i have a 1990 honda civic d16a6, i recently changed the head gasket on it, but i didn't mill the head. the car still smokes and blows water out the tail pipe, also it does not idle it jumps around like 1k to 2k cannot adjust it. does this mean i need a new head or block? or do i just need to mill the head and a new head gasket?

 

well technically... water is suppost to come out of the exhaust. its called condensation. what color is it smoking? white or blue? does it "jump" as in up down? braahbraahbraahbraah? or just 1k for most the time then randomly idle at 2k?

 

well i understand the condisation part but its not supposed to last the whole time my car is on is it? and the idle is either at 1 or 2 no jumping like if the idle postion sensor was bad. and its greyish smoke like steam

 

about the idle problem have u cleaned the sensor on the back of the intake manifold?

 

no i havent cleaned it. i want to get the heating and cooling system and no smoke coming from the pipe first. but i will keep that in mind when i get done with that stuff first. what does it look like? and how do i clean it?

Idle position sensor? There is a chance that some of that smoke is from what is in the exhaust from the head gasket change, this is common after a HG change.

 

really? even the water coming for the pipe is normal? i changed the gasket and i've ran it maybe 4 times and the water still comes out pipe and i take the radiator cap off and i get air bubbles witch means head gasket right? and my car wont stay at a steady idle its either at 1k or 1.5k it wont idle at 700 like its supposed to. im going to take the head off again and see what happens. ill post a picture with the head off and maybe that will give a closer look at it

 

ok i took the head gasket off again and replaced it and i went to the shop and had the head milled down and my vaulve's cleaned but im still getting a smoke comming from the pipe and drops of water. the ecu is giving me a code 1 and 7 i know the 1 is o2 sensor. but code 7? i need help with my car and why it smokes so much

 

holy crap dude.... like i said. WATER WILL COME OUT!! look at the cars around you... water dripping out of the pipe. what color smoke now? you COULD have a leaky intake mani gasket, sucking water into the mani, then burning it thus causing smoke. and unless water is pouring out at a gallon a min, then dont worry about it

 

im just no used to a car that smokes is all. my accord didnt smoke and the compression was way to low from bad rings. but thanks for the info, if my car doesnt pass emissions than ill worry

 

well dude all of ur posts here are about water coming out of tail pipes.. i dont think his car runs on hydrogen.. but DID u time it right when u put it back together? check ur compression and post it on here if u want!??.. like the civic dude up top wrote, clean the idle position sensor

 

compression is high and stays high, timing is right on the dot and i cleanedd the position sensor. ichecked all these things, i also checked every vacume to see if that was it and none were broke, i did a full tune up after i changed the head gasket oil,oilfilter,plugs,plug wires,cap,rotor,even a new timing belt. the engine doesnt idle right either i cant get it to go lower than 1k
