Oil out the tailpipe is definitely oil control rings and all the rings on the pistons simply worn out from high mileage.If keeping the vehicle,a remanufactured engine would be the best choice,with a good warranty.A used engine is also a possibility,but sometimes hit or miss.A rebuild would consist of about the same cost as a remanufactured unit.To correct only the oil problem would consist of a complete disassembly of the engine.The block would have to be taken to a machine shop and overbore the cylinders whatever is needed,.020"-.040",and purchase new pistons corresponding to the overbore,and all new rings.Top compression ring,secondary compression ring,both oil control rings,and the oil control expander.This will correct the oil out the tailpipe,but you are at a full on rebuild at that stage.

On my 2003 dodge stratus se sedan 4 cyl dohc.. Car started overheating and also blows cool air when heater is on. I just changed thermostat and refilled antifreeze and iwhen tested was blowing hot air...

Did you check to see if you have water or anti freeze in the oil? You could have a blown head gasket. This would be why you are adding fluid so quickly. let me know.

I have a 1998 dodge stratus. 2.4 L 4 cyl engine. smoke began coming from the back aarea of engine just in front of dashboard; radiator full. not running hot. oil level ok. no leak. no light indicato

Could be oil dripping from the valve cover onto the exhaust pipe.
One drip can cause alot of smoke when it hits the pipe.
Could be power steering fluid too.

I have a 1991 d150 p/u and it has blue smoke from exhaust when started

If it smokes more when you first start it than other times, the common cause is leaking valve guides in the cyl heads.
The guides leak oil into the cylinders when the engine is not running.
Most other causes would make the engine smoke when running or under load too.

3.8 grand caravan 100000 miles. Uses 1 qt every 1500. 5-20 as suggested by manufacturer. Is this excessive?

I would say YES......Try buying a can of RESTORE. They make it in 4 cyl,6 cyl ,and 8 cyl . Each can is a different size. I have used this product ,and it hlpes. doesnt FIX,just addresses problem.Slows CONSUMPTION greatly.

I just bought a 96 dodge caravan 2 days ago ive drove 150 miles today and when i went to shut it off it had smoke i raised the hood its coming almost directly from the front of the van i went to leave...

How low was the oil? It could be something as simple as some oil is leaking out of the valve covers and once it hits the exhaust manifold then it starts smoking. Usually smoke coming from the engine compartment is a result of that. Look and see if it leaks any oil while you have it parked in pavement for a while in case it has something to do with the oil change.

Good Luck

Oil consumptiom

Figuring off of national standards thata gasoline engine is allowed to burn 1qt. of oil every 2,000 miles tthey would be correct.But That is not to say for that particular engine providing that oil has been changed every 3000 miles,There could be other problems contributing to your car,for instance cklogged pcv valve,leaking injectors or fuel preasure regulator both can cause fuel contamination to engine oil (Dillution) Thins oil too much,or overheat condition,or failed cat convertor.With this in mind talk with another Nissan dealer if only by Phone.
