Oil leak question - I have a 1999 Toyota Corolla with 196K miles that is leaking or burning oil. Its not dripping anything on the ground, its just all over the engine when you look from underneath the hood. When I pour in 3 qts of oil, it typically lasts only 700 -800 miles. Yes, thats correct - 3 qts of oil disappears after driving 700 miles. Oil level goes below the minimum mark on the dip stick and the engine oil light comes up. Since that episode, I now add some oil after every 400 miles so the engine is not starved of oil. I had recently changed the valve cover gasket and the pcv valve and there is no leak from the top or into the spark plugs. Also am not sure if this leak is from the Rear Main Seal or the oil pan gasket. Given its an 20 year old car, I dont want to spend lots of $$ hence was wondering if there is some other cheap alternative. Also given the oil doesnt leak on the ground, it may be possible that the engine is burning oil, though I dont see any white/blue smoke coming out of the exhaust.

The car runs perfectly well, except this oil consumption issue. Any help will be appreciated.

oil doesn't leak on the ground, that means engine is burning it mainly. Just live with it, engine is wearing out

Had a 2000 Corolla. Burned 1qt every 500 miles. The pistons get sludged up and carry oil onto the combustion chanmber walls and it gets burned off. 1ZZ-FE engines are known for that if you dont change oil every 3k miles. Try engine flush? Marvel Mystery Oil? I used Marvel and it slooowly made it better to about 1qt every 800 miles
