im low on oil but i still have oil in the truck but after i replaced my vacuum pump seals i got blowby from my oil cap. im doing an oil change this week but its just a faint fart of smoke. nothing big but you could barely see it.(you would have to look at a certain angel and it almost a whiteish smoke i dont know there isnt alot) i still have a little blow by on my blowby tube.
Main thing is: could i have ruined my rings from low oil?
My oil pressure is regular. 60 on highway 25-35 idle. 70 on cold start ip
