i just build up a motor and its burning out white smoke alot of white smoke out anyone have any clue what might be the cause?

 

Could be burning coolant.

 

white smoke means its running too rich.

 

no black smoke means running to rich white is coolant

 

You got a coolant leak son.

how do you fix it?

 

replace headgasket possibly

 

^^Yea, it's most likely the headgasket.

 

hi guys this is my first post so forgive me if i'm way off.
i had this problem on my car a few years ago and did my headgasket and still had white smoke pouring out of it.According to my mechanic it turned out that i had really badly worn valve seal which was basically letting oil pour through onto my hot piston.He then proceeded to show me by putting a few drops of oil onto my hot exhaust which surprisingly emitted white smoke.

 

whats the vehichle and its definetly not to rich if its white smoke

what if you just replaced the headgasket???

 

Hmmm...that's weird. I've never seen oil burning into white smoke, it should be blue if it's burning oil.

 

Not to be a dick weed, but did you replace it yourself? Could be done wrong, Hopefully it's that, other wise cracks in the block could allow coolant to pass through, hopefully not though.

 

What initially was wrong with the motor?
If it overheated,it could be still a few problems.
Intake could be leaking,cracked head,or block.
Someone could be pulling a fast one on you too"if you know,A good practical Joker"
A few feet of vaccuum hose,and a bottle of ATF would have someone puzzled,But Probobaly Not your problem!

Start with the simple things first,make sure of no cut corners

 

By the way!

Blue smoke=oil

WHITE SMOKE=coolant

Black Smoke=fuel

 

i now stand corrected. (what a dissapointing first post. )

 

well..... the white smoke from coolant, and the blue smoke from oil are very close in color. However, the smoke from too much fuel is very distinct. So your first post wasn't off base

 

u definitely have coolant gettin into atleast one of your cylinders...could be head gasket, a cylinder could be cracked, the head could be warped or cracked. you could try a cylinder leak down test to see if you're loosing pressure through 1 or more of the cylinders. basically you would get the kit and you pump air into the cylinders and see which one leaks down. its not supposed to leak much at all. that should atleast help you figure out which cylinder(s) it is.
