ok so looking over for more evidence that my rear main seal was causing an oil leak, and i noticed that at the back of the motor that the spot that my pcv valve was supposed to be was empty and open, well luckily i found the valve on the back of the motor but what i want to know is if this fell out would it cause a pretty big oil leak? ---

maybe it popped off from excessive blow by, bad rings, in that case, yes. ---

well last summer my father in law pulled the intake off and some of the hoses with it and i think when he did this it must of came off and it just never occurred to me that it would have. it started to leak oil like a few days after this happened. ---

yeah im pretty sure my plenum pierced the driver side valve cover but not enough to cause that kind of oil leakage. i plugged it back in and took my son for a drive init, didn’t smell anything till i got on it on 29 but just figured that was some oil that had been sitting on there. ---

How much oil have you been using quarts vs miles? I wouldn’t worry. Just keep an eye on that dipstick for a while. And just look at it. ---
