i got a 91 DA with a b18a1 th car has moisture coming out the exhaust i need some help on figuring it out i did compression check all cylinders were 165 or higher other than than all i have on the car is a aem cai and an hks highpower exhaust

 

condensation...nothing to worry about

 

bt its smoking more than usual i left it running for liek 2 housr and it never went away

 

bump

 

If the compression test was ok, it's probably not burning oil...is it thick black smoke or light greyish smoke

 

really light it diappears quick but its smoking like moisture or something its not oil burning

 

Some people try seafoaming their cars...It's made to clean carbon, and varinsh build up off the valves, pistons, rings, etc. Will also help clean sticky lifters or valves...you could try that...maybe some fuel cleaner

 

dont use seafoam, especially if it is a old motor. sea foam just unclogs your rings of oil deposits and will smoke more eventually. could be possible head gasket leak that is very small.

 

if its a small head leak compression should leak too i know about seafoam and yes u are right about the old motors this is just a weird situation what else could cause it?

 

Ok well...Whitish smoke is usually caused by water or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result...you said it was light smoke right? like a whitish color?

 

also, i found out on my DA when my headgasket started too go, i seen a mixture of oil IN my radiator fluid about week before my actual oil got milky. check your oil cap and if its a milky white color, you'll know. then check your radiator to see if any oil is mixed in the fulid.

 

i already checked it and there is none at all thats why im confused i check all my oil and oil cap there is no mixture i would have known if there was a ,mixture but there isnt so im still wondering what else could it be

 

i also was wondering why i was smokin cause i havnt turned on my integra for a while.. and i did see sum oily substance n my radiator when i toped it odd wit water and al lil smoke comin from the trans area..u think it would jus be the head gaskets?

 

i say head gasket cuz u have it in your oil and radiator

 

i read ur post and i also get steam/light smoke comin out the engine i thought it mite have been water in the block from a bad gasket..but ima go buy a whole gasket set in a min.. i checked the dipstick but i wasnt able to tell if it had water in it..n i wanna get that mystery smoke prob solved..

 

some times even tho you let it idle for two hours the exhaust still may not be warmed up enough. take a 15 min ride and see if it still smokes. had the same problem just needed heating up. more gases more heat no condensation.

 

ok i might do a leak down test also
