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?

Here's some areas I've replaced leaky seals: Oil pump, cam seal, crank seal, rear main seal, valve cover seal, and valve seals. Thing is, most of those you can trace to the leaky source so if you can't I would imagine it's burning oil internally...but you said no blue smoke so that's kind of weird.

Valve seals will blow blue smoke too but usually just at start up.

Also when you say barely a quart of oil in the engine when ready for an oil change, do you mean there's barely any on the dipstick? If that's the case, that's only about a quart worth of loss. If your engine didn't have any oil in it, it would surely die in minutes while running.

No, not dipstick. i change my oil every 3000 miles. when i drain the oil pan there's little bit of oil.i feel its a little less then a quart. When oil is just changed car is smooth. As it gets closer to oil change it sounds like its gasping for air when accelerating in 3rd/4th gear. All in all I am just going to change the rings and monitor the oil consumption.
