Thick white smoke....

[the1cancer]

Ok, I was replacing my air filter today and when I was done I put everything back together (so I thought). I took it for a test drive and was amazingly boosting 23 psi boost...thinking wow, this is cool. I was hearing a weird high pitched chirping sound (but I have been hearing that for over a month) I get 3 miles from home and then poof there is a HUGE white cloud billowing from my exhaust pipe and a little from under the hood. This also made my car run like crap.

I stopped the car and looked under the hood and found that there was a vacuum tube that hooks up at the outlet of the turbo that I forgot to connect (oops),...bad turbo....

I just wondering if this can damage the engine or if I just need to toss the old turbo and get a new one.

White smoke usually means coolant is getting into the combustion chambers. My guess is a blown headgasket from running 23 psi.

 

[the1cancer]

can the 4 layer metal gaskets blow from only 23 lbs boost...I dont think so, friend runs almost 30 lbs all day long

 

[crunchymilk]

What turbo are you running? It doesn't say it in your profile. If you boosted 23psi on a 14B, the turbo is probably toast. Does it smoke all the time or only under boost?

 

[the1cancer]

smokes all the time from what I saw...I havn't run it since it happened...got too much money in the engine and scared to break it any farther....BTW its a 14b

 

[RoasT BeeF]

Yes metal HG's can blow.

Try updating your profile next time you want help so people dont have to 'guess' or 'assume' what parts you are running.

 

[crunchymilk]

I don't think it's a headgasket. The 4-layer can take MUCH more than 23psi. My guess would be a blown turbo, check for shaft play. In and out shaft play means it's gone, side to side means it's on its way out.

White Billowing smoke = coolant...

Its not the turbo. you're turbo's fine. It is PROBABLY you're headgasket and the reason you blew a 4 layer head gasket is you're running rediculously high boost with REALLY hot air. The reason its rediculously high is because you have a 14B... had you had a larger turbo, the air wouldn't have been as hot. I don't know what engine management you have, but I'd bet you had a lot of pinging/knock leading up to this. You detonated, and lucky for you, instead of blowing a hole in the piston, you blew your headgasket.

#1 I didn't say that the metal gaskets couldn't blow, I said they cant blow with only 23 lbs of boost.

#2 if you look carefully at the vehicle profile where you list your engine "mods" you only list MODS you know...modifications...you dont list stock parts aka 14b.

if you dont have something constructive to say then dont say anything.

Just so you know...It was totally the turbo...I hooked up the MAF straight up to the intake manifold and turned it on to make sure that the engine was ok and oh look massive amounts of oil started pouring out of the turbo. I turned off the car and checked for shaft play and spun it...massive shaft play and grinding when spun.

Please only post from experiance not from just guess work... thanks for the help though.

BTW 23 lbs is not rediculously high, 50 lbs is.

Will have Pics soon...

 

[the1cancer]

Wow, absolutly no damage at all to internals what so ever...the nut that holds the compressor wheel to the turbine unscrewed itself and the turbine spun out of the bearing housing. Couldn't even find one shaving of metal or anything just alot of oil.


Sweet

23 psi on a 14b is rediculously high...

And its not my fault you don't know the difference between WHITE and blueish Grey smoke... white smoke = coolant, Blueish Grey = Oil.

And how the hell are you running 23 psi on a 14b without an aftermarket intercooler, any engine management, or even water/alchy/meth injection???

How? He forgot to attach the vacuum line to the j-pipe and his wastegate wasn't opening. He was probably running more then 23psi.

not true buddy, white smoke can be a blown turbo as well. It depends where the oil is getting burned.

glad it was just the turbo. People lean WAY too much for a headgasket with any sort of white smoke.

I'd recommend a 16g for a replacement, better turbo overall of course, cheap too.

 

[the1cancer]

Yeah, Just ordered the SBR big 16g with turbine inlet port.

Got any refrences on rebuilding a 14b? Looks like its not damaged at all as far as the internals go...Possible resale

 

[oldman]

23psi is high for a 14b, way out of its efficient range. With that said, you're lucky there was no engine damage, never boost past 17psi with stock fuel system without at least a logger for monitoring knock.

I stopped the car and looked under the hood and found that there was a vacuum tube that hooks up at the outlet of the turbo that I forgot to connect (oops),...bad turbo....

This is probably the reason why your turbo took a dump. Boosting 23psi with a boost leak that size means the turbo was probably spinning at a rate that is equivelent to 30psi in order to maintain that 23psi. That vacuum tube is also suppose to be connected to your mbc which is why you got all out boost to begin with.

And its not my fault you don't know the difference between WHITE and blueish Grey smoke... white smoke = coolant, Blueish Grey = Oil.

crunchymilk is right on, unburnt oil pouring out of the hot side straight to the exhaust will look whitish with a tiny faint of blue.

Yeah, I agree. I think thats what I tried to say at the beginning. I am in the process of converting ECU to use Ostrich and DSMAP to use the great feature of Map sensor and hopefully closed loop.

I ran 1.8 bar with my 14B made over 300 whp with a 35 shot.


The nut from the compressor side also came off and killed my turbo, then I went 60-1 turbonetics.

and i'm going to guess that you had some fuel system upgrades as well as some sort of air fuel management. yeah... thats what I thought.

and probably an upgraded intercooler or water injection as well?? to keep temps down maybe?

Which is exactly why you don't run that much boost on a 14b to begin with.

 

[the1cancer]

WOW, b16g turbo gives ALOT more power =D

sounds better too, now I just gotta wait for my Ostrich and laptop to come in so I can set up the ECU properly.

450's stock sidemount, no afc, water injection ect. all stock engine with 200k before rebuild

It was all in good fun, little turbos are about as cool as pocket loggers
