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.

First stepwould typically be to replace the PCV valve. It's located behind the valve cover at the bottom of the rubber tube that connects to the back of the valve cover and branches off to the air filter housing.

Alternate possibility:

If the head gasket has been replaced, it's likely one of the oil returns is blocked (replacement head gaskets, for whatever reason, don't usually align with the head correctly). The solution is to open the secondary oil return. I used a one foot piece of 4 gauge bare copper wire (more of a 1/4" copper rod). Remove the valve cover. Taper the end of the copper wire to a blunt point and drive it about 6 inches down the oil return on the backside of the head near the rear of the head (directly behind where the oil filler cap was).

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.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

There is white smoke coming out the tailpipe no smell of antifreeze


If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

Lots of back fireing. does not run fast, white smoke


White smoke is generally a sign of buring antifreeze which is a sign of a blown head gasket. Pull your oil dip stick and see if the oil is milky white. Open your radiator cap and start the truck. Do you have lots of bubbling going on or is there a oily residue in the antifreeze? If so these are other signs of a blown head gasket.

Grey smoke coming from exhaust and oil in the exhaust pipe


Grey or blueish smoke indicates that you are burning oil, usually a sign of worn piston rings.

Keep an eye on the oil level in the vehicle

MY 2000 MAXIMA IS HAVING LOTS OF ISSUES


Your antifreese is leaking through the engine block The white smoke that you see coming out off the tail pipe is steam from heating up the antifreeze. This problem needs to be taken to a mechanic because your engine may have a blown head gasket or a cracked block. You keep having to fill it up with antifreeze because it is evaporating inside your engine block. Check your oil and see if the color is like a white milky liquid. If so then its definitely your head gasket. Try not to run the car to much like this because you will crack the engine. This is a pretty expensive job. You may want to consider a different vehicle because who knows what else will go wrong with this vehicle. I hope this helps you.
