Chashend56 Posted June 28, 2018 Share Posted June 28, 2018 I am rebuilding the engine on my 13/60 Estate and am presently refitting the pistons. Does anyone know if there is there a correct angular position for the gaps in the compression rings relative to the gudgeon pins? The instructions for fitting the bottom oil rings which came with them were very clear, but no mention of the compression rings. Information on the internet was quite conflicting. The only thing that was clear was that they should be at 180 degreees to each other. A friend with experience of rebuilding Mini engines told me it doesn't really matter where the gaps go as the rings rotate anyway when the engine is running.

JumpingFrog Posted June 28, 2018 Share Posted June 28, 2018 A lot of people do recommend not placing any gaps on the major thrust side of the engine. This would be the manifold side of the engine... But as you say, rings are supposed to rotate so in practice I doubt it matters. Quote Link to comment Share on other sites More sharing options...
Gt6s Posted June 28, 2018 Share Posted June 28, 2018 Ring gaps really only need to be staggered does not matter how. Laurence Quote Link to comment Share on other sites More sharing options...
Chashend56 Posted June 28, 2018 Author Share Posted June 28, 2018 Thanks for you replies, most helpful. David, all the best for your upcoming trip, I've read the mongoltriumph stuff and it's absolutely amazing how much you've done on the Estate. Quite an inspiration to me as the C Posts on mine are just as bad, if you know of any with decent bottom halves anywhere please PM me or post on here.
