Injector Tick or Something else?

I recently purchased a 2002 f350 7.3L. It seemed that it blew smoke on startup (it's cold here, but does blow alot of smoke) until it warmed up for a few minutes, and has an loud anyoing ticking (almost like a rod knock, but not quite). The motor also had a miss in it a little.

I failed a contribution test on #8 cyclinder, so I replaced the injector yesterday. The engine sounds smoother, and has plenty of power. Runs great, still blows smoke on startup. But this ticking noise has to give. Can injector cackle be this loud? It starts up fine, after 3 minutes the cackle begins. Is there anything I can do to help make ti quiter? Thank you.

Did the noise go away with any one cylinder off-line during the contribution test? If so - you may have a cracked tip on that injector - if not - you could have a bent push-rod. Both are fairly common causes of the noise you describe.

RockAuto has them for $3.31 - the valve cover gasket is re-usable so if you figure out which one is bent, it should cost you $3.31 and about an hour of your time swapping it out. SEALED POWER Part # RP3345

what was the code on that injector???? the other day a mechanic pulled my valve covers and we looked and all the injectors had an AA code which is hte injector code for 94-98 PSD's and we looked at the number 8 injector and it also said AA. the prolbem with this was that the number 8 injector has to be a AE not an AA somethin about a long lead injector. so basically it has to be different for fuel reasons, and if u keep an AA there it will bre really noisy and rakety, it'll run but its loud and annoying.... so that might be ur problem, from what i understand its pretty common

Partially true - The AE was introduced in 2001-2002 production run as the long lead injector for cylinder 8, while 1-7 were AD injectors. AD and AE are split shot injectors - AA's are single shot. You couldn't mix AA and AE in any way, shape, or form.

They require code AE injectors in the 94-98 PSD's on cylinder 8. its a common misconception and idk if they are split shot or not, i dont think they are.
