Ok, i know i hear it all the time…this car just burns alot of oil. But right now i’m at half a quart a day and its not even my daily driver! I know what your thinking … bent valve or bad rings yeah. ive heard that too. However, the car runs just great. I’ve gone over just about every inch (other than engine rebuild) since i got the car and it seems that if there was a catastrophic failure inside causing extreme oil burning the car wouldnt be running so good? Also i know the previous owner did work on the head as well as disassembled, cleaned, did a valve job w/ cams and replaced seals and 7 bad rocker arms (within last year or two). So i put the internal engine things that i cant do much about aside for now. I replaced the PCV valve as it had signs of oil in that hose. The pcv itself also was rattling when i replaced it so i figured maybe it was allowing oil to pass through during operation of the car. I also have recently gone from using 10w30 to 10w40 to see if that makes a difference. Im going to run it a few days and keep track to see if im still around a half quart a day. if so, i will likely use some kind of oil treatment (lucas) in hopes that it will seal up wherever oil is passing through. Does anyone have any other ideas that i could try or signs i could look for before doing something drastic like an engine rebuild (or engine swap)? I really am happy with how the engine is running other than some very faint backfiring or rumbling in the exhaust (probably since i dont have a cat). I appreciate anyone’s ideas they can share. thanks.
