Hey everyone, so just recently my aos went bad and I replaced it. I never did clean out my intake with oil residue though. However, it keeps burning oil. Last night, I was 4 QUARTS (I kid you not) low. And it's going down on my oil level from last night (still continuing to smoke too). It'll burn oil at an inconsistent rate... not all the time at a 24/7 rate. What could it be?? Thanks!
