Ring End Gap

Recommended Posts

Can anyone tell me the factory recommended ring end gap for a M116 Alpina (new rebore, piston and rings)? My service manual has 2 listings:

Ring End Gap     .002

New                     .012

Thanks.

If you don't get a better answer, I'll say that 0.002" is too tight for anything.   I'm guessing it may be a misprint and should be 0.020" as the service limit.  0.012" seems roughly right for new rings.

At the risk of stating the obvious, the purpose of the end gap is to allow clearance for expansion as the ring gets hot -- you do not want the ends to ever touch.  Minimum end gap is a function of bore diameter and operating temperature. 

New end gap is typically on the order of 0.004" per inch of bore.

Thanks. One reference I found said to use .004 x bore for the top and .005 x bore for the lower ring. Thanks again.
