6.0 Powerstroke hydrolocked/stuck injector

We go through diagnosing a hyrdolocked 6.0

[@kingcuhhh5832]

Hey buddy I have a question if you could pm me personally. My injector number 8 on my truck is getting stuck open I replaced the injectors with 2 different sets even had the second set pressure tested and all is good I replaced ficm and ficm harness and number 8 injector is still getting stuck open. If you could help me I would greatly appreciate it because I’m tired of throwing money at it and not going anywhere with it.

My brothers 6.0 hydro-locked from stuck injector's a few times and he did same thing just blew it out and swapped the injector. Only catastrophic injector failure mine ever had I lost a tip and to swap the entire head. looked like Injector turned into a cutting torch and went Freddy Krueger on the valves

Yep, they will do that. Thanks for commenting and watching.

Sweet I have renewed hope and can now carry on with my trouble shooting. 05 f250 6.0 has the same exact issue doing the same exact thing . Awesome awesome man I thought my engine was toast .

[@AutomedicGarage]

It can damage pistons, rings and rods but not always.

[@calirebel1776]

Saved me a lot of time. The same exact thing happened on this 07 6.0 new injectors week later towed in locked up. Awesome video thank you for making it.

Sure thing bud

Excellent quality vid. Thanks

Thanks for watching

Great diagnostic procedure. How that cylinder’s rod didn't get bent is a mystery/miracle. Very fortunate. Thank you.

Let's give her a rip love it,thanks for the video my mann ...always down to learn more about the 6.0

[@robadams-jz8mo]

I got it I was going by in the truck it’s facing it I should know that I feel like idiot I hauled cars for 25 years lol

[@6nzchencho752]

Just went to work on a buddy of 6.0 and it did the same exact thing. A thud !!! I pulled the plugs and man didn’t it spit diesel. It was also black with oil ? Could it be a bad injector o ring ? Might replace all 8 since it’s got over 200k miles. Any tips ? The truck locked up again after I pulled the plugs the first time

[@AutomedicGarage]

Could be stuck wide open, cracked tip, could be because someone didn’t torque the injector correctly and is loose in the cup, could just be the oring, there’s no telling till you dig into it and see what you got.

Hey Dude, did you figure it out?@@6nzchencho752

I just had a possible injector break, It died on Me, when I came to a stop the smoke literally filled the cab and was bellowing from the exhaust. It was coming from it looked like where the up pipe meets the turbo. Not sure exactly. Having it towed Monday to a local shop- motor was just freshened up with studs, injectors etc. mine does have an EGR cooler, but it doesn’t smell like coolant. It smells like straight diesel, so I’m praying that it’s just an injector when I roll the motor, it still sounded nice and even so I am hoping.

[@AutomedicGarage]

A lot of times it’s not the injectors fault but the fault of someone not torquing the injectors correctly or even at all

[@cjhancock4290]

@@AutomedicGarage I am seriously hoping that it’s just a small error and I am not digging out my pocket book again, I have camping trips planned in a few weeks and I need the truck to work! Lol

[@Zaay93]

@@cjhancock4290what did you end up finding out on this? My truck just did the same and I’m hoping I don’t have a cracked piston.

[@cjhancock4290]

@@Zaay93 sure did, one of the injector hold down bolts broke, hydrolocked the motor, from what the shop stated, the previous guy that replaced an injector tightened it too tight and it broke, it destroyed the head, I ended up with a new heads, injectors etc luckily, the pistons were good, still a shit deal.

[@Zaay93]

@@cjhancock4290 damn, that sucks. Glad you got it fixed and I appreciate the reply!

[@TheChucks82]

So I have a question. Im replacing my main engine wire harness do I have to remove the a/c compressor or can I just unbolt it and move to get to the last plunge connector.

[@AutomedicGarage]

You don’t have to even unbolt it. The crank sensor wiring can be worked out from behind the compressor, it isn’t fun but it can be done. However unbolting the compressing would make it easier, just unbolt it and leave the ac lines connected you’ll have wiggle room.

[@packingbone1953]

Man, if I knew I had a mechanic like you relatively close I would probably pick up a 6.0.

[@AutomedicGarage]

Thanks for the compliment.

[@robadams-jz8mo]

I thought those were odd cylinders on that side

[@AutomedicGarage]

Passenger is odd driver even

[@urchinlookinmf]

My truck bogged down on me this weekend. It was acting like it wasn’t getting enough fuel pressure and my FICM voltage dropped to 35. If I replaced fuel pump and ficm would it fix it?

[@AutomedicGarage]

If FICM is only 35volts on the main that’s your problem. Replace and then see what it does

[@urchinlookinmf]

@@AutomedicGarage it will run good for about 20 mins and the voltage will be fine then it will drop suddenly and run rough

[@AutomedicGarage]

@@urchinlookinmf once you get below 45 it gets a mind of its own
