617-951 turbo diesel
what is the correct valve to guide clearance, Haynes says service limit is .0041... just got my head back from machine shop and I think the guy set my exhaust at .004. seems a tad sloppy. what do you all think
also this did not have the heat shields between the injector and the pre chamber--- is it supposed to?? (1982)
