okay...i have a b18b in my eg hatch with a turbo kit. about a month ago, i boost , 7psi about three times in a row, when i came to a stop and was letting the turbo cool down, white smoke started coming out of the exhuast, it was kinda a lot.

i then drove home, about a 10 second drive from where i was at, and then i checked the muffler, and there was no smoke at all. i reved the motor, and no smoke. it just stop smoking completely.

i checked the oil, no coolant, i checked for bubbles in the radiator, no bubbles, i took off the valve cover, no milky stuff. don't know why it smoked. i did a compression test and they were all 180 except for one, it was 175, so i figured everything was good.

i've gone about a month with boosting on the weekends, running cars, and no white smoke, but

now..today, i raced two cars, after i ran one car on a roll, i pulled over, there was some white smoke coming out for about 10 seconds and then it stopped. it wasn't that much. later on during the night, i raced another car from a stop, did a turnaround, then stopped to talk to the guy. a few seconds later, white smoke starts coming from the muffler again...this time it was kinda a lot. it came out for a few seconds, then stopped again.

i was told that when i get on it, sometimes there's a little white puff of smoke coming out of the muffler.

here's what i do know, on the bottom side of the intake mani, there are three bolts missing. i didn't know that, but i figured when my supercharger was taken off, my cousin forgot to put those bolts on or something. they had to have been like this before i was turbo'ed cause i didn't get turbo'ed until a month later and i never had white smoke coming out of the muffler.

do you think that since i'm boosting now, 7-8psi, that maybe coolant can be leaking in cause those bolts or missing? my rings maybe going bad, or i may have a small crack in the head gasket?

it doesn't happen all the time when i boost. like i said, i went a month with boosting and it didn't happen until today, it didn't again. i'm not overheating or anything either.

what you guys think?

anyone???

yup.

those bolts are only torqued to 12ftlbs if i recall.

so missing 3 out of 8 of them is bad. its likely coolant is getting into one of the intake ports. i would remove the intake manifold and replace the intake manifold gasket and install all the bolts. i know some are a bitch just take your time and do it right. since its paper and likely soaked, the gasket could cause problems in the future.

sometimes its hard for me to tell if its smoke from oil or water. To my eyes, oily somke is grey not blue and water is white. The way i tell is that the water vaporizes in the air where the oily smoke tends to linger longer.

Aside from doing what falcongsr said answer these qeustions:

1) how old is the turbo?
2) where on the oil pan is it tapped on the top, middle or bottom?
3) are you running a -10 hose or larger oil return line?
4) is that oil line crimped?

check your return line to make sure the oil is flowing back to the pan properly and without obstruction. oil burning (not combusting) would be a light grayish color, a little darker then coolant smoke.
Also, if it happens again, take a smell of the exhaust. If it smells strong/sharp, like it burns your eyes strong, then chances are its oil. If it smells sorta sweet, then its coolant.

good stuff!

B_1_8_hatch

the smoke is real white and just goes away when it gets in the air.

i thought oil was blue smoke.

B_1_8_hatch

i checked the spark plugs and they had oil on them. spark plug from cyl 2 had quite a bit of oil on it. the others just had some oil on it. so...bad rings or what?

B_1_8_hatch

did a compression test:

165
165
165
170

what do you guys think? do you think the spark plug tube gasket deals may be bad and therefor caused oil to get into where the spark plugs are?

do you think the oil return line could be clogged or something?

i checked the pcv valve and that seems to be fine. when i put my finger on it, its sucking in air.

what could cause oil to get to where the spark plugs are?

its not throwing any smoke out or anything when i turn it on or rev it up.

what do you guys think?

there's no smoke coming out of the oil dipstick deal either.

Hows your turbo? It could be the oil seal on your turbo is starting to go. You don't see any smoke just revving it or when its not under alot of load cause the turbos not working very hard. Just a thought.

B_1_8_hatch

turbo seems to be very good.

if the turbo was going bad, how would that get oil on the plugs?

legendboy

exact same problem

https://honda-tech.com/zerothread?id=589797

I've narrowed it down to the turbo, I'll hopefuly be trying out a different one this weekend.

B_1_8_hatch

yours seems to be smoking all the time. mine has only done it twice, then stopped.

looking for things to check for.

checked the pcv valve...its good.
checked the dipstick hole for smoke, there's none
check the breather filter, there's no oil in it
did a compression test...numbers look good
checked the oil feed line, thats good with no kinks
there's no coolant in the oil
there's no milky stuff on the oil cap
there's no bubbles in the coolant
there's no smoke at start up, when i rev, or when i drive.


one thing though, the oil feed line goes to the back of the block right? what is that sensor deal on the block that the line goes to? you know what i'm talking about? there's wire that connects to it, i noticed my wire wasn't on. i put it back on, but don't really know what its for.

i'm going to change my oil and change the return line and then change my plugs.
i'm also going to check the spark plug gasket deals to make sure they are on right.

i'm thinking somehow oil got into where the spark plugs go...don't know why yet though. i hope its not my rings or the turbo!!

Milky stuff in your oil usually means there's coolant in it. Blown headgasket, maybe? A blown headgasket could still yield "good" compression test numbers, yet leak under boost. Just something to think about.

B_1_8_hatch

meant to put there's NO milky stuff under the oil cap...sorry.

SJP0tato

I agree with FalconGSR. I'm pretty sure coolant runs through part of the intake manifold closest to cylinder #4. If you're missing bolts, it might be coming slightly loose and allowing coolant to be sucked into the #4 runner which would give the exact same white smoke symptoms as a blown headgasket...without the bubbles in the coolant/milkshake oil/ect. Try replacing the intake manifold gasket, and use all the bolts this time and test it out.

Good luck,

That sound like you oil pressure sensor.

AlphaKennyWun

Are you watching the boost gauge when racing? Are you sure youre not spiking? You could be getting extreme temperatures in your cylinders and killing your pistons and rings slowly if your spiking.

B_1_8_hatch

explain spiking to me?

yes i watch my boost guage. sometimes it reads 8psi and sometimes it reads 9psi.

any ideas? i thought maybe it was just the boost guage. its a jacksonracing boost guage. i used to be supercharged so thats why i'm using that one.

Poop111444

SPiking - say u have a 6psi spring in your wastegate, and your boosting and then BOOM for a moment it spikes up to 15psi! I've done that before hehe.


Also the oil on your plugs..... WAS IT ON THE THREADS OR THE TOP OF THE PLUG?

B_1_8_hatch

my boost usually stays at 8-9 psi and my deal is set to run 8psi not 7psi.

the oil was on the threads when i took out the spark plug.

AlphaKennyWun

Its when you think you boost is steady at lets say 7 psi but actually climbs higher. I had a friend tell me that he looked at my boost gauge and it went to 20 psi during a race. I fixed it but needless to say the damage to the pistons was already done.

B_1_8_hatch

nah...my boost doesn't go that high. i always look at it when i get on it to make sure i'm hitting the right amount of boost.

hondaeg8

maybe its the return line backing up oil.

i would replace the spark plug gasket deals under the valve cover. they could have
gone bad and therefore letting oil get into the chamber.

if it doesn't smoke all the time and your compression numbers are good, don't really think its your rings

B_1_8_hatch

anyone else got some opinions on this?
