Injector Question?

[05F350Lariat]

So among other things I replaced all the injectors in my truck with a set of 175cc 30% from Sheldon at Renegade Diesel. After chasing a few other problems I finally got the truck started and it idled great for about 45 minutes. When I tried to take it for a drive something went wrong and it started spewing smoke. I got the truck pulled over and shut her down then had a buddy tow me home. The next day the motor wouldn't turn over and after some reasearch found out the motor was hydralocked. Due to finals, the holidays and family visiting I had to put off the truck for a little bit. Today I got to pulling glow plugs and found what cylinder was full of fuel. After pulling the injector I found the copper seal messed up and the lower o-ring was dystroyed. My question is would I be ok to just order a new set of o-rings and copper seal or should I have the injector looked at to make sure it's ok first?

Should be. That could have a lot to do with torquing the injectors down too. I know when I got mine from Jesse at Warren Diesel, there were instructions specifying torque values based on what size Torx bolt you had holding the injector down. Get rid of that fuel, reseal that injector and make sure you torque it properly and give it a whirl.

Sounds like someone didn't tighten their injector hold downs tight enough (or at least one anyways). Just replace the seals and give it a whirl. It should be good.

Out of curiosity, what injector was it? Best of luck for sure.

second injector on the driverside so I think it's #4.

Yep your right this is very common when the hold down bolt hole fills with oil! then they tighten the bolt and hydrolock the bolt but the injector hold down is loose!

Agreed 100%

Yes that's #4. I'll try to get all the numbers Jesse provided me but the one I remember is this one (because it applied to me). I had a T40 torx holding my injectors down and his instructions called for T40 to be torqued to 31 lb/ft. The rest of the instructions specified if you had a T30 torx hold down to use 12 lb/ft. That sounds a little light, but those are the instructions from Warren Diesel. Hope this helps.

Thanks for the help. New seals are on order and I'm hoping to finally have the truck back on the road this weekend.

i did it once to. just make sure you push all that old fuel out. and when you start it back up it might smoke for awhile but it will be ok its just burning off the fuel in the manifold. way i pushed the fuel out is take the starter wire and jump it off the battery for a split sec. stay clear of the piston area because it will force the fuel outta the hole fast with pressure!

I thought ford spec is 24-26 ft lbs on the injector hold downs?
