I just bought my mk3, its got about 50k on engine and tranny, its BURNING through oil tho, i dont think its leaking, but its drinking a considerable amount, whats up with that bad piston rings? And ive been wondering what should my oil pressure be its around 13-17 pounds per thousand rpms, how much pressure is to much? advice appreceated, Any tips on maintaining my engine that only a supra veteran would know?
just wondering...

- Start date
i havent done a compression or leak down, but when i take the oil cap off when the engine is hot i can see smoke coming out...
Some smoke is normal but if you connect a manometer there you'd know a lot more. A compression test would help too. Btw the engine will run out of tune with the oil cap off. Pirate air...

Bad valve stem seals seem to be common on the 7MGE. You may want to start looking into this. My little bros Supra burned almost three quarts of oil in two weeks of driving and blew up his motor. Does it take awhile to start the car in the morning? If so, this may indicate bad valve stem seals. Whatever you do, DO NOT let this motor run low on oil - EVER, Good luck!
ya the first start of the day allways takes like 3-4 extra seconds to turn over.. Ive been obsessivly checking my oil like 2 times a day, its wierd tho it hasent seemed to have lost any oil in the past 3 days, cince i changed over to royal purple...
when i try to turn my car over in the mornings or after its been sitting for a while it takes a couple of tries. sometimes i have to give it a little gas to get it to fire, and when it starts i get whitish-gray smoke out of the tail.
anyone have an idea what could be going on?

like someone previoulsy posted, id bet a bad valve stem seal(s), or piston rings, i think white smoke is coolant, and black is oil, id say smoke on startup would be oil left in the cylinder being burnt off on startup, have a compression test done
