I plan to change the unison ring and clean my turbo after 10 years of trouble free service. I had a minor hiccup not too long ago, but it has since gone away on its own.
I recall when I cleaned my OEM many years ago, I used anti-seize in various locations and ran it for a year before opting for the KC unit.
I contacted KC directly inquiring about anti-seize use.
Their response:
We do not recommend using any anti seize, just use some pb plater on the vanes and ring and that's all you would need.
The anti size together with the soot will just gunk it up right away.
I am taking their advice since they build these things on a daily.
Just food for thought and wondering what you guys do when you disassemble and clean?
Trust me that is my natural instinct to use anti-seize.
I will use it on the case but I think I will take their advice considering they build, assemble and re-assemble without using it on the vanes or ring.
I am curious to see once I disassemble if any anti seize was used. It has been sealed and untouched since I installed it a decade ago....with zero issues to date.
I use the high-temperature anti-seize, but a small amount, and work it into the 'oxidation pores' of the metal. It's hard to tell it's even there on the surface and pins. The International rebuild kit comes with anti-seize and instructs you to use it there. I don't care to use a lot after rebuilding two turbos.
I’m sure it doesn’t hurt to put some high temp stuff on there, but I can’t imagine in that environment it’ll stay there long until it’s carried out the exhaust pipe. So I’m sure it doesn’t hurt, and it’s doubtful after a few good heat cycles that it helps.
I wonder if caking on anti-seize mixed with the soot PLUS the oil mist from the CCV (if still in place) would make for a headache.
I'll report on the internals of my turbo once I break into it later this month. I probably wouldn't be in a hurry to do this but I have that damn 8yo coolant pipe on the firewall, requiring R&R that sprang a drip at the crimp. PLUS the BD up-pipes I installed that I know rub on the stud for that particular pipe.
I still can't believe it happened to me
If I didn't have the newly installed turbo blanket on, you bet I would have seen and/or checked that. That turbo blanket makes an already hard task that much more difficult.
I will say this but not to hijack my own thread, that turbo blanket works. I can literally touch the turbine with a bare hand after the engine has been allowed to come up to temp.
Does it really benefit performance....who knows, but it keeps that heat from radiating out.
