massive end gaps
yep, seems like might be a plan these days to budget for new rings whenever pistons are bought.
add to that the fact that in modern stuff rings come ready correctly gapped (wouldn't want mechanics get their hands dirty on a file now would we).
I've bought three sets of pistons since 2000 and all of them had rings with gaps to large, and that included a set of AE (which was Hepolite in US I think )
These days a name is just that - a name - has nowt to do with past glories
(am I beginning to sound like an old F***) *shhh*
