help: oil is dissapearing

[ractive_roLLa]

i got a 1994 corolla w/ 189,000kms on it
3000kms ago, i did my oil change i use mobil 1 10w30
a week ago i checked my oil and it was low.. so i put a bit in (only about 200ml)
today i check the oil level and its LOW so low that its not even on the oil stick anymore! wtf is happening, no leaks to what i can see...
milage on the car is great i got 175kms off of 13L of 87 octance last week...

n e suggestions on what i should do?
thanks in advance

is it coming out the bottom?

edit oh you cant see any leaks that probably means the seals around your pistons are out

[toyotaspeed90]

possibly leaking at the distributor, the oilpan.... or you're burning it

[89molavi]

check your pcv valve

Check the compression in the cylinders. Should tell you alot.
If the PCV is sending out oil with the fumes, its most likely that you have messed up pistonrings.

[homeguard]

ya there are additives you can try to fix this.

[ractive_roLLa]

one thing for sure, no oil is coming out of the PCV valve, there's no smell of burn oil or gas or fumes...

fuck, piston rings?

edit.. wait..
i donno if its the piston rings b/c i still get great milage, no black smoke coming out of my exaust and no gas/oil fumes from the engine bay

well, another you can check is you Tranny fluid too.....its possible your crank seal be blown or worn.... on the tranny side.

if your tranny oil turned brown, possibly that.

you do drive Auto right mike?

[Peter]

[ractive_roLLa]

ahh

trddragoon (itchy right?)- its Larry btw... lol (actually my bro's name is mike haha) yea its auto =/
ill check my auto tranny fluid asap..
thanks

i dont think im burning oil b/c the smoke isnt blue or black.. and it doesnt stink either

[TRDragoon]

^oops larry.....i keep on callin you mike

Could be worn valve guides and valve guide seals.

[ractive_roLLa]

whats a valve guide??

i just checked my tranny fluid, its still red, not like red when its brand new but there's a mix of brown also, nothing surprising it is? b/c its used and old...?

[Fabius]

from what i gather your burning oil...
turn your car on and go look at the exhaust fumes if its blue go kiss a shoe, your burning oil.

I really cant gather where else your oil could be going if theres no leak stains or what not.

[Flashmn]

There is one other place, the distributor cap seal. You might not notice the leak, because it leaks ontop of the tranny.
