Think it's more a case of telling us what he's into at the moment,
and what he found.
Ok, so there may well be a leaning towards saying that the original
VW stuff is a bit below what he expected, BUT....
as it's an old T5 then I would be expecting the gaskets to be worn..
and yes, the clips alsomight have gone weak.....but when all is said
and done, those parts were not built to handle/hold the huge boost
that he now says it has been made to produce.
Who knows, if it were unmodified/standard, then possibly the issues
he found quite possibly wouldn't be there now.
