hey guys need help here .. my car is smoking white i know that can be from head seals or piston rings.but how do you exactly which one it is.. before taking the motor apart ..
the car seems to smoke when i let off the gas pedal.i just bought the car b18c1 anyways the motor pulls hard no lack of power here

 

Leakdown test.

 

white is coolant not oil just saying

 

You MUST provide all pertinent information about your car and engine. Failure to do so may result in thread closure.

 

done

 

do a leakdown test and compression test.
you may have a blown headgasket, because of the white smoke.
pretty sure bad rings/seals is blue smoke from oil.

edit: just saw your edit. "no loss of power" so probably not a headgasket

 

Thanks. What car?

 

There was no loss of power when my wife's hatch blew it's headgasket.

 

oh well thank you for informing me.

 

yeah blown headgasket doesnt always loose power

Check if the Coolant has exhaust gasses in it

or check if the oil is milky



also is your coolant slowly disappearing and there is no signs of leaks?

if you have no milky oil or disappearing coolant u can get the tester like in the DIY i posted from autozone thats how we determined my SVT headgasket

White smoke is burning coolant usually the first sign of a blown headgasket

 

This is 94 eg with gsr .ctr cams and pistons

Also if it was a headgasket wouldnt that mean that the car would over heat?cause my car runs cool
Also oil is not milky

 

Smoking under vacuum like you're describing is usually from bad valve seals.

 

not always did u put the ctr pistons into the block or did u buy it that way cause if the stock headstuds were reused that could be ur problem

 

Yeah i bought the car that way.and notice it smoking on the way home gee lucky me

 

Anyways i plan to do a leakdown test thanks guys

 

No. There are no set sign of symptoms for headgasket issues. My wife's hatch also did not overheat.

 

So true. It's one of the more complex diagnoses to make on an engine as it can manifest in many different ways.

 

I'm curious how you knew it was a blown headgasket then. Did you just see white smoke and then do a compression and leakdown test? And/or see oil in the coolant?
