recent swap we did on buddy's hf crx, swapped in a d16a6 with high comp pistons, it was running great and VERY strong except for idle being jumpy for the past week, we put about 600miles on it already, and changed oil ect...., this mornin he drove it to class, and said that there is water coming out of his exhaust tip after driving the car.... could it be that the block has cracked? or what has happened.... the idle is still jumpy as it was previously....need help asap. thanks!!

bump! need help please!

 

sounds to me like it is just condensation, which is normal - unless it is a lot of water

 

is there anyway that it could be that the block is the culprit??

 

doubt it - the only way to get water into the exhaust is with cracked head or blown headgasket - cracked head or blown headgasket would also have water in the oil

 

oh, ok, thanks very very much! (sigh of releif)

 

there would also be a big cloud of white smoke that willl fill the streets and not go away for a wile.

 

^ would that be from the water in the oil or?? thanks

 

white smoke out the exhaust is actually steam from water getting into the hot combustion chambers

 

If the oil isn't milky you're probably fine.

 

oh, i see... what way can i check if oil is milky without draining it?? cause it has gone through literally only 30 miles since we changed it... and dont wanna go out and buy synthetic all over again... thanks!

 

take the valve cover off - if it has water in the oil, it will like like someone poured milk into it

 

Checking the dipstick will work too normally.

ya, my point is, if water is dripping out of your exhaust , its most likely not coolant because it would smoke not drip out.

 

thing is, no coolant, its cali... its just water in the rad.... lol. the swap was just done, so we are using water still cause all rad hoses keep slowly bursting...

 

it would still smoke and not just drip out. when water hits somethign hot(exhaust) it creates steam.

 

hmm... interesting... hopefully its just the headgasket...

 

Is it smoking or just dripping water? Water is a natural byproduct of combustion that why your exhaust system will rust out before anything else.

 

ah, i see.... so everything should be normal then?? right on... thanks! saved buddy from buyin new head gasket...

 

you said it was idle hopping, ur iacv will cuz this if ur low on coolant.

 

hmmm. we top off the water/coolant before the car ever gets hot... so dont know about that one...

another thing though is that the oil light comes on soon as the idle goes below 1k, it goes on, and soon as you hit 1k idle, the light turns off.... there have been a few times where the idle just dropped and the car shut off...

 

Like everyone says if you where burning water/coolant it would be smoking, not driping out. If you want to know for sure you could have a leak down test done on each cylinder. It is liks a compression test except it fills your cylinder with air and measures how much air is escaping, and where it is escaping to. As far as the oil light you could have many diffrent problems. It couls be a dent in the oil pan, a cloged oil pickup, bad oil pump, un-clearenced bearings during the rebuild, faulty pressure switch, etc.

buddy just checked the oil, the oil is a milky and has a bunch of white stuff on edges he says.... any input??? would just swapping the headgasket help anything? or is it most likely block/head?? thanks.

 

Pull the head and have it pressure checked along with checking the surfaces to make sure it's not warped. Then put a new head gasket on.

I'd double check the dipstick along with the oil cap before going through that trouble though just to make sure it is milky. It should look almost a carmel color.

The block is almost never the culprit in situations like this. Only thing that could be wrong is the surface not being straight.

 

there is none of the white stuff on the dipstick
