VGT Actuator Piston Seals
This is my first post with you guys. I have been doing a lot of searching and have not been able to pinpoint an answer to my question. Hopefully I can find some help here from some of you more experienced individuals.
Problem at hand- while disassembling a friends Garrett gt3782va turbo which has been giving him lots of problems, I found that the Actuator Piston for the vanes is missing both of its oil seals. I have been looking all over online for either the seals or the complete piston assembly and have not been able to find anything.
Also with these seals missing, what effect would it have on the function on the unison ring?
And one last question, with a new quality Compressor wheel and Turbine wheel installed will the balance be way out of whack now?
Turbo Information and brief history
*Turbo has a Remanufactured sticker on it but Owner stated he has never had turbo serviced and has owned truck since new. Dealer has performed many other repairs on truck in the past though.
