Was going to pull the retainer on my pre-combustion chambers,yesterday to check and replace seal. I have been told this could be the source of my anti-freeze entering my cylinder.
well I got the tooling, pulled the injector,buy the way looked like anti-freeze on top of piston looking into the little hole. Anyway clean threads installed insert then big bolt,started screwing it down with
3 foot handle. When it started pulling hard the whole retainer just spun, instead of lifting out. Try to wedge bar between head and retainer,but could'nt hold it. Wasn't going to pull intake manifold, but might be able get better leverage on hold retainer. What am I not doing or doing wrong. Thanks Rick

Might try to clean threads again and/or put something on top of the little rod/spacer you put down in where the injector seats before you screw the bolt into the retainer. I wouldn't go crazy, maybe just a flat washer, you don't want to ruin the threads by only just having it started when it begins to pull it. If a washer makes it come up just a bit, but it still stops, then remove the bolt and add another washer or two to the stack and tighten again. It really shouldn't be that hard, at this point it's just the o-ring stuck to the head that's holding it.

You could use an impact wrench (with a little care).

Alternatively you could just remove the whole chamber, retainer and all. Have you drained the coolant all the way down?

I believe it is far more likely that the problem is with the chamber or the copper sealing washer underneath it than the retainer o-rings.

Thanks ccjersey,the washers done the trick. I see what your talking about of having to pull the chambers.could not budge them with a 4ft. handle,will get longer cheater,and try again. By the way, when I was in high school I used to help milk about 22 Guernesy's and a Jersey or two. Dad always wanted to save milk for house out of one of the Jersey's.
