Have you tried Decalin ? It is designed to scavenge lead and what I use when I can't get the auto gas. I have no idea what if anything it might do to the turbo

[GraemeSmith]

Decalin is TCP - Just in a buffered solution with an easy to use dispenser. Same active chemistry as the brand "TCP"

[tx_swordguy]

That may be but the TCP in TCP is 10 times higher in concentration than it is in decalin. TCP also has toluene and other chemicals that may play a part in why it is causing problems with the turbo. What ever the case, not using the TCP seems to be helping the issues with a stuck turbo.

My turbo seized because of rust. sonex suggested trying STABLE FOGGER. So I added a port on my exhuast aimed right at the vanes. I"m at 60 hours now and have forgotten to use the fogger with no problems...

We believe it’s more about humidity and surface rust on the cast iron housing that occurs when a newer turbo sits around for long stretches of time without running to burn-off the moisture. If the turbo is run/flown more often, it seems to be less of a problem. This is actually a service bulletin for turbocharged Continental engines dating back to 1971, and for Tornado Alley Turbines aircraft engine conversions:

We make reference to the above service bulletins in our AeroVee Turbo service bulletin ACV-SB-091616-1B: http://www.aeroconversions.com/support/aerovee_sb.html

Your turbo has no damage to the bearings or other internal components.
