Blueish white smoke comeing from exhaust

White coming out the tail pipes is coolant/water. Doesn't mean the head gasket is blown, but you'll wish it was. Could be a cracked head. They can crack inside the intake or exhaust port. This would still give you a good compression reading. If in the intake, you would have a misfire. Exhaust you wouldn't. As far as the blue goes. It is mostly white in color, with a hint of blue color. Loosing that much oil would be a major leak or the rings are shot. Rings being shot, you would see that blueish tint in the smoke.

Coolant leaking on engine and burning

This widespread problem is the one part no one thinks of: ENGINE VACUUM PUMP.it runs mechanically off camshaft;once seal leaks,oil from camshaft housing enters vac oump and becomes ingested by engine,therefore exiting tailpipe,water accumulation in by product of catalytic converter changing smog/carbon to water/vapor.REPLACE VAC PUMP AND SEAL ,SMOKE WILL STOP!!!!

THe heat and air has nothing to do with the exhaust, It is either burning rich, burn your eyes? Or it is blowing steam out from a blown head gasket, check the top of the radiator for oil an check the oil for water. A radiator shop can do a comp check, do not let it over heat, it could go months before finally stop running. Check again and make sure it isn't a blueish smoke, It would be oil. Whole different story.

you're burning oil. Get a compression test done to it

Is the white smoke steam or water? If so it is a blown head-gasket. Fix ASAP or you will ruin the engine. Or is exhaust blueish/gray or gray and smells like gas or oil. If this is the case then it could be a fuel injector, spark-plug (or no spark to plug), valve seals, piston ring/s, or clogged air filter.

If you are sure it is white smoke and the car overheats or looses water,The head gasket is bad.
Or It's valve seals or rings smokes (but the smoke would have a blueish tint)

sounds like valve guids are wearing out.. drying out and cracking. only fix is to replace them. or try a heavier oil. sometimes that will help depending on the severity of the problem.

Blueish smoke is probably excess fuel. If this is the case, the exhaust should smell gassy. I'm thinking that one of the injectors is leaking...something injector cleaner wouldn't solve (you may have to buy a new injector if that's the case). I would check the spark plugs to see if one looks different than the others, that way you can narrow it down. I took my injectors for my porsche to www.witchhunter.com to have my injectors checked and found that a couple of them were leaking so bad they couldn't be fixed. If you send in your injectors to him and any of them are leaky/unrepairable, he won't charge you for them. :)

You will need to check head gasket. Please check the oil for coolant (milky deposition or presipitation). Also check if you loosing coolant and if coolant has oil in it.
Please kindly let me know if you need more info
Good Luck
