I have a 93 pickup with and 22RE engine and I have to add a half quart of oil a day. Engine does not drip oil and the exhaust smoke is clear.Does this sound like the piston rings.Had new cylinder heads replaced last year other than that the truck runs strong and no loss of power. Other than a rebuilt motor should I just continue to add oil until it worsens.Engine just turned over 300,000 miles Does anyone have any advice? Thanks Joe
How long has this been going on?So are you getting smoke out of the exhaust or not?A compression test should be done.
Yea do a compression test .. That many miles proably your rings just giving up the fight a 1/2 quart a day is rather excessive consumption your spark plugs should show the evidence . . As far as coming out the pipe it will come out it doesn't have to smoke to do that . Excessive oil consumption is also hard on the caytlic converter . Might consider changing that when the rebuild is done .if you have a cat ( three hundred thousand . That's a good run)
Like mentioned it doesn't have to smoke to burn oil if the cat is in good working order it even reduces the chance of it smoking even more . Your spark plugs will tell you the answer . 300+ thousand miles will do that .
Hi everyone, bringing back an old discussion, my 93 22re has the same oil consumption problem, i drive 90 miles every day and and i have to add a quart every day. And just like Joe Barrios, there is not tail smoke, running strong and the spark plugs are dry! I rebuilt the engine a year ago, was running normal, i did put a breather in the front hole of the valve cover and couple months after that started the issue, would that caused somehow the excessive oil consumption? I just put the hose back on, and i will drive it to see if that is the reason, any info will be highly appreciated, thanks.
@Rafa Your problem us not like Joe Barrios'. He had 300,000miles on his engine and yours is rebuilt. At 300k miles, burning oil is not unusual, although 0.5qt./day is a lot. How many miles on your rebuild? Maybe it wasn't broken in correctly?
