Changing my injectors.New ones ready to use out of the box???

I forgot to mention, that i used a touch of never-sieze on the threads before I Torqued them into the heads. I also had a spare fuel line and tested one outside the block to see how it atomized. It really is not much to see, but dripping can cause puddling on top of pistons after shutting down...that is a real problem of another type.I am very much aware of how fuel can enter the skin, and damage it, but neglected to mention it to warn you. I have been working on diesel gen-sets for years..CAUTION,,Our pressure on lines is 1400 psi, new ones is higher..Protect your eyes at all times...

I'm with Raspy on this one. Please do not pull the injectors to watch the spray pattern. Atomized fuel will easily penetrate your skin and does nasty things. If the injectors are hanging from the fuel lines, there is no telling where that fuel will go, and if you are close enough to inspect the spray pattern, you are close enough to get the fuel injected into you skin.

The fuel line returns are an annoyance. But the bubbling injector may have a cracked body, which will not allow full pop pressure at low speed.

Since you have the injectors, why not try replacing that one first, button it up and see how she runs? Since these are new, I'd replace all of them, as one new injector and three old ones may throw the balance off in the injection system and each cyclinder. But its a good test to see if you "cured" your problem.

I had no idea atomized fuel was so dangerous. I'll do like you said and change the one injector first. I figured changing all of them cant be a bad thing. I dont know much about diesel engines but Im assuming that fuel must be really high pressure if it can enter your skin. Thanks for the tip.
