If you are sure the oil is burned then the only way to fix that would be to refurbish the engine - it will be a long and expensive job.

Burning Oil

we check oil every other fuel fill up. on old cars, every fill up
did you run car 10,000 miles to a oil change? unstated.
1qt/3000 miles is perfectly OK.
so 10000 mles is 3.3 quarts burned and off the top of the dip stick
if you drive fast, it burns more, got a heavy foot, or load in back>?
if you had done it right, you'd have already learned YOUR engines
consumption rates, and learned to check when IT , needs checking
we do this on all engines. all machines.
all engines burn oil, the exception , a church car, new, and never driven, far, or fast or for 10000 miles to an oil change.

your mech, was right, he was thinking , you dont check oil?

I have a 79 jeep cj5 with a 304 and im getting alot of white exhaust smoke after the motor warms up rebuilt the carberuter new plugs wires cap rotor and new coil

White smoke is often times the result of "oil burning". What happens is that instead of the oil control rings on the pistons pushing the oil down into the oil pan, these rings over the course of years become pugged up, as a result the oil control rings "fling" the oil onto the spark plugs causing the oil to get partially burned off in the combustion process causing your simptoms There is only so much you can do to stop this. One thing you might try first is go to the automotive store and buy a crankcase cleaning system. What this does is cleans the inside of your engine including the pistons rings and washes all or most of the gunk in the engine into the oil pan. WARNING: excessive gunk in your oil pan can clog your oil pick up tube depriving your engine of oil, this will cause it to seize up leading to your last resort in fixing what might be your problem, rebuilding the engine. Make sure to follow the manufacturers guidelines when using a crankcase cleaning system.

I have a 2002 jeep liberty with 145,000 miles. I change my oil a month ago and check the oil today and notice i was a half qt. low. I notice oil building up around the intake manifold (left side). I have...

THis could be bad gasket or just bad seals. I would recommend to have the engine washed on your local garage or if you can do it on your own the better. Once cleaned you should be able to identify the source of the oil. Usually bad gaskets would also cause you to burn oil and cause smoke.

Well long story very short. I over filled my oil in a 2001 Jeep Grand chero. It happens to burn oil on a regular basis. What will happen?

Generally if it's less than a quart overfull, nothing will happen. Since you are consuming a lot of oil, the level will drop with time.
If more than a quart, remove the oil filter and drain it (may take a couple of times, starting the engine each time to re-fill the filter) or simply drain the oil from the engine into a clean pan and use that oil to re-fill but not as full as before. Having too much oil in the pan can cause the crankshaft to froth up the oil like it's in a blender which causes air to get into the oil (air does not lubricate anything) That, can damage the bearings on the crank.

Why does the "low oil level" light come on every three months or so? I take care in for an oil change and mechanic says it is normal.

Your mechanic is right. If you only fill to the bootom of the fill stick which actually better than overfilling. It seem as the oil gets hot some of the chemicals will evaporate but this will only occure if your putting like a 1000 miles a monthe in which case its time to change the oil anyhow. Full synthetics oils will go twice as long without breaking down. Its just good technology catching up to itself.

Engine smells like rubber burning and temperature gauge at normal temperature. Water/coolant leaking out of reservoir and needs to be filled ever 2 days. Oil level is normal, but when it's hot outside the...

Generally that smell is caused by an oil leak that is getting on either the exhaust pipe or manifold (doesn't take much to smell). As far as bottle getting low, I've got a 93 that never stays full but only needs coolant in the radiator about once every two months. Been like that for two or three years and has never overheated. I'm sure there is a small leak somewhere, but I'm not driving myself crazy looking for it. Check all hose connections, and look on the ground after being parked overnight...If it's leaking, something will show up. But if the radiator is staying full, just check it when checking oil level.

Oil in radiator

There is really only one thing that causes this, that is a leaking cylinder head gasket(s).
