I have read many discussions about zd30 patrol maf sensor being downstream of engine breather and getting coated in oil from engine breather , even with a catchcan ,and having to remove and clean . My question is why not switch these 2 around and then it will be upstream and not get coated in oil ??? Am i missing something ?? Thanks steveg
