White smoke after evoIII 16G installed

[wisek1234]

I have a 2gen eclipse 98, about 105,000 miles and the t25 turbo went on it. I decided to replace it with an EVOIII 16g turbo. I replaced the valve cover gasket, valve seals, spark plug tube seals, spark plugs, plug wires. I got the 2gen install kit from extreme psi and the turbo. The install went good everything bolted up ok. We started the car up and it ran okay, then white/grey smoke came out the tail (alot of smoke). We then did a compression test and a leak down test, both tests were good. I was wondering if anyone had any ideas of what can be causing the massive amount of white smoke coming from the exhaust pipe?
Also we changed the oil, to synthetic oil, it used to run regular oil.

Your turbo/seals might be shot. You need to build up oil pressure before starting up the car. Did you properly prime your turbo before fully running the engine?

Drive it around for at least 30 minutes and see if the smoke goes away. It might be due to condensation.

Read up on Tech guides for proper turbo installation.

Typically when an old turbo blows, it can coat the inside of the downpipe with oil from seal failure. If your vacuum and compression readings are normal and the car isn't using oil, this is likely your culprit. I would drive it for a while until the heat burns everything out of the downpipe.

If the problem persists and only happens at idle or deceleration, it could be an issue with your valve stem seals. If it happens under acceleration that's usually rings. I don't think either of these is your problem, but I wanted to cover all of the bases.

Take it for a ride or better yet, drop the DP and look for oil residue on the inside. I'm assuming you primed the new turbo before running it and I hope we can rule out seal failure in the new one as well.

Let us know what you find,

The turbo isnt bad, the car and the turbo run fine when i drive it, the exhaust just smokes alot

 

[andymoraitis]

If it only does it when cold, then it's simply condensation burning off the inside of the exhaust. It looks more like a fog than smoke. If it happens at idle, like I mentioned above and doesn'y go away, I'd point to valve stem seals.

I had the valve seals replaced, and the smoke is when i start it and continues even when it warms up and when i accelerate/ push on the gas. I havent ran the car that long becuase of the smoking out the exhaust, but the turbo spools up and the car runs good.

I read on one forum that a kinked oil return line could cause this ? anyone else heard of that?

wisek1234 : did u follow the procedure to bolt the turbo in ?
first u got to oil in the turbo before u could bolt it on
the procedure is firstly u plug the oil lines , either unscrew the manifold from the head and give it a distance to let the exhaust leak or remove the turbo clamp and remove it from turbine housing, start the car up , let the oil enter the turbo and start to come out to the oil pan , then only u r ready to bolt on the turbo
if not , hmm , u just damanged em

 

[wisek1234]

I primed the turbo, and i also ran the car for over and hour and the car is still smoking white out the exhaust, any other ideas?

 

[andymoraitis]

Did you check for side to side shaft play in the turbo as recommended? Anything excessive means it's leaking past the seals. Did you also drop the downpipe and look for oil inside. What about coolant. Are you losing or using any? Finally, does the smoke only occur at idle, acceleration, deceleration, no boost, full boost? More info on what you've done and when it's happening would help.

i think its just oil/coolant burning off from the install.

Shit you really cant break the turbo any more IF you already did infact blow the new seals.

Romp on that shit on the highway for a little and see if it goes away/ burns away completely.

just keep an eye on your oil pressure and coolant temp while doing it.

I drove the car on the Hwy for about an hr or long and it doesnt smoke anymore when im driving, but when the car is ideling it smokes a little blue smoke. Also i still need to retork the bolts and the oil returnline is leaking oil. 2 questions, any ideal what the smoke is still from, and does a fuel cut stop the car from going any further on the rpm, when i get on the gas and floor it, the car will stop and shake kinda when i get at like 5k?

Blue Smoke=Turbo
Fuel Cuts happening to you too...

Different types of oil will burn and have different color smoke. Most Mobil-1 synthetics typically burns greyish to sometimes white with a faint shade of blue, where some others (especially the dino oils) will burn pure blue. I would check all your feed/return lines, however they have little to do with what's coming out of your tailpipe. If it's oil (or coolant) that is coming out the exhaust, that means that either oil or coolant has managed to seap through the center cartridge through the seals, and made it's way either into the cold side (to be burned through the combustion process), or directly burned on contact on the turbine side. Your seals may even be perfect (since you indicated minimal shaft play), but there could always be the possibility you can have some minor imperfections (and even hairline cracks) in your center cartridge.

BTW, I'm new to this forum, nice meeting you guys.

Fixed the problem, I just had to clean the intercooler pipes, and just wait and let all the oil burn out of the exhaust, becuase the old turbo died and blew oil all over.
