Stihl 088 wrist pin brass bushing

[Kebo57]

I bought 3 saws none runners £100
Stihl 017 easy fix sold on £120
MS660 crushed all most brand new though new tank and 1/2 crankcase + some bits £200 keeping it
The other one was a 088 been stood with no barrel our piston small end rust pitted and .004” over sized (no barrel our piston)
I’ve press fitted a brass bush in the small end with oil groves bought a cheep bolt on cylinder & piston modified the clip on ally muffler to suite the bolt on barrel,
The 088 is running my question is
How long will the brass bushing in the small end last ?
I have pic of the mod to the muffler if theirs any interest
I’ve proved the saw worthy of a new crank

bushings need a oil bath or pressurized oil supply if under a load, might last a hour before making unhappy noises...the real issue is where the wrist pin goes once unhappy
