Compression Question????

[thehermit]

Yea...Unfortunately

80 psi: note verticle grooves:



Pull piston: note stuck ring and more vert damage


120 psi: Cy; deglazed with hone 90% of vert grooves gone, cross hatch re-established, comp back up to 120, motor is happy again. Thes pix were about 3/4 thru...it looked a bit better when cleaned. I put in a new cly and ring kit. Rod and needle bearings too.





It dosnt make me feel good that I had to perform surgery but like Tim has said these motors are tough and basic and it didnt seem to mind the work. My motor was a nice clean motor that I aquired for cheap money before I gooned it up. I hope to get a few seaons from it still.
