under the valve caps) and perhaps lead to oil being pushed into the exhaust from the valve guide to valve clearance.  Remove the exhaust pipe and inspect for signs of oil coming from the guide.  

Just a suggestion.

Cheers
