SOURCE: ok, I'll rephrase, car died at 2500 rpm, engine shut down and oil

A blown head gasket can let oil + water into the cylinders. If this was the case, it's probable that you've bent the cylinder arms (don't know the technical term) but if that's the case, the cylinder(s) will not rise to their full extent, thus lowering compression.

We everything from crankshaft to timing belt. It started burning oil at about a quart every 2 weeks, now it will start but stalls aafter running about 10 minutes. Now what can be wrong with it?

You should have a compression test done. It will tell you the condition of the rings and cylinders, which I bet are in poor condition if the car is burning that much oil. Move on to a leak-down test if the compression turns out OK.

A direct answer to your question, you have internal mechanical damage to your engine. Doing the above will tell you what has failed.

Loosing oil no leaks no oil splatter on motor

Either it's leaking into your cooling system due to a blown head gasket, or you are burning it (oil) due to engine wear such as worn valve guides or piston ring/bore wear. Have a compression check done. (By the way it's losing not loosing) Is the exhaust very blue in colour? that indicates burning oil

Burning oil ,no leaks or smoke

how many miles?
can be bad rings.
or bad valve seals.
or both.
do a compression test then a leak down test, and bingo the answer.
if both pass, the valve seals are bad.
if not rings are bad, if the oil test for compression fails the valves them selves are bad, if the teaspoon of oil test , passes the rings are shot.
read up on all compression tests. using google, or by any car engine book, one that tells you how to test for this.

The leak down test, can even tell you which direction the leak happens
using a rubber hose to your ear.
i can hear air leak to crankcase, valve cover oil filler, oil dip stick hole, and to intake plenum and even hear it at exhaust ports. sure can.

one the oil control rings on old engines can stick down and be
near useless. stuck in the lands. seen many like that.

Id use the 2 gauge to judge engine condition,
if bad, its hopeless. (bottom end bad)
if good, all tests. then the valve seals are bad.
there is a way to change them head on car.
using shop air , or other wild tricks.

My montero sport is burning oil what the cause.?

Could be worn piston rings letting oil into the top of cylinder from below, or worn valve stem seals or valve guides letting oil in from above.. A shop could do a compression test or a leak-down test and give you a good idea of the engine's health. Low compression on any of the cylinders means the rings or valves are not sealing well, and could let oil in to burn. Either of the tests could point to the problem, but a leak-down test is considered the more accurate test
How much is burning? If you are burning more than a quart every thousand miles, it is a problem that needs attention. Most car makers say a quart every 3 thousand miles is not a problem and may be considered normal, although owners may dispute that as they often do. Some engines just seem to lose no oil between oil changes, but most do use or lose a little oil between changes, it is normal. If your oil consumption is on the high end, have the test done. If your rings are good, a cylinder head job (for the valve work) is much less expensive than an engine rebuild.

My vw golf 1.6 2002 plate burns to much oil it has a high engine pressure and it's burning a lot of fuel. It also produces a high amount of smoke or a short period. It has only done 70000 miles. I noticed...

Typical worn engine symptoms. The oil burning and smoking is most likely the valve stem seals gone hard and worn allowing oil into the cylinders when running.

They can be replaced insitu by most shops without removing the cylinder head.

White Mayonnaise on the oil filler cap and in breather pipe is often from engine always running too cool or many short trips....under 5 miles. Coolant temperature should be 85C and above after a mile or two.

If the pistons are worn, a used engine would be best bet..

In order to know how worn the engine is the engine needs a compression test and a leak down test. if the shop you take it to does not know what a leak down test is, take it some else.

Compression pressure should be even on all cylinders and around 130 to 180 pis.

A' leak down test' is putting air into each cylinder with a special two gauge tool and measuring the cylinder air loss in percentages. Good engine will be 5% to 15% loss. Bad engine will be 25% and above.

On a diesel engine the percentages will be the same but compression will be 400PSI or better.

1997 silverado 5.7L I am going to replace the intake gasket because it is leaking. It is buring 1-1/2 quarts of oil or more between oil changes. I suspect a vavle job may be in order but have never done...

Bad valve's will not burn oil, bad valve will cause a cylinder miss fire, due to you will loose cylinder compression, I would replace the valve seal's, Also do a wet and dry compression test, do a dry test, and write down reading's, then add oil in cylinder, and do another compression test, if in any cylinder's compression jumps higher then dry test, that's where your loosing oil, weak piston ring's.

My 4 door jeep is sucking oil way too fast i dont know whereit is going. now putting synthetic oil in and in 45 days i had to go and get more oil put in. it is not leaking nor burning so where is it going

Using synthetic will not help, save your money for now.
If it is not leaking, it has to be burning. Get a compression test done, and possibly a leak down test, to get an idea of the ring condition and valves. Also, how does the coolant look?
