I got some work done to my car. Upper and lower intake new valve covers and a throttle body. Also replaced some gaskets due to a antifreeze leak and oil leak. Now after I drive my car for about 5 to 10 minuets it starts making this LOUD whining noise.I figured noise is comming from the oil cap and dipstick. When I remove it it lets out a ton of air and the noise stops as long as the oil cap stays removed. I was told this is ok and someone else said that this is not good. The pcv valve or maby its called the pvc valve is connected. I can not fit a breather on due to the oil hole is on the drivers side and there is no space for one to fit. Any one know why this would be happening?
