my car ran without a problem before i tore the ecu and wiring apart to make way for a new standalone. so the car sat for 3 months almost.

now after wiring up the car. it starts up fine , idles steady at 1000rpm with all emission and BAC blocked off.

but it is spewing out white smoke , gobs of it( after warming up , water temp is 80degree C steady) . could it be the coolant seal? but my water/coolant level does not decrease. I have't driven it yet cause i dont want to make things worse

Any idea whats happening? i also notice some spots of oil ( like 2mm-4mm) near the turbine side of the turbo ( my downpipe is leaking exhaust). i run a dry center catridge T04B with 0 miles on it.

Pls help

thanks all

p/s: i have a video of it 15meg if anyone could be kind enough to help me host it cause i think that will explain better.

its like -1 degree C here right now. So i am unsure cause the air i breathe out is like white smoke. Hope i can get clarification for this from the experts.

I PM'd you RE: the video..

thank you so much for helping

Mine did the same thing, I let it sit for 6 months, and when I finally start her up it gobs out lots of white smoke. I put my hand in the white smoke and its moist, so its defenitly water. I checked the coolant for air bubbles and nothing, not a single one. I too am not losing coolant.

Maybe its just extreme condensation in te exhaust system? thats all I can think of at the moment..

BlackPlague: How is it right now? is it still smoking? i hope you are right cause the engine only have like 15kmiles after rebuilt and i have no more money to go for a new rebuilt

anyone else have any ideas?

SureShot: can i mail the video to u tonight? thanks a lot

I had my car running for about 25 minutes straight diagnosing it, there were vac leaks, timing problems, thermostat not opening, bad rad cap, leaking exhaust manifold, all kinds of **** wrong. I have corrected alot of that now, and am ready to start it up again in a couple days. I just have to finish building my vacuum spider and that will be about all I need to get done before I start it.

I'll get back to you after all the kinks are worked out and I let it run for a good hour or so.

I just checked out your vid and mine does the same thing, except mine was running in about -35 degree celcius weather!. I have also left it for about 6 months and this was not apparent before. I too had also just had a rebuild done within about 5000kms, so we share the same problem for sure.

Honestly after all the **** I get done, and I drive it around for a day and its still not gone, I can only assume that the seals went becuase of one thing.

Water in the block during winter. I had some amounts of water in there, so its possible that the water expanded (what was left) in the block, not cracking it, but ******* up the seals. Thats all I can think of. we'll see....

FC_mania

i hope your car gets well black plague. so a few drops of water into the combustion chamber means Kaboom for the RE?

=( sigh... anyone have any idea what is happening?

i have no vac leaks just a downpipe leak with some oil squirting out from it... i wonder if that is normal......

if anyone needs more info of what is goin on i can provide them to help myself out.... anyone with tips and idea to keep it running for another year is appreciated too....

does your turbo have a built in restrictor in it, or are your lines properly sized? for the oil feed of the turbo, that might be oil boiling in the exhaust pipe. Does the smoke smell like fuel, or like oil, or like cooland what does it smell like.

RXciting

Just watched the video, and, might be just the video, but the smoke looks kinda blue.
Maybe Jreynish has a point and your dumping too much oil into the turbo? Or did you run the same setup b4 tearing the stock ECU out? Looks nicely put together. Hope it's not something major.

FC_mania

jreynish: Its a Garrett T04B , i have not much knowledge on turbos. i used the same oil lines from my previous turbo which is a T04R but before there is no smoke. Both runs dry center catridge. How does oil boil in the exhaust pipe? and how can i check for it? The smoke smells like how it used to smell running the old setup which there is no smoke. The smoke burns my eyes like how you are cutting onions tho. =)

RXciting: thanks i have no idea whether it is dumping too much oil to the turbo. oil level is the same , no leaks on the oil inlet/outlet. but there seems to be oil around where the turbine side meets the downpipe .

Pls help .... I would love to get it on the road =~( and hope i dont need a rebuilt as i have no $$$ anymore for it.

kenn_chan

you didn't mentin which model engine you have installed, does your car have the electric OMP, or the Mechanical? (no I have not tried to download the video) If you hooked up a stand alone to the electric style OMP did you rest the OMP so that its at 50%, or is it jammed wide open my a misconnected wire? your OMP can dump enough oil to make it smoke at a idle ~1500 if its wide open.....Just a thought.

and no I can't spell worth a **** on a good day let alone after 10 hours at work!

well i blocked off the OMP running premix 1 oz to 1 gallon ratio using a Microtech LT8s.......its an S5 btw.

=) hope that helps

FC_mania

damn the video is down... stupid angel fire ..... anyone knows of a better free video hosting website?

T2monster

Mine smokes almost constantly with as much as 2.6oz per 5gal, or roughly .5oz/gal.



1oz to 1 gal? doesn't that sound pretty excessive to you guys? Anybody else pick up on that?

That would mean 1 quart every 500 miles if running through the omp. WAY too much if it was my car.

FC_mania

Hi thanks for your contribution. So you think its the pre-mix? some other forums tell me that pre-mix shouldnt spew white smoke.....it looks like white smoke to me heheh.... waiting to get those video online

btw since its winter i also switched to 10W30 instead of the usual 20W50 it used to have before winter came.

T2monster

bleh, i'm still asleep. looking at the consmption rate from the omp in the manual, I'd guess it to be a/b 100 to1. interesting. Now I have some detective work to do on my car.

Changing the oil to 10w30 shouldn't cause anything like that. It honestly sounds like condensation to me.

FC_mania

well i idled it twice to warm it up .... both times idled for 5 mins......both times it spew out gobs of smoke... the first time i notice i didnt tighten my LIM screw properly and i have leaking coolant so i stop the car immediately .... changed every gasket and made sure all is tight right now.......

so now i have no leaks except some kind of a weird oil coming out from the turbine/downpipe exhaust leak..... but still white smoke....

anyone here think its safe to drive it out to see what happens?

ok do me a favor, take off your downpipe, take a flash light and look into the turbo outlet (exhaust) and if there is oil sitting in there you might either have a blown turbo Seal (because you have no restrictor in your turbo) or that your engine is doing that but I really doubt it is your engine I believe it is turbo related, did you buy the turbo privately? or did you buy it from a shop if you bought it from a shop ask them if you should need to add a restrictor inline, if not then I would contact garrett. I am almost 100% positive that it is your turbo leaking oil through the turbine side.
Another very real possibility since you say you are running Microtech is that it is SUPER RICH! My car before I started tunning AFR's at iddle ran smoke clouds like your and it make me gasp for air and stung my eyes.... maybe you are just running super super rich... do a little bit of tunning with your WB02.

FC_mania

jreynish: alright let me try tuning it for idle then lol =) never thought that i could be running rich with white smoke instead of black. I bought the turbo off ebay from a company . What is the restrictor? and how does it look like?

oops and i forgot i put 680cc primaries instead of the stock 550s..... let me try idling it and tuning it leaner and hope i get good results =)

what other possibilities can there be other than

-blown coolant seals
-running damn rich at idle
-no restrictor on turbo? (got a pic?) where should it be at?
-moisture in the engine because it sat for almost 4 months?

FC_mania

Jreynish: I think i got what u mean..... u put this part to the oil inlet line? i didnt have this part on my turbo right now.... So I should actually buy this part and screw it in my oil inlet line?(just wondering how come my previoius T04R didn't use this but it didnt smoke?)

I am using a T04B do u think this is the right part for me?

Well I would like to tell you that the T04R has a larger center section and Might have had a restrictor built in. But I can't for sure. But definately call the manufacturer of the turbo and ask them as to their recomendations for turbo supply and return lines. As for tunning yes it can run rich and smoke a white smoke with a blue/purple haze. But since the Microtech Base fuel map is made for 550's I am willing to bet that you are just running rich. But I would check that your turbine housing is spuing out oil.
Let us know how it goes, and I would still suggest you talk to the turbo's manufacturer and see what their prequesite is for oil supply/return.

FC_mania

the turbo has 0 miles bought new from garrett honeywell...

its a full T04B setup.....

the thing is i took out the downpipe today and snap this pic and there is no oil visible... but note on the second picture droplets of oil on the wastegate line and wastegate etc....

=( whats happening







here is the oil when i put some aluminum foil over the turbine side/downpipe to cut down the exhaust leak and found some oil.... could it be premix? cause my fuel tank is really dried then i poured in 11oz of 2 stroke oil then only i added 10 gallons of gas.
