Do most guys replace there Oil catch can's on there M12's? If so,Reason for changing it out? Also,does anyone have pictures and explanation of what needs to be done for hook up.
The reason for doing it is because the original rusts and you can have bits of rust debris in the catch tank that could find there way back into the engine.
There was a thread only a few days ago explaining how to fit it
It's easy to fit. Get it from pro alloy and then once you have it we can tell u how to fit it. You will need to plug an inlet pipe. I think pro alloy do the plug also but best ask them.
