Have you ever changed the plastic one way valve in the pipe work off the underside of the inlet manifold Steve?
I’d advise everyone to change this if it’s still the original.
I was chasing a boost leak or a long time, then it developed an oil leak from the front cam seal, which turned out to be this valve leaking when on boost, pressurising the breather system and the top of the head and leaking past the seal.
Changed the valve and got nearly all the boost back and no more leak.
