Car keeps running out of oil?

i have a montero sport that drinks up a quart of oil in a week. It has over 100k mi. on it. And i'm using 10-30 oil. Any idea how to fix it?Car keeps running out of oil?
Blue smoke is an indication of the engine burning the oil either past the oil rings on the pistons, or in the cylinder head iteself. In the head there are oil seals on the valves that may be dry rotted and the oil seeps past the valve into the cumbustion chamber. Only thing to do is a compression test and cylinder leak down test. Determine where the problem lies, and then remove and repair.


Costly jobs no matter what.............good luckCar keeps running out of oil?
Sounds like faulty engine valve guide seals and/or a blocked PCV (positive crankcase ventilation) system. Also check for a cracked oil pressure sending switch.
well obviously your oil is leaking, it could be leaking from ur head gasket which isnt too pricey to repair, if its leaking from the bottom thats g onna cost u a lot man
Either your valve seals are cracked/missing, or you have bad piston rings.





Valve seals can be replaced with the engine in the car, but it's tricky...piston rings means you'll need a rebuild, since the engine needs to come out to do it anyway.
the oposite
It's either leaking out of somewhere or it's burning off. Look for either oil stains on your driveway, or sniff around for a burnt refinery aroma. Determine which of the two is happening first, come back online here, let us know, and we'll procede from there.
Need to find out if your leaking oil or burning oil. If your burning oil then you rebuild the engine.


If your leaking it then find and fix the leaks.
find out where the oil is leaking from and fix the leak. If it is not leaking..the engine may be worn out and allowing oil to pass the piston rings
the blue smoke is your oil burning,,you have high mileage,,id suggest a tune up..it wont help much but it will increase your life,,your car has to many miles for it to be fixed,,probably your rings or valves,,,
there might be whole that makes leaks
Sounds like the valve seals have had it. This usually happens from not changing the oil regularly. I feel no pitty for people that don't change thier oil. Dump an oil additive like Restore or something into it. If that doesn't help then you'll need a head job to fix the problem. Look into getting a new ride soon.
park over some card board, check for leaks, it could be a leaking seal, or bad filter, take a peak under you car. it would definately cost you less to go and buy a year and model manual of you vehicle, and the parts to fix it from a auto store tahn to take it in. but find out if any of your buddies or family can help you too if you have little experience. that will save you having to buy a butt load of oil every week, better for the environment too.
sounds like a really big oil leak to me or u might have a bad gasket ... try going to some dealer or mechanic and tell them whatthe problem is and see what they say
