so my car isnt leaking it or if it is its burning it. i have replaced the pcv valve done a compression test all checked out fine were all pretty close i also for some time put a piece of cardboard underneath the car and not a single drip i can easily get a low oil light halfways through oil changes depending on how ive driven and i called for recalls and stuff and there are none so is it the valve cover? ive heard they leak i cant really see the rear but the front is clean
