Touchdown! Greaser!
Superior has two significantly different documents showing ring end gaps on their website for the IO520. One is obviously older, one a newer SL, but I am wondering why they would continue to list the older one at all.
I talked to the tech rep and he simply said use the newer one.
Good thing I happened upon the newer one first before using the older one - or is ring end gap not so critical?
I think it likely someone will stumble upon the older document and use it, might there be any consequences?
Of course it is entirely possible I am misreading the documents and there is no disagreement!
A. This is "Piston Ring Sets, Ring Applications and Recommended End Gaps and Side Clearance for Continental Engines"
