Blue Smoke-Tdo6 kit just installed

[huntin5L]

Well, this kit was just put on. It was a used kit that I purchased from another member here and it seems to be smoking a lot. Usually it is between shifts or after getting on it and then stopping i can see it, more so at night, but i can see it during the day too. My car definitely did not do this before the turbo upgrade and was wondering if I may have caused this, maybe the seal went bad? When putting on another turbo, do you have to hold the turbine on the initial start to get the oil circulated, because i didn't do that and was wondering if that may have caused this. I was on my way home after the install by my dad's neighbor and about 2 miles down the road i noticed in my mirror a big cloud of blue smoke in the person's headlights. I was gonna pull over it was that much smoke, it scared the hell out of me. It seems to be getting a little better, but still seems like a lot. I have the right size oil feed return lines so i know that isn't the problem.

By the way my car seems to backfire a little bit in the exhaust between shifts too, probably running a little rich too.

a tell tale sign of blown turbo seals is, boost let off, and then boost again. if it puffs out a nice cloud of blue smoke, chances are you have blown seals.

I bet your running atmospheric BOV?
Does your tubo have shaft play?

Where is the drain?

 

[huntin5L]

No atmospheric bov. Im not a ricer or running 1000hp no need for bov. The turbo has very minimal play. As far as boost let off are you saying that the turbo kicks in and out when you are boosting? If that is the case it may do that a little, i noticed it a bit yesterday. IJ what do you mean by where is the drain? Also, this thing has been getting a lot better, but still smokes. I need to get a video of this happening i may do this tomorrow when i have the time. Thanks for the posts.

no you do not hold the turbine or compressor wheel during startup. i dont know why people do this, i think its a bad idea.

you are supposed to prime the turbo tho. usually you add oil in the turbo at the feed line to get some in there. then while you have the oil feed line off, crank the car (with efi fuse removed) until you have oil flow thru the feed line (be sure you have a can or something to catch the oil once it starts flowing). then reinstall the oil feed line.

what IJ is talking about is the oil drain from the turbo to the block. if this is kinked, too small, or routed incorrectly it will prevent oil from flowing out of the turbo fast enough. if thats the case, thats the oil that is burning.

I see, the oil drain line is pretty damn big and I doubt it is kinked, but i will check. Thanks, Bob.

does the drain go straight down?
no u shape?
sounds like blown seals.
it's a good idea to prime the turbo before initial startup.
usually you put oil in the feed of the turbo and spin it around a bit, or take out the efi fuse and prime the turbo for oil pressure.

 

[huntin5L]

Damn, i didn't do that, i did let it run for 10-15 minutes before i took off

Hope i didn't f anything up.

Where does it return to?

Any PCV mods?

 

[huntin5L]

No pcv mods whatsoever, it returns to the oil pan :dunno:

 

[IJ.]

Into the bung on the side?

 

[huntin5L]

I believe so, i didn't do the install, i had my old man's neighbor do it.

Damn IJ i just posted this, your fricken lightning when it comes to replying

Too small a return will make an old school turbo smoke like a bitch.

 

[starscream5000]

What are these "turbo seals"?

Is it possible to get a larger line to get the extra oil out fast enough, and then it will stop the smoking? I though I had heard that somewhere by one of the more reputable members on here before... :dunno:

 

[huntin5L]

I don't know what custom size it is but it is big.

 

[starscream5000]

Is it pretty much shooting stratght into the block? Like a 45* or less path?

 

[IJ.]

Fluid dynamics.... it will only flow as fast as the point of greatest restriction in this case that's the small port in the fitting that screws into the pan...

You can get away using that as a return with a BB turbo as they have internal 1mm restrictors so flow bugger all but older journal bearing turbos pump a load of oil so you need minimum 9/16-14mm as a return if not larger.
