hey so got the integra going with no codes no overheating
total time ive had the engine running 5 mins
machined and dipd 96 pr3-4 head replaced valves

no cel sounds the part (no lma tick) but im getn a black white smoke after it gets abit of revs

i also notice a puddle under the exhaust.
this is the first time ive had the engine running since its been put together

could a have mixed up some of the vacume lines?

 

Did the engine get a chance to warm up in that 5 minutes?
Could have a bad head gasket, and could be running rich.

 

not realy it didnt get to hot.. the radiator fan isnt working but goin to deal with that tomorow
it jus been put together, not from me but u would ''think'' he would have got a new headgasket if he go threw the trouble of sending head to shop..
i also didnt see ne bubles in the coolent reserver and theres no oil in the coolent or vice versa

 

Just a question, did you lap the new valves in?

 

i brought the engine as is. the guy did a wire tuck on my crx and did a good job, didnt half *** anythink.
is there a way to tell

 

A way to tell if the valves were lapped? No, I mean you could take the head off and have it pressure tested to make sure they are sealing correctly, if they weren't lapped or machined it will not seal correctly.

 

were ur valves adjusted after all this work? any odd sounds at all?

 

i couldnt tell you, the work on the motor was done before i owned it. no theres nothing that i heard. it sounded real healthy, i couldent hear the lost motion's at all.
although theres like a whiring humming noise comeing out of the air filter when key is ON
other then that no.

my tourqe wrench turns up today i will open her up, what should i be looking for?
btw i have no specialist tools atm but that shud change by xmas
is there any visual to be look for?
thanks guy's my 28th january deadline is comeing close haha

 

a better discription of the exhaust color would help more, you said black white smoke. Is it black the turns white. Or a gray color, as in black and white combined? Or is it dark white with a blue hue?

 

it's abit hard to explain (or i dont want to admit) its smoking more whit then anything, its abit hard to see if it's gray or black but there is a mixed colour in there.
and i just let it run for 5 mins, no smoke. gave it a rev then it started to smoke.

just done the clutch release bearing bowt to put gearbox on then take it round the block... but is that a good idea? i dont want to damage it but ive read that it kan take awhile for the valves to sit. i havnt lost any coolent!!
but i have a mass amount of water on the ground beneath the exhauast and at the end of the pipe

condensation mayb? car hasnt been going since feb
cheers

 

To me it sounds like you have white smoke with a darkness to it like a blue hue. That's oil burning. And you said it doesn't do it after 5 minutes of running? After heating up the metal parts expand and that is probably why it no longer burns oil after warming up. But if it's straight white it is coolant burning, either a head gasket, or intake manifold gasket where the coolant flows through the intake manifold to the head.

 

I have recently had the pleasure of going through what you are.

If the valves were not adjusted after the head was put on it is not gaped right

Also the block I just bought more than likely has bad piston rings.

I take car in tuesday to find out for sure will let you know.

 

nah i can have the motor runing for a gud 5 mins give it a rev then it wants to smoke.ive seen a coolent leak before and it had smoke as soon as the engine started.... im goi to drive it around the block unless that wud damage something??

cheers let me know

 

let it run a bit. if you have coolant in your system you will smell a sweet hint to the smoke. and if its oil burning check your oil see if it smells like gas. it could be your rings.

 

im only using water for coolent atm sorry forgot to say. and also to note i havnt lost any coolent aswell.

im going to go out to shed and connect gearbox(jus been using barell housing and starter to get going)

will come back after done it and see if anybody opposes to not take it for a drive round the block.

i dont want to do damage but im thinking its condensation i hope.
coz as mentioned up there^^ i have a big puddle under my exhaust and two large amounts in my stock twin pipe exhaust..
an i know thats the cat's job to turn emmisions in to water kinda...u get wat i mean

 

Yeah dive it

 

could just be valve seals too, if they werent replaced at the same time and depending how miles were on the head when the valves were replaced.

 

well...took it for a drive round the block, no smoke
so while it was idleing gave it a rev past 5k then it bellows out thick white and blue smoke.
first thought piston rings?

what else could be the culprit?

 

Blue smoke sounds like rings...white smoke could be headgasket or coolant getting mixed in ur intake.

 

Or like you said, valve seals. The idiot that sold you the head may not have replaced them.

 

Keep running it if the oil turns black fast its your rings

 

i bought this engine with out seeing it goin, will NOT be doin that again...
i would rip it apart and start again but i have another motor disasembeld waitn for my crx (next project)

im using 10w 30 synthetic oil.
also the idiot didnt have a valve cover gasket.. changed that yester day
was thinking oil could have been leeking into the exhaust manifold

other then that im thinking rings =(

alllso while it wasnt somking, i went down to the muffler and listend in,
to my surprise it sounded like water flowing down it

and by the colour of the smoke we can rule out headgasket

 

thats a great idea i need to goe to town so im goin to cruise the way there.. bwt a 5 mins drive. how long will i need to keep it running till i see change?

 

you could always smell the exhaust too while the car is running, if it smells sweet, its coolant.

 

theres only water for coolent would that still give that smell off? ihavnt smelld it yet...
but its a thick white with a definite blue... even got my lil bro an he could c blue aswell
