Pump/Injector issue

[Tyee II]

I recently got my 92 F350 back running with a 7.3 with the Banks Turbo It ran well until recently when upon start up there is lots of smoke and a misfire until it clears out and and warms up. It appears that there is likely a leaking injector. The longer the engine sits the worse the smoking is. Once it is up to temp it runs fine with a little more smoke than normal with heavy acceleration. I am thinking leaky injector ? Could this be a pump issue ? If it is an injector, is there anyway to tell which one without pulling and testing each one ? If it is an injector, I am thinking repalce all 8, what brand are best and where is the best place to buy these ? Thanks in advance for your replies.

Well not easy diagnose but crack injector lines at first start up...whichever one seems make smoke go away is likely the one.

Fill in the truck specs in your sig line, this way we have a clue of what you have foing on.
Also hit the stickies.


First guess 'truck at least has 100k on pump and inj.

Prognosis = replace both.

Pump and injectors have been replaced about 60 k on each. I have a set of Stanadyne (E code) injectors from the removed engine that have 25 k on them. They were working fine when I removed the engine. I am tempted to install them in the new( to me ) engine. Any precautions I should be aware of ? Can the copper washers be reused ? If not, where can I find replacements ?

pLEASE DO not REUSE THE COPPER GASKETS ON THE INJECTORS. tHEY HAVE WORK HARDENED AND WONT SEAL CORRECTLY. tHEN HOT EXHAUST GAS WILL CUT THE COPPER AND RUIN THE SEAT. iT ALSO FILLS THE HEAD INJECTOR BORE WITH CARBON AND MAKES INJECTOR REMOVAL NEARLY IMPOSSIBLE. nOW IF YOU KNEW HOW TO HEAT UP AND QUENCE THE COPPER IN COLD WATER AND THEN FILE IT SMOOTH MAYBE.. jUST MAYBE YOU COULD USE AN OLD GASKET. i SUGGEST DOING THIS OMLY IF YOU HAVE SOMEONE WATCHING THAT HAS DONE IT. sO MUCH EASIER TO PURCHASE A SET OF COPPER GASKETS FOR ANY GOOD INJECTION PUMP REPAIR SHOP OR THE MEMBERS MENTIONED HERE.


Really sorry it is all in caps.. Fat fingers hit the cap lock and I type 2 fingers at a time watching the keyboard.. My bad but I'm helping others.. Not yelling honest..

60 k you might want to pop test a set first then swap em.
The best thing I've done to mine was load it down and run it uphill like a rented mule!
This thing sat all year for a 1k mile trip, so the pump got to sticking and this freed the governer up.
But yours sounds like an inj. Leaker/stuck on grit?!

Hes in portland, I can supply pop testing and an install kit.

See.. You are VERY close to Russ and one can't get a better offer than this.. Close by and has the parts and years of actual hands on experience on these engines.. And many other engines too.

Russ is a helpful guy. Got a rebuilt set of BB's and return kit from him and my IDI is no longer in danger of fubaring itself Runs sooo much smoother.
