My JDM H22 blows white smoke when i stay in vtec like i hit vtec then let go and punch it again and it stays in vtec and then white smoke blows out.

 

your headgasket is probably blown.. check your coolant.

if your coolant is low than take of it ASAP.

 

yeah maybe the gasket. what do you mean by coolant, antifreeze?

 

yup, same thing

 

the same thing happens to u

 

Check your oil for coolant in it.

 

doesnt white smoke mean burning oil? maybe its bad rings....

 

white smoke is coolant
black is fuel
blue is oil

 

na no antifreeze in the oil.

is your coolant full?

 

yeah i think so

 

how much smoke is it? like a real lot or like as much as when a car warms up

 

I thought black smoke was Fuel System Failure. A little bit of white was slight oil leak, a lot of white smoke was really bad oil leak, and blue smoke was coolant leak?

 

my car puffs a little black smoke when I rev it high because I'm runninga little rich..

 

same symptoms of my car,yep you guessed it blown head gasket.
good luck

Get more information!

Is your car overheating, tell more about some actual signs of what beyond the white smoke is going on with the car.

 

well theres no overheating. But when i rev it i think very very little or nothing of white smoke. Only when i hit vtec then let go of the gas and i stay in vtec and then let go of the gas then punch it again then a lot of white smoke comes out.

have u done a compression or leak down check yet?

 

It might not be a headgasket: it might be a cracked sleeve. You can check the inside of your valve cover for the infamous "head gasket icecream" that tends to develop wherever coolant and oil are being churned together...it's simple and an effective way to determine if you're burning water or antifreeze.

 

na i havent done a compression or leak down check yet

do those before u rip anything apart

 

alright ill do them then.

 

symptoms of the blown head gasket on my car
1.oil residue in coolant reservoir tank
2.blowing white smoke under heavy accelartion
3.smell coolant after driving,but nothing leaking
4.foam in radiator
5.no overheating

hope this helps

 

oh alright thanks. Ill check that to. On mine u can smell gas on heavy acceleration sometimes and a little bit but may be its my bendy thing thats mest up and probably has a hole that connects the straight pipe thats why it sounds like its open header.

 

I checked for all the symtoms but none of them accept the white smoke. Theres no water in the reservoir i guess it went in the engine i dont know but i filled it up with antifreeze and water to the minimum and added antifreeze to the radiator to the top. I needed some more to fill it up to the top.
