94 celica burning oil? Options

[Crazy0reo]

hi, have a 94 st, its my DD. Recently I have noticed between oil changes the car burns oil. There is no black smoke coming from the engine or the tail pipe. When it comes time to change oil, there is barely a quart in the car. Anyone have any idea whats the cause of this? Car runs good no problems, also no leaks. Odometer reads 190XXX. Any ideas?

Your motor is junk. St's are known for eating oil when higher milage. My buddy works at a yota dealership, they Dont even recommend re-ringing it, just total motor job. You could try if you or you know someone with awesome mechanical skills, but that's a lot of work for a short life unfortunately.

I dought valve seals would leak this fast but also possible. St's are almost always rings...

They make a specialty chemical you can add to your oil to de-gloss your cylinders. Takes a while to work (500 miles?) And then it can slow it, but not stop it (experience, also never heard anyone say it completely fixed their problem.) But you must be having some type of smoke problem. Might be hard ro see it in winter, but that's quite a bit to loose.

Pull off your air intake from your throttle body. See if there is any oil in there as well.

I think you jumped at that whole "you're engine is ****ed" thing a little too fast bucko. I've got 180k miles on my 5SFE and the rings are fine. The valve seals leak a tiny bit and it puffs a little smoke when you first start it after it sits in the summer. That's it. It's enough of a leak to burn a quart every 3k miles so I haven't worried about replacing the seals yet. I wouldn't doubt he has the same issue. If there is no constant black smoke, I doubt the piston rings are shot. You lose a lot more oil and will notice a lot more noise if that's the case.

A seal job isn't that hard. You put compressed air into the cylinder to keep the valve from dropping (if it does you're going to have to take the head off), take the spring off and just replace the damn seals.
