Leakdown test is the one I'm after - and I don't have access to the right size compressor nor a leak down tester currently in my possesion and I'm running out of time and unable to run around chasing these items.
I've comp tested before, thats easy enough - but I'm not happy enough just to do that this time, want something more comprehensive
Would prefer to take it somewhere that has had experience with these motors than a local mech, I've already been knocked back once because one shop didn't want to do it
