803cc piston rings
803cc piston rings
my 803cc engine is stamped with a diamond shape containing a figure 3 on each piston and adjacent block. I presume these are standard size as I believe they would be stamped +20, +30 Etc. am I correct? Also I have found it impossible to locate a set of standard rings for the 803, any assistance in obtaining same would be much appreciated.

Re: 803cc piston rings
they are original 'MOWOG' pistons, the number in the diamond denotes the grade which is should also be marked on the top face of the block, basically the factory matched the pistons to the block, there are also grade 2 etc16Cabulrd wrote:my 803cc engine is stamped with a diamond shape containing a figure 3 on each piston and adjacent block.

Re: 803cc piston rings
So they could be oversize if the engine has had a factory 'gold seal' rebuild?A40FARINAGURU wrote: they are original 'MOWOG' pistons, the number in the diamond denotes the grade which is should also be marked on the top face of the block, basically the factory matched the pistons to the block, there are also grade 2 etc
Has the engine still got its engine number tag fitted?

Re: 803cc piston rings
My A35s 948 is a goldseal and I remember seeing an oversize mark on pistons when we decoked it.
Can't remember if they were plus .010 or .020 though.
