Injector O-Rings
OK Guys, need some advice. I was talking with a diesel mechanic and he said that over a period or time, (unknown to him) that the injector 0-rings need replacing. What the heck is he saying? What simptoms will be present? And finally, if I ever them, should I at the same time replace the injectors with better ones and would the HPOP be able to supply the fuel with performance mod injectors?

Injector o-rings can degrade to the point they need replacing. Initial symptoms can be a really dark, oily fuel filter, but that can be decieving because age can do the same thing to the filter. When an injector o-ring fails it is normally accompanied by a loud knocking from that cylinder as well as heavy smoke from the tailpipe.
Bad o-rings does not neccesitate replacing the injectors with performance versions, but if you do change them the type of injector will determine if the HPOP can flow enough.

Thanks Cookie88. I am sure my O-rings are fine, at least at this moment, but I just want to be ready and to what to look for. I am replacing my fuel filter this week and will make a good inspection. My exhaust is of good color. Thanks to barebackjack as well.

This, I feel, is a very good question. I had 3 bad injectors, and bad o-rings on two others, while still under waranty. I was wondering when to change them out, maint. wise. I guess it's just kind of a wait and see game.

No light. Just went to start it, and it just cranked. Replaced both of the batteries, talked it over with our new Moderators, had it towed in.
