Fitted Bosch :) can you get more than 20psi on a K14??

I could be leaking from any join or connection in the pipework between the turbo and the head...........likely suspects are inlet manifold gasket and adaptor

I could be the wastegate creeping open I suppose, but there seems to be a lot of people using that as an excuse at the moment

Cheers pal will have a closer look and reseal the top adaptor the manifold could explain how the rear of block and bulkhead has a light film of oil will get a new gasket this week

my reason for thinking the wastegate is opening is it wont hold boost and drops rather quickly as had boost leak in past and gradually drops but this plummets on the guage
