Having a lot of oil loss in my
1993 c1500 5.7 TBI
No leaks on the ground. Had exhaust smoke which I originally thought was Valve seals which I’ve since replaced.
Exhaust is no longer smoking but I am seeing similar oil loss. I have to add around 2 quarts every time I fill up at the gas station.
I’ve seen some threads about it being possible PCV related and disconnecting my PCV hoses I can see there’s a good bit of oil in the vacuum hose.
How do I diagnose and fix this?
Thank you,
