Re the breathing heavy issue - you're always going to get crank case pressure but again it depends on how much. Does it run ok? If you've tested for compression and leaks and all appears to be ok then I'd get it down to a tuner for an expert opinion
the problem is when i rev the engine u can see the bubbles/pressure building in the bottle which increase with the revs so it must be compression leaking into the cooling system??
i just cant how
the pressure in the oil breathing is too much to b normal i think!
im just going to check to see if that raises with revs because i think they could b linked!
