My Dodge Neon is blowing white smoke out the exhaust. Can anything cause this other than the obvious?

Question

I am hoping it is not a cracked head.. could it be anything else?

Answer 1

I inspected and assembled the MRA (Modular Reservoir Assembly) inside the gas tank. It is a very rare design in only a very few vehicles.
Many people were getting laid off and they knew their employment was coming to an end. Therefore, their last few days were care-free and spiteful in some.
The MRA adjusts the fuel/oil mixture to your engine as it also tells you how much fuel you have in the tank.
Many defective parts were 'allowed' to pass the inspection process because many employees were getting 'revenge' for losing their job.
So, it may be as simple as the small (but very complicated) box inside the gas tank.
Let me know if that was the problem. If it is, stay away from Cobalts also. They have the same MRA inside their gas tank.

Answer 2

White Dodge Neon

Answer 3

sorry to say but it is either a bad head gasket or a bad head (possibly cracked) Dodge neon's aren't a very good car. I'm a dodge person and have dodges all my life but the neon is what they say is a throw away car.
they get about 150-160 thousand on them and they are ready to get rid of. it's not so much the neon but the engine they put in them. and they will go even faster if they are hot roded.
a few questions to think of is; has the car gotten hot lately or ran low on water?
was the coolant and thermostat changed regularly? was the car driven recently by someone who may of raced it or hot roded it?
these are a few reasons why a car may have a bad head or bad head gasket.

Answer 4

Unless you ran the engine really hot and cooked it, the head is most likely not cracked.

This is a common problem on the Neon 2.0 and 2.4 engines. I have fixed quite a few of these jewls. Most of the time, the problem is caused by the cylinder head warping. Remove the clyinder head and take it to a machine shop. They can pressure test it for you and exclude it being cracked. If it isn't, have them resurface it.

Answer 5

Sounds like your pistons rings need to be replaced. They are letting oil get into the cylinders. Or it could be your head gasket cracked alowing oil to get into the cylinders that way. If it was blowing out black smoke it would be flooding out a little. When oil gets into the cylinders, the motor burns that oil which will cause white smoke.

Answer 6

Bottom line, you need to have someone who knows what they are doing to inspect it and run a few tests. Then the head will most likely have to come off and be checked. My guess is that the head gasket is blown. This is an easy repair. Have your mechanic run a compression test and air up the cylinders. If the radiator starts to show bubbles during the air up your head gasket is blown.

Answer 7

Pull the spark plugs and check for presence of antifreeze (green residue). It doesn't have to be cracked head - blown head gasket should be enough but you won't know until you pull the head or at least look into the cylinder with a borescope.

Answer 8

You have coolant getting in to your engines cylinders and burning it off inside .Take it to a shop and have it looked at . You might get lucky and need a head gasket replaced , not lucky the engine block is cracked. And Car Man shouldn't generalize about the answers as he doesn't know I'm a mechanic.

Answer 9

It could be burning copious amounts of oil, but I doubt it. Put your palm close to the end of the tailpipe. Does water vapor condense on your hand and leave little drops? If so, you need a head gasket at the very least. If not, it may be burning oil, which could be even more costly.

Answer 10

Sorry, white smoke always means water in the exhaust. That can be cracked heads, or leaky intake gaskets, or (providing it isn't continuous) just water vapor that collected in the heads, mufflers and pipes.
