Hi I'm helping restore an m6 bomb service truck it was previously mentioned on here in June 2013 belonging to J Duncan. I don't think its been touched since. I've been lead tech on 3 gmc cckw 353 g508,s in the past but the chevy is a new beast it has an original 235 fitted everyone I speak to has the later 235 full oiler fitted or a gmc 269 we've got the 235 running and Ive done a full set of tests before we strip it down, it did have 2 stuck valves on no 6 cylinder as the cam followers / tappets where initially stiff I could do with some pointers as I don't want to tear into the crank trying to achieve unobtainable readings if what we have is good to keep running with. I am 46 and was formerly trained in college as an automotive engineer, then working till 2013 at a ford franchise, now I work for myself, I have learnt in my time that shop manuals Are important but do not always tell the full story.

Nice to see another G506 truck. Looks like it still has the original BV military 235 engine. Have you prelubricated everything before attempting to start? There is a good tech tip on the home page. Good luck with the rebuild, looks like a very good candidate.

Check the valve guides to make sure they are free, otherwise bent pushrods can happen.
