I am currently refreshing my 1HDT before swapping it into my FZJ80. I pulled the injectors and sent them out to be rebuilt. Upon pulling the copper seat washer out of #2 I found that the previous idiot that was in here had some trouble getting that washer out and marred up the seat in the head pretty bad.
I drove this motor for a while before I pulled it and it ran great. Compression was good and leakdown was correct. I did have a hard time pulling the injector on #2 and now I’m guessing that the washer was leaking ever so slightly and maybe coked up that injector seat enough to make it come out hard.
The question now is how to proceed. Is there a method to clean that surface up a bit with the head on? The copper washer was sealed on there pretty well like this before, so I’m hoping a very little smoothing out could make it function fine. Best way to do that?
Also: how tight are the tolerances there? Is a thicker copper washer an option?
