Hey guys, bout a month ago I stupidly tried to cross the "shallow" spot at our local man made lake, which I had done probably a hundred times between my two pickups, never had a prob. Well the last time, it wasn't so shallow. I hydrolocked the motor. I have full coverage, insurance sent it to the local diesel specialist. He yanked the glowplugs, turned it over, to blow out the water, reinstalled new plugs, new harnesses, new starter. He then said he used his computer to boost my turbo to 80psi to blow out the intercooler, which sounded nuts to me, I could be wrong. Next thing I heard was I needed a new turbo. Hhmmmm. I okayed it. They said the truck was ready for me. When I went to pick it up, I watched them start it for me.....WITH NO OIL FILTER. They ran it ten to fifteen seconds before we saw the growing puddle under the truck. They put a filter on it. I drove it for a couple days brought it back because it was doing a funny surging thing, I could watch the tach bounce +/- 50 rpms and could here it in the exhaust note. I could see my boost was moving a little as well. I brought it back in, they kept it for two weeks then spent half hour putting an EBP sensor on it and cleaning the tube. he also reflashed the pcm. drove it for two days, didn't fix it. Today I was driving on the highway going 55 and the dang thing just fell on its face, dropped to an idle and wouldn't idle up even if I stomped the pedal. But it idled GOOD. Weird. Surging, now this, some major turbo lag, constant smell of burning oil, blue smoke at takeoff sometimes....what am I and these idiots at the shop missing? He says drive it, it's normal, it's obviously not...any ideas? Thanks guys

 

This can't be going to end well.....sorry I can't help you but I will sure be paying attention to those who answer your call for help. Doing EVERYTHING right can still not be enough for the 6.0 or so I have read and dunking it to the point of hydrolock just has to be a sin punishable by death, (of the engine that is).

 

Oh, and I didn't mean to add to your anxiety, I'm sure you already have plenty of that. Being a new 6.0 owner myself (and doing my indepth research AFTER I pulled the trigger) I am hoping for a favorable turn out for you. You have certainly came to the right place to get the answers you are looking for and Good luck with your issue. Mcrafty1

 

I appreciate that, Crafty....I think the initial splash is what got it, I didn't even get the carpet wet.....and it's stock height! I don't think it takes much on our trucks to hydrolocked them....very little room between the valves and pistons. The motor still sounds VERY healthy, and the truck runs good... just plagued with a bunch of little stuff now, I think a lot of the problems are caused by the shop I have it at, not impressed! But it'll get there, that's what insurance is for! Or they'll buy it out. I'm just not happy with the way it went to an idle today at 55mph, it acted like it wasn't recognizing pedal input. I actually was able to get it to run normally by unplugging the ICP

 

Either ICP or IPR, whichever is on the pass side valve cover. Would that sensor make the turbo lag sometimes and blow a little blue smoke, and a light surge on moderate acceleration? Or am I looking at a variety of problems? Right now there's no codes on the computer, the shop couldn't pull anything either. Right now it has new EBP sensor, cleaned tube, new turbo with old actuator solenoid( not impressed by that), new starter, Glowplugs and harnesses. Thanks guys

 

Sounds like maybe the water has done some funky stuff to the electrical system, maybe time will help cure the problem, I doubt that the oil filter issue will have hurt your engine because it should only be filtering a small percentage of the oil at any one time so the engine will still get plenty of lube as long as there is still oil getting to the pump. At least in any other engine I have ever owned that would be the case. But the 6.0 seems to be a different animal. I like mine so far 103,000 on the odometer when I bought it but it came with a clean carfax and an Oasis report from Ford showed it was serviced there it's entire life with very few issues( only one involving the engine, a vacuum line at 17,000) but........ Anyway I wish you luck and sorry for the rant, I didn't mean to hijack your thread or any thing, just venting.

 

Lol, no prob....I've owned my 6.0 since it had about 20k.....and it never even had a HICCUP til I did this a month ago at 89k miles, been a great truck. But I think I could've done a better job on the truck myself, but the insurance was covering it. It's just every time I bring the thing back in there the owner tells me it's normal, drive it. I've had my pickup for five years now.....and i know it AIN'T normal! LOL. I know my truck. I was just hoping one of these 6.0 guys would see this and say " I know EXACTLY what's wrong with your truck". wishful thinking. SIGH. It ISN'T going back to the shop, I'll fix it myself, at least I'll know it's done right.

 

And congrats on your new truck!

 

Thanks for the congrats. You undoubtly know your truck AND the 6.0 FAR better than I do so don't mind me, I have only had my truck a couple of months and I really like it and have found it to be a sound unit. The problem being about the only stories we hear about these are the BAD ones. I really don't worry much about mine I am just going to take the usually care if it that is advised....no custom tuning and I believe it will be fine. I'm sure yours will be too. I'll be following this thread and if I can add anything I will otherwise I won't be chiming in much and again, sorry for the negative comment at the beginning I was thinking out loud again.....lol. Mcrafty1

 

no prob, and I appreciate your input!

 

So was the oil just soaked all over the hood and top of the motor too?

 

No, just the entire undercarriage.... The turbo has a bad oil smell on shutdown though, and I also noticed under the truck oil appears to be dripping down the bell housing from the top somewhere. Truck didn't have ANY leaks before I dunked it. It's also very laggy and puffs blue smoke on take off every once in a while. now it surges and the motor went to idle at highway speeds. The only way I was able to get my pedal to work again was by unplugging the sensor on p/s valve cover...ICP I believe?

 

I did come up with two codes when I got home yesterday after my truck lost acceleration...p0237 and p2285, which may have been caused by me unplugging the ICP, but I can't be sure.

 

Do you have a cold air intake or other intake pick-up mod? I'm still trying to figure out how you got the water in the engine with a stock filter set up and where it draws air from....

 

No, stock intake...it looks like it draws air from right beside drivers headlight. I wasn't really that deep, I think the initial splash is what got it.
