valve problems and gas flowing

(1/1)

royceymon@hotmail.co.uk:
Just had new rings on the wiseco, 52 hours and pistons still mint ,shame the inlet valves were not! one had a chip and another large bit just about to drop off put some crack dye from work on them the white producer and hey presto a crack ! the other was getting undercut .
whilst doing it i thought i would take a bit more material out of exhaust ports with the die grinder ,just need to finnish it off with a polish!!
