Hey guys, just one question. I have recently done some work to my engine and i happened to notice when i take the oil cap off the cam covers there is a small amount of pressure coming out of them. Is this normal? Every other car ive seen has vacuum at the oil cap when you take it off. Im just confused. I have just hooked up a catchcan and its setup basically stock minus the throttle body vacuum. Is this my problem? Any opinions are welcome, please help me! Thanks.
