Need some help with a Knock!

[RobertP]

About three weeks ago I had and injector body crack while driving. Pulled off to the side of the road, after noticing a bad fuel smell. Found the oil level way over full and the under side of the truck soaked in fuel and oil, from the breather. Pulled the injectors sent them out. Replaced the cracked injector body and got some new nozzles put on. Reinstalled all of the injectors changed the oil. (Drained out about 7 gallons of oil and fuel mixture) started the truck up idled perfect nice and smooth no smoke at idle at all. Drove up and down the street noticed a what seems to be a timing induced knock. Starts as soon as there is a load on the engine and is completely gone by 2000 rpm. Programmed the ecm back to stock the noise lessened but was still there. Once again I sent my injectors out to have them tested all tests come back golden. (Again I have to thank industrial injection for putting up with me through all of this) I got my injectors back again today and installed them. Knock still there, and gets worse wheni put the program back in the truck. Checked all sensors for proper connections all good. Drove the truck home runs great still has a ton of power runs and idles great still. Just have this annoying knock from let’s say 1300-2000 rpm then it’s gone. im at my wits end with this thing. Oh yeah one more thing I put a new stock cp3 on thinking maybe that could be the cause. Any and all info would be appreciated. Thanks Robert. Feel free to ask any questions im at my wits end with this knock.

sorry for the long post!
