Dino,
in the past two weeks, my RS5 had killed 4 of my turbo plugs. Just yesterday it killed my last turbo plug. I think the .3mm shims you suggested are too much pressure for my plugs to handle.
The piston and button looks rough satin finish like.
My engine is now dead

. The last plug lost its filliment inside jamming the piston and my piston is no longer useable.
I need to replace the piston, sleeve, and rod. Would you be able to get me some parts.
I want to replace it with a RS3 piston, sleeve, and rod. Do you know if it will fit or do I have to get the RS5 set.?
Do you know if the RS5 piston and sleeve set on calandra comes with a rod too? I can't find the rod by it self on the list of parts.
I am bummed that my experience with STS engines didn't turn out like I wanted it too.
