DieselD Posted November 6, 2007 Share Posted November 6, 2007 04 F350 6.0 with 123kmiles. concern is engine started missing and running rough then stalled and would not restart. when I get it it will not crank, engine is hydrolocked. Has contribution codes for cylinder 4 and 8. looking under the truck there is a puddle of fuel coming from the left exhuast manifold. Suspect injector stuck open and its hydrolocked from fuel. remove the vavle cover and injector 8 is jacked. the screen on the injector for the fuel inlet is gone. I assume this is the cause. I check torque on the rest of the bank and find #4 to be loose, or so I think. I sell 2 injectors. Replace 8 and move on to 4. I loosed the hold down, no remember the bolt was loose. As I am loosing the bolt gets harder to turn like when its poping the injector out except it not right. I stop and look further. the hold down is not coming up like it should but the bolt is. Ok so the hold down clip is screwed. figure I grab a small pry bar and ever so gently pop the injector out. little by little I step up pry bars and force used. I am not beating on this thing and cannot get it out of the hole. I have a feeling this gravey customer pay job just turned into a steaming pile of poo. so what the hell is going on? why in the world would this thing be stuck so hard in the hole it will not come out? I fear engine damage??? Quote Link to comment Share on other sites More sharing options...
DamageINC Posted November 6, 2007 Share Posted November 6, 2007 I wish I knew what was wrong, but I wouldn't be surprised if you end up saying "off with it's head" by the end of the day. Dave Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted November 6, 2007 Share Posted November 6, 2007 I had a 7.3l do the same thing. The o rings bit into the cup. I ended up bringing the whole cup out with the injector using the prybar method. Not sure if this is viable on a 6.0l though. Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted November 6, 2007 Share Posted November 6, 2007 I have seen mushroomed injector tips and major engine failures that can cause this concern. Good luck. /forums/images/%%GRAEMLIN_URL%%/drinkingdude.gif Quote Link to comment Share on other sites More sharing options...

Dave yup that was my fear. When posting I really already had my own answer but wanted to see if there was any other lucky souls that have run into this. Shortly after my post I pulled the glow plug only to find it smashed to peices. Something has come apart and done some serious damage. No sense is pulling the head really since I already know its going to need an engine. Its customer pay so Im going to have to sell it. I will probably pull the head once its out just since Im curious as what the deal was. I have a feeling this thing was driven as it was overfueling and caused the failure.
