white smoke ka24de

[jdm2191]

white smoke started to appear out of my exhaust about 2 weeks ago i would stop at a light then accelerate & i would see clouds of white smoke behind me :confused:???

but does this really mean i need a head gasket? Because it doesnt do it all the time......could it be my cat? Sometimes theres alot of smoke then theres times theres a little bit of smoke or not at all........

please help with this smoke from hell!!!!!

[initial_drifter]

1. Check the oil/oil cap and see if it's milky or light brown.
If it's not the usual oil you normally see then your headgasket is toast.

2. Have a friend start your car with the radiator cap off,

If you see coolant gushing then yes the Headgasket is toast.

[Tantwoforty]

check injectors aswell

i did the first step already & oil is normal

but the second step ill do tomarrow but wouldnt my car be already over heating? Because it dont over heat at all

[jdm2191]

check injectors aswell
the injectors could cause white smoke also?

[hOngsterr]

it's probably a bad gasket.

[gotspins13]

i got my coupe liek that and the first thing i did was pull the motor and change the head gasket and 5peedswap. runs like a champ now=]

[jdm2191]

ok guys the smoke is more like white with a little bit of black/gray what is does that mean?

[bardabe]

is your gas milage shitty? you can have bad injector O Rings, mad flooding the Engine. don't ask me how I know

[RaceBredS14]

i hate how everyone always automatically assumes smoke means headgasket. I had the same exact problem. Mine was valve guide seals and when you sit at a light or at idle the oil will leak around them and when you start to accelerate it burns the oil and it comes out your exhaust. Not that bad i guess.

[93nismo]

not to thread jack, but when i get on the gas, sometimes a little white smoke comes out. i think i need the valve cover gasket judgeing but the oil residue around there. but the other day when i started it it sounded like hella backfire and a huuge poof of it poped out. thats only happened onces tho. think it could be the same thing?


ive got a kade btw

[hOngsterr]

its called running super rich
lol
i do that too
w/o the white smoke mines black lol
T_T

interesting. lol thanks for aswering my question:)

[blksylv]

ya i had this prob last week and my #1 injector was bad. basically it was running wide open and the cap on the end had came off. once i changed out tht injector everythings fine now tho. check to see what the smoke smells like also, tht should give u a good clue also. gl

was your smoke white because of it??

yeah my gas goes fast actually.........could my O rings cause that white smoke? you gotta check it out juan ASAP!!!!

was it throwing out white smoke here & there not all the time?? beacuse my car does not over heat at all!!! what should the smoke smell like??

[fran13]

yes as a matter of fact my car was doing the same thing, and it turned out to be a bad injector. u were able to see the gas coming out of my manifold. so check for that could be a sign.

ok bro ill check it out........how did you car run? could you feel it had a bad injector??

[fran13]

go for it dude. i actuallly did not feel anything. the white smoke was super bad. and like i said the gas was leaking out of the manifold and i checked the injector and sure enough it was messed up.

[jdm2191]

go for it dude. i actuallly did not feel anything. the white smoke was super bad. and like i said the gas was leaking out of the manifold and i checked the injector and sure enough it was messed up.
so your car would run cool even though you had a bad injector?? because no gas leaks from mine.....
did you have a bad O-ring also? was that why it leaked??

[fran13]

well it was lagging power and my gas would just go from half tank to 1/4 in like minutes, and yeah the o-ring was really really bad. have u taken off the injectors to check them out.?

[jdm2191]

no i havnt yet but my cars dont seem to lag though??.......but i could start to hear my injector you know that clicking noise........
& i check by putting injector cleaner into right??

[SilviaSR20DET]

my ka-t is doing the same thing.... the smoke is just frustrating to diagnose. Car runs perfect as well. Might be valve guides...have you removed your valve cover before
?

not not yet i have only had the car for 2 months but me & a friend are gona check it out...........but the valve guides can cause that white smoke also??

yea i kno right i was gonna tell u that too

who agree wit me about AM-PM gas thats the

worst gas you can put in your car its half water/gas

really bad for cars my moms truck use to trip a lot with that gas than

when i started puttin shells or chevron the car runs fine and it didnt

lose power. adrain member that day we went to the meet on wednesday

night well your car was smokin like crazy its becuz you barly put in that

shitty gas from am pm trust me dude......

remember NO MORE am-pm:cops:

[wangan_cruiser]

smells fuel with that so called "white smoke" ?



check your o-rings seals from the injector


my friend just fixed his last night

[jdm2191]

damn the smell i dont really know what it smells like....ill try & check it somehow

[boobs13]

No more am_pm

[jdm2191]

some guy said that my smoke is from my car burning the oil & something about my rings.........can someone please lmk what he means by that??

[JKL1031]

bump, for same problem. maybe running rich, friend says he smells gas, drove the car almost two hours to school, no overheating. Have extra old injectors, but old engine maybe sold when i get back :-( running 87octane gas and fuel cleaner too.

[jdm2191]

damn bumping old threads turns out bad valve seals Motor ran til the day i swapped it out :)

[JKL1031]

damn...Could it be too much gas tho? I did mention there is the gasy smell.

[JKL1031]

Im willing to accept its the valve seals if so, when i have the AC on, the idle rises and burns the oil off as it comes in rather than piling it up then burning it. So,,I'll raise my idle to 1100. -Kanye shrug

[JKL1031]

so its valve seals if it idles for abit then smokes when u give it gas. Piston rings would cause smoke all the time? I need to know which to fix.

[theboy]

white smoke is coolant, blue smoke is oil, and black smoke is running rich. You have a head gasket gone bad or possibly the intake gasket from the head to the mani. Pressure test the cooling system to see if your gaskets are shot.

[waxball88]

Not always does white smoke mean headgasket, thats an old saying thats not always true. My 550cc injector had a bad lower seal and was pissing fuel into the engine, leading to a lot of white smoke, replaced the seals and it went away.
Check your injector o-rings start with the easy first.

[JKL1031]

think im loosing oil..I thought about unplugging injectors one by one, but i believe im burning oil.

[JKL1031]

no way to tell which one?

[jdm2191]

U have a different problem then me mine was valve seals I did a compression check& everything came back ok

& my smoke was more bluish then white

[JKL1031]

I read while idling oil is seeping thru the valve seals. when u rev the engine, u burn it off.
Tahts wha tim getting, i have to idle at the correct low RPM, which isnt all the time with my because race car KADE engine, then give it gas to start moving from idle, and i will see smoke. I added oil and drove today with A/C on, raising my idle, and problem minimized/did not exist. Im guessing at high idle, im burning it off as it comes in rather than all at once. 700 vs. 1100 RPM

[AZRB20]

I'm having the same problem, I only get the blueish smoke at take off, and now I'm getting a small miss at idle.. I hope it's not my HG. I'm gonna check the plugs and valve cover gasket tomorrow.

[JKL1031]

yea im getting a miss and pop at idle too, but only when the idle is too high. Ive driven the car 2 hours from home to school, w/o it over heating. not loosing coolant. I need to check my plugs as well, but have no tools here. A leaky valve cover gasket around the plugs would be nice. We did replace it before we dropped the engine in. Definitely have to hit that up.

[JKL1031]

Checked my plugs. Little traces of oil around plug two engine is bone cold. Stray silicone present inside of that hole around the valve cover and head as well as if it was a problem area for leaks from prev. Owner hoping to find more oil after.a.drive.

[Walperstyle]

did you do a compression check?

[JKL1031]

nope. Scared to. lol. But I dont think that will tell me if its the rings or valves.

[mando240]

Do a compression test.
You could have bad piston rings. White smoke generaly means your burning oil, if it had to do with fuel it would be black. Check ur oil level and see if its burning oil faster than it normally would. Touch the inside of ur exhaust tip and see if it has oil in it. Oil could have also gone into ur cat, oil + heat = alot of white smoke. It can be alot of different things. Open ur oil cap and see if u have blowby. If u have white smoke coming out of ur oil cap thats a good sign of an unhealthy motor. you can also remove ur sparkplugs and try to see with a flash light if u have oil on top of one of ur pistons. Could also be valve seals.. list goes on and on.

But just doing a compression test would be alot faster to determine whats wrong with the motor.

just read this. The problem u have is not ur headgasket. U have the same exact symptons my rb25 did when my piston rings went bad.. I had horrible compression. Simple fix buy some weiseco piston rings or any of ur choise, a new headgasket, arp headbolts, acl race bearings and just rebuild it.. I would also have the head sent to get cleaned measured and have ur valve seals tested just to make sure u have a fully rebuilt motor after u fix ur bottom end.

so its valve seals if it idles for abit then smokes when u give it gas. Piston rings would cause smoke all the time? I need to know which to fix.

Not really, right now i have another s14 that was my daily with a missfire, i have horrible compression and i gotta put like 3 quarts of oil before the month is over and it doesnt smoke unless i punch it. Driving normal it doesnt smoke yet but eventually it will start smoking on idle.

Stop giving wrong information.

White smoke is coolant.
Blue smoke is oil.
Black smoke is excessive fuel.

If your shit is blowing out blue smoke its rings, valve seals, or valve guides. A valve cover gasket will not cause any smoke in the exhaust. Unless its dripping onto the exhaust in the engine bay. Then your car is going to smoke from the front. Check compression, i bet it will read low.

If the piece of crap you bought is blowing white smoke, then its your head gasket, head, or block thats screwed up. Pressurise the cooling system and listen for a leak. If your too lazy to do that, check the oil. I bet its milky.

And last but not least. If that 20 year old jap scrap pos your still driving around in is blowing black smoke. Then its a safe bet youve got a leaky/stuck injector, too rich of a tune, or youve fucked up the ecu and now its stuck in limp mode. Check for codes that the ecu is storing. It will slap you in the face and tell you exactly whats wrong.


This is simple stuff people, so dont tell me your injector o-ring caused white smoke. Prove me wrong with a video and recipt from a dealership that fixed the problem. As for oil in the catalytic converter. Its still going to blow blue smoke(oil burns blue). But its also going to glow cherry red (depending on how long its been driven for).

how am i giving off the wrong information... read the post we have ruled out headgasket problems already.. Yes i forgot to put blueish/white smoke u know what i ment. In the eyes of a non mechanic they would not tell the difference between the oil/headgasket smokes.. If your going to help someone do it without an attitude and that cockyness u have..

[JKL1031]

yea who is that guy? Oil is wht/blue, but mistaken as mostly white.

[mando240]

idk but do a compression test, fastest n its free if you have the tools

[mando240]

look do this to save you time and headaches....

do a compression test COLD!!!! IF numbers come even than your headgasket is good
then right after drop a cap of Engine oil into a cylinder and do the compression test on it. If your compression shoots up 30+ psi your rings/ring-lands are gone. See when you put oil into a cylinder that has bad rings/ or ring-lands that oil tends to seal it for a good portion of the test so it will shoot ur PSI up....

Now if it does not go up or only 5-10 psi then your problem is simple. pull the head out rebuild with new valve seals and go on your happy ways.

[Alexlua]

Did you ever figure it out?

Nope, hadnt done anything yet. I'm out of my hometown, dont know many places or have many tools.

Pretty sure thats what you told me. But your trying to help hopeless people that dont know shit about their own car. Hence the reason i came accross cocky. Welcome to zilvia, now give up on helping out cause its a waist of time.

[iveexcaped3]

Do what mando said. Do a compression test if they read low then add a cap of oil to the cylinders. If it raises then yes it'll be your rings, If it doesn't change do a cylinder leak down test and that will tell you if its intake, exhaust, or head gasket. I do agree with "the boy" though yeah people mistake these colors but if you can't tell or know between the two should we really be telling the op to do compression test and other stuff that can damage the engine even more?

You are as ignorant as you sound..... you sound like a 20 year old kid. Let me tell you something EVERYONE THAT LIKES CARS HAS TO LEARN you are not born with a gift knowing how to do Mechanics or Diag a vehicle. So keep your ignorant as comments to ur self.

EVERYONE LEARNS SOMEHOW SOMEWHERE EVENTUALLY!!!

[JKL1031]

theboy u did come off pretty hard..When u burn light oil, the smoke is actually white until light hits it, then you can see the hint of blue. Also I am not hopeless, and I know more than shit about my car.

just ignore him and just pm me if you need any help. Ill help you until you have figured out whats wrong with your car.

[iveexcaped3]

just ignore him and keep the thread going this could be good info for noobs and people just google searching.

[JKL1031]

thanks yall.

[c-los13]

my sr was throwing white at idle too, the injectors were clogged up! clean em out!!! its the easiest fix! at least try it =) gl man

[iveexcaped3]

any new info jkl1031???

[JKL1031]

No, It wont be too soon before I get any testing done.

[mando240]

just ignore him and keep the thread going this could be good info for noobs and people just Google searching.

that's why i don't want to stop helping him, im tired of using the search button and only finding posts with people that are having similar problems that i have been searching and then no one response to it..

[iveexcaped3]

Exactly, then you start a thread and they cry about people not searching and clogging up the forum. It's a catch 22 it'll never end. Not trying to talk s*** but if the op ask for help and people give them test to do the op needs to jump on it. Not saying that they don't have a life to live but personally I don't think they should be asking questions if their not dedicated or ready to finding a solution.
