I fired up my built engine from like 5 months ago (threw my LS into my teggy cuz of Ref) and i noticed that there was a good amount of water in the exhaust side of my turbo once i fired it up for like 10min. Slpapped it back on and there was good amount of water in my muffler and everyday i would turn it on once for 4 days in a row and i would have to fill up my resevoir with coolant(lika a cup everyday) only when it would sit for hours , NOT while its running though. There is White smoke constantly flowing out of the exhaust and water.This is what i have in the cooling system:
Mugen thermostat and fan switch
Cometic Head gasket
Koyo rad
and no CAT

Im thinking its the head gasket, but it doesnt burn it while its running or leaks any coolant im STUCK

 

what engine/bore is it?

 

A compression test would be helpful

 

My engine bore is 81.50mm
and i cant remember if i got the Cometic head gasket 81mm or 81.50mm... im pretty sure it is 81.50mm gasket.

 

oh, so stock sleeves... how much boost and power has this engine made/been put through?

 

Yea stock sleeves
Im boosting 7 psi on a Rev Hard Turbo kit.
I havnt tuned it yet, but i will.and ive only put like 1,500-2,000k miles

What could be the prblem its driving NUTS

 

Bump

 

the problem could definitely be drivin it 2000 mi untuned. it takes about 1 second to do some serious damage. i'd guess blown headgasket or cracked sleeve. you probably need to pull the head and take a look. i'd even recommend using a stock honda head gasket when you put it back together. if you put it back together (may be some damage)

 

I will pull out the head and keep it posting
Thanks guys

 

i dont think Honda sells oversize bore headgasket so should i still buy it.
Im 81.50mm!

 

No damage in the block, but the head gasket looked like chocolate milk probably from coolant mixing when removing the head.
What would be the recommendations: Honda headgasket or Cometic 81.50mm .051" thickness headgasket??

 

just a good ol stock honda one. made 600hp in a 85mm bore no prob. i'd guess the combustion chambers in the head are stock size, right? if they are, .125mm of a headgasket stickin out doesn't really matter

 

Driving a recent turbo car Untune is beyond stupid. It like dumping 2X the amount of air and same amount of fuel. 1. Install the turbocharger kit. 2. Some kind of EMS with a base map. 3. Drive it unboost to the Dyno and get it tune. 4. Drive it the way you want.

 

Yea i know i should of tuned it but other stuff came up and money was tight.
ima tune ASAP!!

 

I replaced the head gasket with a Honda one and the same thing is happening!!!!
Bump!

 

i dunno if it explains the water in the muff but my collant was just going like crazy so i just put a bottle of radiator stop leak and its held ever since.

 

try not to fill up the resevoir tank alot and see if your car will overheat....then it would be easier to eliminate your problem....

 

thats the weird thing about mine is the over flow would be completely empty but it would be completely to the top of radiator cap and wouldn't over heat, and none was leaking on garage floor

 

You're contradicting yourself here. White smoke out the exhaust means coolant is getting into the combustion chamber = blown head gasket, or possibly worse, cracked cylinder walls.

 

its weird cuz i have white smoke constantly coming out of my exhaust even when my motor is fully warmed up to operating temps but it could just be that its 20 degrees out side...not loosing coolant and car is not overheating...but its just weird..i say if its not over heating then just fill up the tank and leave it for awhile

 

All cars appear to smoke on cold mornings. This is just steam burning off and is nothing to be concerned about.

 

actually i always have steam and water coming out...but yet maybe since its always cold thats why its always like that...never noticed it till the cold weathers so im not to worried...

 

I replaced the head gasket, and everything else was fine, but still doing the same thing as from the start... i havnt played with my teggy but ill drive it around the block to check how its doing. Thanks guys

 

I drove the car for a few miles and no coolant missing and i guess the smoke and water is just condensation!!
Thanks for everything guys!!!

 

Check it after a few days. I like to check my oil and coolant levels on Saturday morning before I first drive the car.
