Some of you may know i have a series 3 thema with the bottom end gone, it ran a bearing on piston 3 as per photo enclosed.
I have now ripped down a running series 2 engine and am planning to swap the blocks as they are the same but i seen to have valve marks on the series 2 pistons so i think she has broken a belt at some stage and also there is a very very slight lip on each of the cylinders at one side about 10mm from the top.
Im wondering if i need to replace pistons and if i have bent con rods from a previous belt snap. i know this would be unusual!
Other strange thing is the all pistons seem to have valve marks on them, i thought it was impossible for all 16 v to make contact??
So have you guys got any advise or ideas???
