Alright guys I've got a 1984 om617 out of a 300sd stuffed into my 1984 Jeep CJ7. I've been fighting some pre-chamber issues for a little while now and I'm not really sure what I should do next to resolve the issue.
So a few months ago I noticed inadvertently (like most people) that #2 and #3 prechambers were leaking after I had bled the injectors and fuel collected down at the pre-chambers. Okay no big deal I bought new sealing rings and slammed them in easy peasy. I thought I'd done a pretty decent job cleaning the carbon off of the pre-chambers and seal surface but apon reassembly I took my 2 leakers and turned it into 4 hooray. So it came apart again and this time I was meticulous about the cleaning. Another thing to note was the first set of pre-chamber sealing ring were Victor Rienz brand and when I was inspecting them after I pulled the pre-chambers was the quality seemed to be somewhat lacking so I bought Mercedes OEM sealing rings and the fit and finish on those were top knotch. Everything looks good I didnt see anything out of the ordinary with the pre-chambers or the head and the pre-chambers dropped in with out any coercion required. I torqued the pre-chamber collars to the required 180nm. Fired it up and it still has leakage coming from #2-#3 after a little runtime #3 seemed to seal up but #2 still leaks. I brought it up to operating temp hoping that maybe with some heat it would seal up but no love.
Has anyone run into this problem before? Any ideas on a solution to this I've run out of ideas except to do a hot re-torque? Any advise would be greatly appreciated thank you.
