HELP! Why are my new turbos smoking???

[hitman17]

Ok, here we go again. Someone mentioned that it could be a bad shaft causing the smoking. Here the statement that's been made.

"I don't recommend rebuilding your own turbos because usually this is what happens, your out money and now asking is it my turbos? even if they did balance the turbos you have to have them aligned the same way they did on the balancer, did you send them the thrust setup and shaft nuts?

if not then you can reassemble and clock them the same way they were not sent in with them, and then you have to make sure they are now aligned properly. plus on td04 the tollerance on the shaft is .0003 i doubt you have the tools to see if the shaft is stll within wearable limits, and only .0001 on the straightness. along with a bunch of other variables on ring limits and clearances".

Now the alignment and balance were done after the rebuild, so I wouldn't think it would be that, but I wanted to ask you guys. What do you think?

It's a gamble rebuilding your own turbos. I did mine and they lasted quite a while but not as long as they should have.

Yes, but I highly doubt that fresh rebuilt turbos would be burning oil at idle especially if they have barely been run/never boosted once.

[hitman17]

So you think the turbo might be bad?? The rebuilt was pretty simple, just taking out some old parts and replacing them with new ones. The alignment and balance were done by Forced Performance. They replaced the turbines as well.

Well they shouldn't be smoking anyway unless they are cracked or something. You would be smoking out the exhaust.

[hitman17]

So you think that it's just burn off? It's not smoking out the exhaust. If the shaft is bad, can I cause any damage by letting it run idle for 20 minutes, drive for 10? I figure that should get rid of most of the burn off, but I don't want to damage anything else. If the turbo is shot it's shot, I don't think I can do anything to it that a rebuild wouldn't fix.... right?

Yeah I think you are worrying too much (I really don’t know how much smoke you are talking about though). I’d grab the fire extinguisher and take it for a spin.

I'm assuming you didn't modify the oil lines? cus stuffing with these can cause too much oil flow which will force the oil through the bearings and it will smoke.

[J_Parker]

Try some thicker oil, if what Joe is saying is what's happening, the thicker oil with subside the seepage through the bearings just enough to guage a difference, and put a prognosis to the problem. That's how I discovered the turbos were gone on my Soarer.

I agree.
