Leaking Injector

I found a 2000 7.3 power stroke for sale on craigslist that I like. He is asking 5k, it has 243k miles, rebuilt trans, tuned, but he said there is a leaking injector that was diagnosed at a ford dealership. How much would it cost to replace the injector? Is it bad if the truck was driven with a leaking injector?

Could easily mess up the piston, but replacing an injector is actually kind of easy

About how much would it cost to have a mechanic do it? Is there any way to tell if the piston is messed up from the leaky injector? The guy said it smokes while its running.

If you did it yourself, it would be 1 injector + o rings, not sure what mechanics charge these days, but roughly $300 if everything came from ford or such

Is it a bad injector or just a leaky injector oring?

PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.

Leaking oring won't cause any permanent damage, but could cause a no start or hard start issue, especially when warmed up.

An injector stuck open would dump fuel in and could burn a hole right in the piston. This is far less common though. 7.3 injectors don't seem to fail in that fashion very often

Ok I will have to try to find out more information from the guy. Is there any way to tell if the injector is stuck open? He said it smokes while it runs if that helps at all.

if there was a hole in the piston you would have blowby. search youtube for "7.3 blowby" to see how to check it.

243k and unknown if replaced, i would replace the injectors. a good rebuilt set is about $1300. you could probably find a shop that will charge $400 to replace them and find another that will want to charge you $1000

it's not that bad of a job to do yourself. the hard to reach valve cover bolts are the worst part.
