Also regarding ring sizes shows two different ring options for std rings, 0 and 00. I’m presuming 00 are to be used on a higher mile engine , any tech info on this appreciated ? £40 price difference also between the two different part numbers I understand measuring end gap etc. ..... Any specific end gap for csl.. thanks for your input James. ,,, speaking to my local engineer suppliers today, they say they would use the 00 term / measurements, to indicate a higher degree of machined /measured accuracy.

..found ring clearance, if anybody needs to know, also main bearings shell Difference....as for ring sizes bmw shows three sizes, 0 and 00 And +0.20 From what I’ve found I think it is the bore size, as on engine block spec picture bellow, So I’m guessing not all blocks are the same, and need to be checked when ordering pistons and rings , unless anybody knows differently, ??? Possibly+0.20 is first oversized,
