Looking at my engine number, the last character looks like a skewed 'N' Its both the same on my TT and NA engine. But when i asked for MickW's number, he's ends in a 'W' With closer look at the 'N', It does look like it was 'meant' to be a W. So im thinking it may have been a stamp problem from factory. Its just weird that its on both my TT & NA engines. So the question is, What is the last letter of your engine number? And has anyone else seen this before? Ill try to grab some photos tonight if it helps.
