Kevin Rutherfrauds $200000 Signature glider truck has complete engine failure!!!

So maybe they should have bought an MRAP, LOL!

 

Well really, why would you at this point want to salvage that block? I mean there's so much invested now at this point you would think they'd just start anew for this guy. With this engine chances are something will go wrong again and they'll all be pointing fingers at whose decision it was to keep the old block.

 

Actually, on any engine build, I'd prefer (and many builders agree) to have a pre-used block over a virgin new block, as all of the thermal shifting/distortion has already taken place and it produces a more 'stable' block. Any previous overheating issues with the KR signature truck's block would mainly affect the liners.
For sure the liners are waste-bin material now.
The majority of the block would only see temps of less than 300* for sure, so not hot enough to damage the block itself.
If the sleeve counter-bores are concentric, and the deck is flat, then all should be ok. Just need to fit new liners.

 

That is why many are calling KR Rutherfraud. He got a couple who clearly show their inexperience by doing things that turn around and cost more than they save. If you are power only, don't expect that you will be setting records in mileage. Their truck is HEAVY, and all the sycophants are justifying it as they have securement equipment. If they are hauling dry vans, they don't need 2,000 lbs of chains. If they don't have that much in chains, the truck is not maximizing its weight.

 

I guess I should have stated that they should just put another reman in from Detroit, leave as is and send the guy on his way.

 

...and have them admit defeat? I don't think they want to do that.

 

That's the problem, their egos won't let this poor b..d just git on down the road.

 

Scored liners indicate an overheating condition. However, the engine was rendered inoperative, and therefore disassembled, after multiple intake valves failed a leak down test.
From pitting on the Pistons, it would appear as if dirt entered the engine, causing the intake valves to fail.
Even though there was heat damage, the engine continued to operate without any severe drivability problems.

 

Think about what you have. An engine with advanced timing, a small turbo building tons of boost down low, and running for extended periods near torque peak. All of which mean high combustion pressures. Add in liners coated with scale and the increased liner temps that brings, and it's quite possible there's liner distortion that occurred. Yeah, the piston is normally first to go, but at least it still had the oil jets for cooling; those scale-coated liners might as well have had a air gap to the coolant.

I guess it's hard to imagine that anyone could screw up so bad that they couldn't even cut the counterbores perpendicular to the cylinder axis. You know there's no way Detroit shipped a reman that way, and as much as I think Bruce is an idiot, there's no reason they should have messed with the counter bores. I suppose it's possible they didn't make sure to get the right jug in the right hole, and never actually checked protrusion, but that still doesn't explain the crooked jugs.

 

What makes me feel there were errors in the machinework/fitting is the liner that was .001 below deck (and flush w/ deck on opposite side), plus the liners with minimal protrusion (.0005 or less). Now if the liners were found at greater protrusion (say, +.003 range) coupled with being non-perpendicular, then I would feel that is more likely to be solely 'over'-heat induced. In my view, heat distortion would likely ADD to measurements, and less likely to have them decrease, for this given interface.

This is all 'back-seat' analyzing because we don't have the benefit of even the quick process of measuring the counterbore, deck flatness, or sleeves. Nor do we know the duration or degree of the actual elevated temps. Heck, don't even know what egt's they were running.

The scale/corrosion is probably the biggest mystery, in that, can we really be sure the interior block and outside of the wet sleeves was 'as corroded' as the head?
There was one pic of the block's deck, and I didn't see but slight signs of corrosion in the water passage holes. No where near the extent of corrosion the head displayed. But then again, could only see the small water passage port, and hardly a good 'interior sample' to judge actual inner scale/corrosion.

I'd love to be able to see a view of the sleeves pulled, with a good look at the block's interior, and especially the sleeve's 'wet-side' walls.
