hi all,
hope somebody out there can help
i have previously re-built my bottom end with a crank regring which was 0.25 for big ends and 0.5 for mains complete
set of bearing shells new oil pump higher rated spring and pump drive inc arp bolts as the bottom end was nocking , it was rebuilt and has run quiet and trouble free for about nine months now , until one day she started to missfire badly only running on 3 cylinders found cylinder no1 to have pool of oil sat on top of piston and chucking out blue smoke from the exhaust i have removed and stripped the bottom end to find the rings need replacing (my own fault should of changed em 1st time round) and much to my concern the new big end shells are showing signs of wear (COPPER SHOWING) it also was running low oil pressure when she started smoking
help..........

if uve caught it in time then i would have the crank polished !
not the same as regrind as it wont be scored then put in new shells etc..same size as before have u had the bores honed? then new rings , oil pump etc..... then should be good to go!!!!

unless u go for a full rebore new pistons and rings !!!

while its out do it properly?
