Hello All, I did some searching last night and failed to find the information I needed. I have google and my parts place stumped.

I am rebuilding an 2007 (build date 06/07) Turbo R56 6 Speed Mini. I have ordered Piston rings from two different vendors and they both came in, different brands but same sizes. The oil spacer does not physically fit into the piston ring groove. I was wondering if mini changed pistons mid build or? From my understanding the oil ring was an issue on these cars... the reason I am rebuilding this one.


The top compression/oil rings sit in the piston as should and I checked them in the cylinder, all good. The oil ring just appears to be slighting to large. I will log into my phone and post some photos.

If anyone has any information I would appreciate it! Happy Saturday.
