Pulling the head on an Onan DJC Generator

I have been debugging an Onan DJC, 4 cylinder 12KW, air cooled diesel generator. In chasing down a rough running engine when cold I just heard the unmistakable hiss of a leaking exhaust valve.



I have not torn into it yet to pull the head and do valves or even to check clearances yet. I have to do that. Anyone out there with some experience on these engines? Are there any tricks or suprises to watch for.



Thanks, Bob

and never pulled its head, so my experiences are not very relevant to you, but I have a couple of simple suggestions.

  1. Buy a repair manual for your generator, check out ebay seller n2gravely, he has one, and he is a good guy.
