Its never been replaced.
The car is an Ed30 with 47k. Im tyring to find out where a high pitched air squeal is coming from and when looking found the dome on the PCV to be drawing air in quite bad...Im not sure why the dome has a moulded outlet on it?
Ive plugged the hole up for now but the car is still making the high pitced air noise, but i cant locate where its coming from?
When i switch the car off the noise appears for about 2-3 seconds as if its releasing air pressure from somewhere?
