I have a 1999 z24(2.4 dohc) Chevy Cavalier and has been hesitating and whenever it does that heavy white smoke will POUR out of the tailpipe when I give it gas. But it only does it here and there.

    Don't think it's a head gasket because it's not missing coolant. Been using a lot of oil but I figured that was because it needs new valve cover gaskets. My dad works on cars for a living and said maybe an EGR valve or piston ring?

    Daniel OOps I mean Danielle, if going through that much oil, probable internal engine issue, piston/rings/valves, oil will fowl plugs causing miss and normally whitish blue smoke. If oil smells like it has gas in it, could be injectors faulty, flooding fuel into crank case, thinning oil allowing it to be burnt easily also. Regardless, would not continue to drive, have a good technician or your Dad have a look.

    It's Danielle, I'm a girl so it's not Daniel, lol. But the oil doesn't seem to smell weird, it's just low no matter how much I put in it. My dad isn't being much help so I'm trying to find someone else to look at it. The valve cover gaskets need replaced but my dad did say that wouldn't cause that much oil loss. It seems to start smoking worse every time I put oil in it.

    Sorry Danielle, for misspell, please do try to find somebody with knowledge to have a look. A compression leak down test can probably answer a lot of questions on where the oil is going. Have a good day.

    It's not missing any coolant really. It's used very, very little coolant at all since I had the coolant leak it had before fixed.

    It is using tons of oil though, I have put 4 quarts in it this week and it's still low.

    It has a brand new fuel pump and filter. I honestly don't know much about cars at all, and just recently started driving so I have no idea what to do or have done about it doing that.

You need to start by having a compression test done to confirm there isn't anything I ternary wrong.

    Ternary? Do you mean terminally? I honestly have no clue what a compression test is.

SOURCE: white smoke and a smell of fuel

The white smoke is from anti freeze. The smell of gas in your oil is probably from the same cause. I do beleive you did not clean the milled ares good enough before installing one or both of your gaskets. Just in case you did loosen one of the head bolts up for any reason....One bolt I do beleive on the right front bank of this engine has to be also sealed before re enstalling it for coolant will pass through it if not sealed

SOURCE: car is hard to start, keeps stalling, white smoke coming out of tail pipe

It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

SOURCE: smoke from engine

Is the smoke white or blue? If white means that you have a leak of water or antifrezze into the combustion chamber. If blue, replace PCV valve, and air filter.

2001 chevy prizm jerks when in gear heavy smoke out of exghuast

It will help Matt if you would have said what color the smoke is thats coming out the tailpipe. White heavy smoke will be antifreeze getting in the combustion chamber.Could be head gasket,cracked or warped head.Black smoke would be fuel system pumping gas in making it run rich,And not able to burn the fuel completly.

1999 saturn sw has blue smoke coming from tailpipe. I would like to know if it has anything to do with head gasket

blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage

White smoke comes out of tailpipe when driving, steady stream of water also. 99k miles

White smoke coming out of a tailpipe indicate water. Check your oil. Is it murky looking ? Is there an oily film in your radiator ? You may have one or more problems. Blown head gasket, cracked heads or water jacket.

Cavalier blowing out black smoke car idles fairly well considerin

Black smoke is usually unburned fuel. P0171 reads bank 1 system too lean. There isn't one answer. You need to dig further and inspect your cars fuel system, from the pump to the injectors. Because of the mileage you may want to start off with a compression test just to see where you stand with the motor. write back if you have any other questions.

Engine over heated and will not start

Did you have oil in it. depending on the severity of the overheat you may have seized the engine. You also could have a head gasket problem. The cooling system on these little cars can overheat in heavy traffic and going up a hill a little too fast. Solution? If it started and showed white smoke out of the exhaust. Head Gasket. If it won't turn over with the starter it's seized. Both will cost a mint. If you had no oil engine could now be junk.
