    After my trip to Revo HQ today, one of the issues with my 5.5k hesitation etc is down to a faulty PCV. So, my question is, do i go for the PCV revamp kit(with view to possibly upgrading to c/c system at a later date), or go for any one of the catch can systems, and which one etc etc. Bearing in mind it is Christmas time, I'm tempted to go for just the revamp. Do the ones lIsted for MK5 Golfs etc fit ok? Dubtek seem to be competitively priced

    What does the PCV do? Or what does the BSH kit do?

    The PCV is basically a crank case breather which re-circulates back into the intake, and has a non return valve to prvent pressurisation when the inlet manifold in under pressure, ie when on boost. One of the weak points is this NRV which, when passes, leaks boost, and is the cause of rough running, poor idle etc

    The BSH kit does away with the NRV part of the system, there are other kits, and also catch cans, which act as a seperator and allows liquids which are entrained in the vapours to drop out into a catch can and be drained off.
