Being serious..
[486] ............ I just now noticed that "winky emoticon."
Well, this afternoon, I did check a Turbo I have on the bench. My little long skinny fingers will latch onto the end of the Turbo shaft ..
Okay, here's an interesting thought. There have been several discussions (Threads) about Turbo rebuilding, rebuilders, do it yourself kits, etc., with lots of naysayers and supporters on both sides. Primarily the naysayers thought is that any kits would be CRAP (Chinese Replacement Auto Parts) and that the rebuilders would not do a "proper" balance (both static and dynamic at high speed).
Anyway back to the thought ...... Doing a "chemical clean" without removing the Turbo, in my opinion, is risky from a balance stand-point. How do you know whether or not the OC resulted in a uniform cleaning.
Let me clarify. Did the OC leave some junk sticking to a few of the Turbine blades? Did one side of the Turbine receive a better cleaning than the other side? If your guess is, probably so. Then, don't you think the result is a Turbine out of balance? Keep in mind, the VNT15 spins up to 200,000 RPMs, thus, the need for that perfectly balanced assembly..
In my opinion, proper cleaning can only be achieved on the bench with the CHAR removed from the Exhaust housing ..... The crud in the Vane mechanism can be unbelievable as demonstrated in the pic below. (see my photo gallery link above)
Below, that same Vane assembly after cleaning.
Again, there are lots of pics in the link to my photo gallery posted previously in this Thread.
