Both times I did injectors in my LB7 they came out easy without needing a pry bar

I also didn't pull and reseal any of the cups. Didn't have any leaks. With that being said, most here will likely agree that pullimg the cups is the best idea

The way I see it, if the injectors come out easy, itís highly unlikely you disturbed the seal on the cups. All 4 on the easy side came out easy, still got Vaseline on them from the injector change number 2 done 200000km ago.

One thing I noticed is #5 came out with absolutely no soot or carbon on it. The other three all were carboned to some extent.

Looks like you are making good headway. My injectors has little to no carbon on them too.

Just a little twisting and pulling and popped out. Put one of the injector lines on as a handle to pull on while twisting

Check / adjust the valve lash while you are in there

All out. No cups came with and all the injectors came out fairly easy. The back 2 on the D/S needed the injector line handle trick but werenít too bad. Need to find one injector harness that I found zip tied together at the connector, injectors and some seals and do it all in reverse.

Ya was going to spot check a couple at least. Almost 160 000 miles on it. By the looks of the oil inside the hot pipe it looks like it might be needing a turbo soon also.

Core injectors sent out. Iím going to try a shop in Quebec that does a lot of common rail stuff so I can get a quick turnaround without having to deal with duty and customs charges. Will see how they turn out.

Unless they are a Bosch certified remanufacture then donít waste your time and money.

Not sure what their credentials are. I just know a buddy has used them in the past for stuff and they were good for him. They do mostly Bosch only and also are a training facility. For the price time frame and considering this truck isnít hanging around once it goes back together I figured it was worth a shot. Canít be any worse than pensacola.

Just remans going in. Not keeping this truck for long.
