okay just got done rebuilding my motor again. and when we started it up smoke was coming out of the exhuast, a lot of it too. what the problem. did a compression test and all 4 cylinder came out 230. any advice. oh and there is no coolant in the motor yet too. it drives fine tho. can it be my PCV?

anyone?

 

smoke on exhaust.

too much fule/air, or other way.

did you reset the ECU? and let idel for 10-15 min after engine is warmed?

 

damm no coolant..

hey I did mine and machine shop messed up the wrist pin that destroyed 1
cylinder wall.

 

anyone else got some other ideas?

 

okay change my PCV now the smoke is gone a little bit you can only tell that it burning white smoke while driving it for a while but if it idles then it won't smoke. remember there no coolant in the motor. and my a/f gauge show that i'm running too lean and rich, but it not a wide band. running with a chipped p75.

 

Um... correct me if I'm wrong, but doesn't an engine create enough heat to destroy itself if you don't have something to take away the heat... kinda like coolant.

 

no i'm just letting it run to were it gets to normal temperature. but i dont know why it burning out white smoke if their is no coolant.

 

Hmm this sounds wierd to me.

 

So you don't even have water in it? Doubt you would do that. Whether you have coolant/water mix or just water, won't matter, that has no bearing on the white smoke issue.

You might need to let the oil rings seat themselves some more and since your just running it a few minutes at a time, not being driven, the engine doesn't have the necessary load to seat the oil rings. Did you replace your valve seals? Use a new OEM headgasket and torqued to spec?

I know your not running it without any fluid in the cooling system, right, just sounds that way by the way you worded your thread.

You are reading it correctly.

yes i'm using OEM headgasket and it's torque to spec. didn't have a chance to replace the valve seal but the head only has like 30-40k on it and it was running fine before taken it off.

 

Btw, 230 compression in all 4 are very good compression readings, possibly a bit above normal, but thats good. It also indicates that the compression rings are doing their job. Get some coolant in that motor and see what it does, and please, stop running that thing without coolant lol.

okay... i think it might be the headgasket now... the problem is with coolant in the motor the coolant will bubble up when the seal is off and when the seal is on the coolant will go out quick and it smoke a lot from the exhuast pipe when it being driven but when it's not driven and it just idle it only smoke a little bit, not as much as it would if it was driven. and from what i hear if you start the car and open the radiator cap and it bubbles up then the headgasket is blown, right?

it's just on the compression ratio. my stock gsr motor has 235 straight across (even after being turbo'd for almost a year).

 

Yes, that's the typical indicator. Did you reuse the headgasket?

Janos

 

it might just be condensation that built up in the exhaust... how long was it sitting before it was done?

also you really really gotta put some coolant in there man..... just cause your temp needle says it isnt hot doesnt mean its true when you dont have coolant... the cylinder walls are way hoter than what is indicated on the temp guage..... youll bake your new headgasket....

temp gauge is based on coolant temps..

i hope you used a new headgasket btw.....
but after running it without coolant you might need a new headgasket if you ran it for too long....

also make sure to mix coolant dont just use water alone.... coolant also preserves the headgasket and keeps it from rusting.

no i didnt reuse the headgasket i got to order another.

AND

before taking off the head i recheck the compression and it was at 200-195-195-210. can the number drop because of the headgasket being blown? or are my rings gone too? that a big drop in compression. i looked at the sleeves and they were perfectly fine to me.

 

do a leak down test

 

EH THA SAME THING HAPPENED TO ME WHEN MY TRANNY WHEN DONE. I THOT EVERYTHIN WAS FIEN THEN I STARTED UP MY CAR AND DROVE AND A **** LOAD OF SMOKE CAME OUT OF EXHAUST IT WAS BECUS MY HEAD WAS F*ED UP I DONT KNO BOUT YOU BUT ITS JUST A THOUGHT GOOD LUCK WITH YOUR CAR THO.

will the head came out of a perfectly running car, but wasnt used for like atleast 6 months now. but i doubt anything could have made the head bad.

 

Overheating can cause the block and head to warp. If this has happened, then no headgasket is gonna save it. It will have to then be machined flat again. You can take the head off and take it to a shop and have them check it for flatness if you don't have the tools. Usually the head warps first since that gets the most heat. It's hard to determine if the rings are still good without other tests and it seems you've removed the head already. U could slap it back on and retorque it and do a leakdown test. If you hear it coming out of the oil cap, its the rings, if its coming out of the radiator, its the gasket surface. if its coming out either the intake or exhaust ports, its a damaged valve or seat. The old school method of pouring a tablespoon or so of oil down the spark plug tube and rechecking compression works, but if you add too much or too little, you'll get the wrong readings.

Janos

 

will when i put oil into the spark plug hole the compression came back up to 230 on all 4 cylinder. as far as i know, if you pour oil into the spark plug hole and compression rises then that means that the rings are gone, right? and as for a leakdown test i don't have a leak down tester. so i'm out of luck. i think i might just buy new pistons rings and a head gasket set and have the head pressure tested at a shop. see if anything wrong with it before slapping everything back on. oh and before that i took off the headers and started the car and smal amount of oil was coming thru exhuast port #1. all the other one didnt have any oil coming out of it. does that mean my valve stems seal are bad? and another small amount of oil was leaking inbetween the mead and the block right underneath exhuast port #1 (the one all the way to the left, if looking at the motor in the front.)

 

yes, but 200-190 is still pretty good though, just a tiny bit of an air leak. 120 is pretty much the point where you rebuild the motor.

Up to ya though.

Janos

 

will i already brought the pistons rings i'lll just do a leakdown test tomorrow cause i'm rent it from autozone. and will c what happens from there. hopefully if something is wrong it'll just be the piston rings instead of the head or aintthing else. oh and i drove it around today and if run fine except for all those smoke but it look like the smoke are going away but not much.
