Brought my beater in because car is lossing oil roughly 5 quarts every 700 miles and no puddle anywhere.
There’s leaks around the cap and on the engine cover. Also on some of the parts as i assume it’s probably leaked 50+ quarts.
I did change PCV valve and that didn’t do anything. There is a massive blow by from the engine. And the tailpipe is a little black but if it’s burning a lot of oil it should be worse.
I thought potentially the valve cover was really bad but to much oil for there to be that of a massive leak according to the mechanic.
Where do I start diagnosing next.
