Whistling noise f30 N55
after a coolant flush I turn the car on and a super loud whistling noise was coming from down the hood.
I check my pcv with the fire test and was and pcv valve fail. I changed with the upgrade kit . didn't glue the very top only sides as supposed to be .. turned the car on and after little warm the whistling noise started again but now 80% less before car had a terrible idle and now is 90% good . engine shakes a little on idle . test pcvnwith fire again and passed .. its working well. I have no oil leaking at all . gaskets looks great. now I try to open the oil cap when whistling and there is a lot pressure and the whistling go away .. is it gasket problem ? why I don't have leaking problem? pcv solved 80% to 90%. by the way car has a fault for valvetronic but when I turn the car on the is no noise coming from the hood as a broken one sounds. |
