I have one cylinder that concerns me more than the others. It's the number one cylinder. When I changed my injectors, it had alot more carbon build up than the others did. May be nothing, but it concerns me. The engine runs great now after the new IP and injectors so maybe I should just leave well enough alone! LOL
Was that cylinder missing a copper ring at the bottom of the injector hole?

John I can't remember, I know one of them was but I can't remember if it was that one or not. One of them only came out with half of the copper washer, I don't have a clue where the other half went but it wasn't in the bore!
I would not think 3500 hrs is that much time I have seen 6.534 120 hp perkins run 18000 hours under full load and a 65 kw light plant on a boat go 72000 hrs and it was not burning much oil . But I allways do short changes 150 to 200 hours on the perkins it doubled the life of eng from 9000 to 18000
