N14 cracked head or bad Injector Oring?

Honestly, I've never done it on an N14. Always just replaced injectors when I narrowed it down to that.

I always tried to think of the customers money and downtime. So R&R an injector and know it's gonna be good to go, vs trying a repair? I always went with the sure thing.

I have replaced them on 60 Series way back. Replaced one on my truck with a used one I had in the truck to get back to the house a few months back. It's easy on them

 

Just asking, cause someone out there is rebuilding them. The right replacement mechanical parts and a high quality replacement solenoid and a guy, might be able to rebuild them his self. Wonder if the solenoid is soldered in? I bet you, if it is and you can work on your own cb radio, you can rebuild your own injectors. Gotta find the supplier who has the best solenoids. Never been in one but I bet they’re not very complicated.

 

I'm sure you could, i just don't know if it would be money well spent. A guy who has plenty of time to tinker and enjoy it, maybe.

I want to work more, to make more money, to afford what I enjoy. Which doesn't involve trucks. So the quickest fix, and best quality fix, is what i'm after.

I don't want to do it at all, so I do my best to make sure it's right the first time.

 

I hear you. There’s plenty times I’d rather be running lines for flathead or chasing gobblers, ducks and bucks. With as much junk aftermarket parts are floating around, I just thought it may be advantageous to try it, if a guys got the time and know how.

 

Who do you trust for your source for new or rebuilt N14 injectors?

 

Just call up a local injection shop. Had a few rebuilt recently for a relatively uncommon European engine and they did it for less than buying new. Heck of a lot more N14 engines out there than this one I was working on.

 

You are correct. Good parts are hard to find. I've always preferred OEM, but they're questionable anymore too.

It's been two years, but i had the best luck with Fleetprides aftermarket injectors. Maybe i had just a bad run, but i've seen the same N14 injectors replaced twice in a year that came from Cummins.

I put a new set of Detroit injectors into my last truck before i put it on the road. Over two months, three had leaked fuel into the oil. I pulled them all and replaced with Fleetprides, and ran them without issue for 8 months, until i blew the engine.

Not sure if they are still using the same supplier.
