The PO has removed the PVC assembly and fitted the breather tube to the side of the motor. He also put on a non vented TR3(A) valve cover with the oil filler cap at the front of the engine. He said that it "hit" the hood because of it being in the front and the height of the cap. I also got the original vented valve cover. Since I do not need the vent I was wondering if anyone knew of a lower breather cap that can be used on the TR4 A that would not hit. I know I can use the original and put a breather filter on the vent but I would use the TR3 valve cover if it can be used as I am not sure I would like the breather filter sticking out on the TR4A one.
