if the balance pipe orings are worn or split what causes can this have to the performance on a tt engine?
Would be a highly possible cause of air leak. Very cheap and easy to replace for a better peace of mind. Just be sure you got the perfect-sized rings specifically for our cars...
balance pipe O-Ring sizes .... you need:- 2 x 34ID X 2.5mm. 1 x 18ID X 2.0mm. available from Allied Bearings and Seals if you have such your way ...
I bought some genuine ones but havnt put them in yet, there is a spilt one in there and I'm having boost issues since it has been split, so this is a possible cause?
Yes. With that amount of pressure inside, it will definitely look for even the tiniest slit or hole for exit...
