Well, the outdoor season is over here so i have started to clean everything up including my GO .21 5P. Its on my work bench in parts and i think everything looks ok, i did notice a few races back there have been alot of dirt build up at the front of the engine which i assume is a leaking front bearing ?

Now, the question is, is it worth it to replace both bearings, o-rings and maybe even piston, sleve and connecting rod or should i just get a new engine for the next season ?

How about just getting the sleve pinched ? Ive been looking around on prices for parts, and if i replace things to get my engine back to " new " its almost as much as buying a completely new engine, so whats your opinion ?
