hey, my ex runs ok for now, but iv been seeing white exhuast coming out, not so much that you can see it while you are driving but enough where if ur behind me you notice, it disipates pretty quick so maybe its steam? it does not smell sweet like sugar it smells like exhuast, i have only put a few hundred on it since my engine swap so i dont know if it just needs time or what but i hear thats a symptom of a blown head gasket in which case i dont care i just need to know,

i remeber seeing a test on here invovling something acting like a geyser to test if the head gasket is blown? i thought it was the radiator cap... i pulled right after i turned it on and a couple minutes later the anitfreeze had steadily rose up and overflowed but not gushing up it was pretty slow and steady. i dont know if that helps or not but any input im all ears

 

Is there oil in the coolant?

I would start by doing a compression and a leakdown test.

 

I think ur engine valves or the gasket or the sealed is not tight therefore the oil from engine leaks into combustion camber. The white smoke is caused by burning of the engine oil. well just check ur engine oil to see if it leaks.

 

well maybe i was wrong might be the water condensation...

 

leakdown test? i noticed two spots underneath the car, they seem to correspond to the driver and passenger seats latitude wise in the engine bay.

 

yeah, i think ur gasket is leaking into combustion camber and burns the engine oil.

 

but the white smoke would be anitfreeze leaking, not so much the oil right?

 

Coolant will smell kind of like maple syrup. There could be many seals leaking under the hood. I doubt that your head gasket it the problem. You would notice a big reduction in performance if that was the case.

It could very well be condensation in your exhaust. How long was your car sitting before you did the swap?

If you are not sure what a compression test or leak-down test are do a google search on both. There is plenty of information on both, I am not going to be your babysitter and do the search for you.

That's not correct.

Black smoke = air/fuel mixture too rich (too much fuel)
Bluish gray smoke = burning oil
White smoke = burning coolant

Quickest way to tell the difference between water vapor and burnt coolant is the smell... Burnt coolant will smell very sweet. There's no other smell like it.

 

if I was a betting man, i would place my $$ on coolant leak

 

is a coolant leak an easy problem, and is it gonna be easy on my wallet too?

 

Since the leak is internal, you will have to take the head off and inspect the block and head for cracks. IF there are none, have the head machined flat if needed and reassemble with new

head gasket
cylander head bolts
new hoses
and

new t-stat

Is their coolant in the oil? if so, you will also need new main bearings and at this point I would be looking for a rebuilt or J/Y engine.

 

i might as well fix my crashed DX, if it is the motor the guy i got it from is getting hell

Yep, the first two things i would check. It sounds like a blown head gasket to me but check these 3 things first. Way easier than tearing the motor down and hoping you are right. But i am fairly certain it's a headgasket. Might aswell know first to be sure.

 

is a compression test something i have to take to a shop to do? or can i do it myself and how

 

does it stay there the whole time, or just on start ups? Most of the time water condensastion will go away after a few minutes of running.

It is very easy to do. Like I said before do a google search on it and you will find all there is you need to know.

 

also, if it's not getting worse, and you're not noticing a power drop, then it could just be a little water in the gas. just something to think about.

Doubtful that would cause the white smoke symptoms. It COULD be a combination of these, but highly unlikely. There has to be a coolant leak somewhere, you just have to find it now.

Have you noticed any fluids on the ground after being parked overnight? Do you have more coolant in the overflow tank than usual, or is there a diminished amount of fluid in the coolant system?

 

coolant seems to be at an ok level, but overnight on cement i did notcie two spots, almost corresponding to the drivers and passenger seat in the cabin position wise

Hmm. That really doesn't correspond with a coolant leak as nothing coolant related runs under there. Only thing I can think of running under there would be brake/fuel lines. Do you know what kind of fluid it is? Have you tried smelling it?

I mean, white smoke generally only means one thing: burning coolant. So perhaps what you're seeing is completely unrelated and just throwing you a curve?

Do you use A/C at all? Because the condesation from the A/C drips out right around that location.

 

it doesnt work to my knowledge, someone messed up the heater controls, the fan only works on the highest setting and the heat **** doesnt work, the **** is fine i think its farther back with the cable it controls, i push the AC button and it lights up but not diff at all. Ima take it apart tommorw and see whats up, the car is running ok now, my exhuast smells awful and it sounds like a pissed off v6 but no smoke anymore

That sounds more like the A/C condensation drips, if you are using the A/C. Maybe your A/C is stuck on "ON".

So now you have no more smoke?

 

correct no smoke
