Got a call today from one of the branches of the company I work for and they sent one of our trucks from their location to ours because they 'blewed up the motor'. It's a 2008 F550 regular cab 2x4 with a 9' flatbed. Delivery truck used to pull a tandem dual gooseneck most of the time. It showed up around 5 o'clock this evening at our location on the trailer it normally pulled being towed by a Chevrolet dually gasser...
Anyways, I found out about the situation and confronted our fleet manager about it. He shrugged it off and said, "Already ordered a replacement. Gonna give it up at the dealer for $5k I guess."
I asked to take over this truck as my personal project. He's a Chevy guy, all our new ones are Chevs. My company truck is a Chev. But I'm not giving up on this old abused Ford.
I don't know hardly anything about 6.4's like I do about 6.0's, so this is where I'm asking for help. I'm assuming they are similar in the fact that any minute thing could make one not run. The 'blowed up' description given by the delivery driver is a little far from true.
Truck arrived right at dark and I had a short time to inspect it, but haven't driven it or even looked under the hood. Driver says its got around 200k miles. It's been deleted at some point, and I don't know how. There's no programmer, and I don't know how the DPF system is deactivated. It's got a delete pipe though and no pod on the dash. I have no idea who did this or when, but the DPF is not present.
Here's the baffling part. The exterior of the truck is covered in oil. Fenders, doors, tires, bed. All but the top of the hood. BUT IT RUNS.
I figured we were gonna have to push it off the trailer, being 'blowed up' and all. But the driver jumped in it, and it fired right off. No hesitation, no long crank, no rolling start. Busted off like every other 6.4 I've been around. Sounded completely normal. No fluids leaking. Grayish/white smoke coming from the exhaust. Not heavily, but puffing out at idle. No knocking, ticking, popping, etc. when he put it in reverse to back it off, then it developed a miss like a bad injector. It loped until he parked it and put it back in park, then it sounded normal again besides the smoke.
By this time, it was dark, and I didn't want to look it over or pull the dipstick without being able to see what I'm looking at. The truck traveled on the trailer for about an hour and a half, and there was no oil residue on the wood floor. I'm stumped to find out where all the oil came from on the sides. Obviously there was a catastrophic leak recently, that may or may not have been repaired. Not sure on that yet. So there's question 1:
What could leak on the top side of a 6.4 to blow oil out of the fenders in such a way? More or less, has anyone else had a similar leak or is there a weak point that may have caused that?
What's the next best thing to check? I didn't see if there was a CEL on. I'm sure there is. Pull codes and see from there? I hate to think that the engine is completely pooched just from hearing it start and run for that short time. It's the general feeling that the branch that had it just wanted a new truck so they've come up with this nonsense story about needing a $15,000 repair to get it back on the road. And I'm not one to let our company take it in the shorts by sending this truck to salvage for $5,000. It's still in decent enough shape to keep around, and it's a heavy hauler.
I'm hoping perhaps our location just picked up an easy fix and we can add another truck to our fleet (even though we don't really need it). Their loss in my opinion, they're replacing it with another Chevy gasser.
Like I said, I'm not versed on the 6.4's, and I'm asking for opinions on what to check for to see if in fact we've got a catastrophic failure or an oil leak and a bad injector or two. Thanks for reading--
