Hydrolocked 7.3
Okay. Some of you may have followed my other thread about my truck being a POS - the short version is that I was having issues and replaced the IDM, injectors, injector wiring harnesses, and after it was still having issues I found one copper injector ring missing. I replaced it and my truck ran fine.
Fastforward 1.5 months and 3,000 miles:
My truck started smoking a little bit of white smoke. I parked it at work for about an hour and went out and started it up - it sounded labored starting but when it fired up it started knocking like crazy. It sounded like a sledgehammer hitting an anvil. It put out such a large cloud of smoke I was concerned the fire department would show up. I quickly turned it off. A few hours later I went to start it again and it just hydrolocked after about 1/4 of a turn.
I read a thread here: https://www.ford-trucks.com/forums/9...hydrolock.html about another member with a hydrolocked engine and I've gotta admit I'm scared crapless. I hope like heck I didn't bend any rods. Here's the question. . . what to do now? I'm thoroughly depressed about the whole thing and have put enough money into it that I could actually have boughten a new (used) one.

Get it home, pull the glow plugs, and have someone turn the crank with a breaker bar by hand while you watch the holes to see which one shoots out fuel. Might be easier to just pull one side at first so you can keep an eye on it. If he can't turn the crank, pull the other side.
Where did you get your "new" injectors?

I got them from Diesel Care and Performance out of Memphis TN. I just barely google'd them and it looks like the BBB gives them an F. Also looks like other members here have had problems with their stuff. . . so FML is all I can say.

Yes. I had a shop do it the first round and they messed it up so I pulled it apart and redid them myself.

Diesel Care has been selling since Oct 04 on E-Bay and has 7,770 feed backs and have a 98.9% positive, kind of odd with just 5 problems reported to the BBB in 3 years gets an F score

Was just trying to clear up some misconception, in the past they have had some bad rap.

Okay guys. I ran a buzz test and injector 5 failed. Keep in mind these are brand spanking new rebuilt injectors. This is the second "new" injector I've had fail.
Cylinder 5 and 7 were both hydrolocked. I pulled injector 5 and the lower ring was shredded and obviously leaking. My ex-Ford Tech friend thinks my injectors were lose which caused compression to burn away the ring but I'm positive they were tightened to 35 ft lbs of torque. It is possible that the top bolt was lose. How tight is the top bolt supposed to be?

Update: threw in two new injectors, hand turned the engine over before replacing the glow plugs. After replacing the glow plugs hand turned it again just to be sure there was no fuel in the cylinders. I cranked it over with the starter and after about four revolutions it hydrolocked again. I pulled all four passenger glow plugs again and tried to hand crank it and it wouldn't budge. Looks like I've gotta rip into the drivers side. That will have to be another day because it's 3 am and I'm tired.

Regardless of what the BBB says or their biz practices, if Diesel Care injectors just caused this guy's engine to self-destruct, I'm pretty sure I wouldn't be recommending them......
I know you can't go wrong with Casserly/Full-Force stix.
