There is not a problem with getting them out. Take off what you need to get to the valve cover. Take the valve cover off. Da-da. There they are. 4 little bolts and a wire harness and those babies are outta there. Simple, Huh? Yep, even a truck driver could do that, right? Yep, but they have to go back in. No problem. Just reverse the removal process. Right? Well you would think. But wait, did you know that when you pulled the injectors out, oil has run down on top of your pistons and when you put it all back together and hit the starter, that oil has to go someplace. Well guess what? It tries to go out the exhaust, but there is too much in there. So what happens??? Well, in my case, it just bent three of the rods before it locked up. And you don't even want to know what that cost. I was sick, mainly cause I did it. Plus, Cat recommends replacing the 4 bolts per injector everytime you remove them. So, if you aren't for sure what or how to do it, do like I do "now". Take it to somebody who does know. I saw another truck that only had one injector removed and replaced and it too had a bent rod on that cylnder. So it is pretty common with the 3126 if you don't know how to do it. As for your problem, there are cups under the injectors on a 3126. They wear and let fuel in water or oil. Be smart. Pay the price. Or be prepared to pay more if you do it yourself. Me? I do external parts only now, but will not attempt internal again. Lesson learned.
I guess. I think there is about 4 or 5 on each injector. Plus some kind of a hard fiber washer looking one. I have yet to find one thing for these engines that was reasonable price wise. I was sent to pick up an idler pulley for my truck at Thompson Greene Cat in Nashville. They are strictly wholesale and sale only to dealers (unless you know somebody). Anyway, the bill was made out to a Ford dealership in Nashville for $14 and some change. 3 Days later after the bill had been sent to another dealer and finally to my repair man, it was $220 to me. Now, I have found out, if you have a part number, you can cross it to Dayton idler pulley and it is they who make them for Cat in the first place. $15 online. What a rip. This is why I put truck repair shops right up there with lawyers and bankers.
This is not a seal problem! It is a injector cup problem. The cups need a special tool to be replaced. I just went through this in Dec. Any good repair shop can fix this. Cost was $500.00 all new cups and injector seals since they had to come out. Good luck
