Question about 1994 Cadillac DeVille

Smoking out of the tailpipes

There is smoke pouring out of the tailpipes, but I don't think this is a head gasket problem, because it smells like gas, not coolant. The fuel injectors look clean. Any ideas as to what may be causing this?

I have a 99 chevy blazer it smoke when you give it gas it dont smell like oil no water is coming the tailpipe it is a strong smell of gas


Sounds like a bad head gasket. This will need to be replaced soon if its bad enough to be smoking. One way to find out if this is the problem, is to look at the oil filler cap, if there is corrosion, white residue, or water, you most likely have a bad head gasket. Also check the oil thru the dipstick, if it looks
Like theres water or antifreeze in the oil this is also a sign of bad gasket.

My 99 dodge caravan drove it today and it barely would go and was smoking what could it be


First you need to be sure if it is smoke or steam..Set parking brake ..,Get safety glasses .and safety mask for breathing..Is the smoke from the tailpipe or elsewhere ..,or is it smoking everywhere..?..Is it leaking anywhere.How many miles are on the van and what engine size..?..Make sure engine is cold for safety..Check coolant level...You can smell the coolant mix if it is steam...If it is smoke you can smell burning oil/fuel combination...If it is steam more than likely it is the head gasket and or possible cracked head or block in worse conditions..Some head gasket failures can leak outside of the engine .however it is rare...Check oil level and see if coolant/h20 mix is mixed with the oil...If it is it should show nasty color and or appear to be overfilled considering how long the failure has happened...If it is smoke it can be a few problems....valve seals..,clogged catalytic failure ..etc...Please send more info if possible And I will guide you through troubleshooting your system.....Thanks..

Sounds like you have a blown head gasket and coolant is getting into one of the cylinders.

No power when I step on the gas and is smoking bad


Smoke from tail pipe or smoke from under hood?
A general rule of thumb if it is coming from tail pipe the color of smoke will tell you a lot.

White and thick means head gasket failure, Blue means oil is being burned.

I would recommend you check the seal of everything and make sure it is cleaned that had to do with vacuum or fuel distribution. EGR valve (gasket fails sometimes) IAC valve, MAP and MAF sensors, Fuel injectors, FPR (this will need replaced if leaking),

Also check you coolant and oil look for signs of either one mixing with one another, smell you coolant and make sure it don't smell like gas either, look around where the head meets the block and make sure you don't have any coolant leaking there. The smoke if from the tail pipe makes me think head gasket and these are simple checks. They are not 100% diagnosis but can lead you to the problem.

Also one obvious thing would be make sure no one put anything in your gas tank.

I would most likely look at the injectors first then the head gasket next.

Smoking thick white smoke from tailpipe


  • A little is to be expected when first starting an engine.
  • White smoke coming out the tailpipe more than just a little at start up means is that your engine is burning antifreeze. Usually a head gasket leak, cracked head or cracked block.
  • I know this is not good news but please don't "shoot" the messenger. I answered this question so you would not be stuck somewhere with a seized engine. Which is what is going to happen in the near future.

Hi guys, I recently bought a 94 Toy Camry (4 cil, 2.2 engine), and changed the oil and filter. Passed smog check OK, but after only 40 miles of driving, the oil arose above "F" lever with about...


Hi and thank you for using fixya:

I would like to start by asking you several questions:

1-how many miles on the car?
2-is the car smoking through the tailpipe?

If the car is smoking there is a possibility of having bad piston rings although it is very rare for the gas to pass down the cylinder.

Gas smell in exhaust


you have either a blown head gasket or cracked head. The white smoke is coolant passing through the engine and exhaust. The gas smell is from compression leaking past the gasket or head, pushing fuel vapor into the air.

2005 325i with a lot of white smoke coming from the tailpipe.


Yes, the best way to determine if you've blown a head gasket, it to use the diagnos # 4 gas analyser or smog test analyser- (the tube that goes up the tail pipe), place the wand near the radiator. if the wand reads finds CO in the cooling system ,100% blown head gasket
