I put in a used d15b2 in my hatch last night. the motor has been sitting for a few years. it starts up and runs fine. Now i know that a lil condensation out of the exhaust is normal but this one is gettin a lil more then normal. If i rev it up i see lil speckales on the ground about 3 foot out.

The car has stock exhuast almost all the way back and connects to a 2-1/4" axle back. Could the differnt size pipes have anything to do with creating more condensation? Also i dont think its the headgasket because it is not smoking at all.

 

it shouldnt, is there any oil in the water?

 

well the water is mixed with some black stuff but its carbon build up i think. I havent really driven the car yet only let it idle for 5 to 10 minutes a few times

 

my old d15 did that to but I was running open cat/custom race muffler. its not normal i do know that. not sure what it is though. does it smoke at all?

 

No smoke, maybe its the cat causing it

 

sorry but I have no clue dude. wish i could help ya out. maybe it is just extra condensation from the engine setting.

 

I know a bad intake manifold gasket can cause coolent to get into the engine but it would be smoking white if that was the case, right?

 

yeah, i think thats right. it might be the ex mani gasket though

 

A clean burning motor creates the following:

Nitrogen gas (N2) - Air is 78-percent nitrogen gas, and most of this passes right through the car engine.
Carbon dioxide (CO2) - This is one product of combustion. The carbon in the fuel bonds with the oxygen in the air.
Water vapor (H2O) - This is another product of combustion. The hydrogen in the fuel bonds with the oxygen in the air. </TD></TR></TABLE>

All, in all. You're fine. That water vapor is cooling down/condensing as it exits your exhaust and turning into the liquid form you are seeing. I always blow a 3 ft mist/spray of water when revving up after sitting at idle for a while. I've even left a few carbon stains in a few driveways (water evaporates and carbon that came out of the exhaust with the water is left behind)

 

hehehe.
thts noting to worry about,
Only ur head is working in perfect condition,
