Don't you hate that moment when you put the upper valve cover with a bead of silicone on and reach for the torque wrench and see that you left the plastic cap on the injectors. Man, that SUCKS!

at least you didnt put in a CP3 and find a oring laying on the ground the size of the CP3 oring and you already half way put the engine back together then pulled it back down to find the oring on the CP3 and the one on the ground came off the old fuel filter

shiet. the stories i could tell about putting stuff together and having to takeit out and put it back together.

how about 3 lb7 injector jobs in 6 weeks on the same truck. i got really good a changing cp3's i was able to do mine in less than an hour. but i did have a highly modified engine wire harness and fuel system

Default Injectors are in!!!!!!!!!!!

I finished installing my injectors yesterday. Today I will attempt to get everything put back on top of the motor. Hopefully I remember where everything goes. I should get this baby fired up today. Check out the 2 injectors in the pic. I guess those o rings were the cause of diesel in my oil???? None of the cups came out, the all were still flush with the head. My question is this........would those o rings have gotten damaged during install at the factory? I bought the truck with 14k miles on it and it has never had injectors replaced. I have 200k now but started seeing grey smoke at red lights at about 170k. How else would the o rings get like that?
