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

I think it was a Vulva with an ISX.

 

I listened yesterday and KR said it was going to be built back mostly stock, that the truck needed to get out there and make some money, and then they will start on the modifications again. He seems very determined to prove to everyone how smart he is, be it at the expense of someone else.

 

In 2011 a guy from home drank the kool aid and decided he needed a PP overhaul on his CAT. Pulled the engine and hauled it out there in his pickup. They had it for 4 months. Then when he picked it up they could only tell him what the hp "should be" because they didn't have a dyno. Hauls it home, puts it in the truck and it wouldn't start. Turns out the ECM was fried. "We needed to use yours on another one and forgot to put a new one on". Yeah, forgot. Long story short, they about broke him and don't stand behind their work.

There also the guy I work with now that had to overhaul his 3406b twice in 6 months because PP sent aluminum pistons the first time. The second oh was also all on his dime.

 

I guess I'm thinking if old oil caused the bearing wear we would have seen more wear on the other bearings.

 

I will bet that scored rod bearing belongs to the rod that belongs to the piston that was in the cylinder with the scored liner .

Bet that cylinder got a little lean and hot on a hard low down pull and maybe a bit of detonation, maybe hammered that rod bearing a bit.

one way or another good thing they pulled it apart because a knocking rod was only a ways away.

 

Are we agreeing that the old oil is a red herring?

As Hammer166 mentioned, it Would be nice to see the journals and other bearings.

 

I could be wrong, but I believe the contamination was between the bearing and the rod. Which creates a high spot on the bearing surface. Which results in scoring at that point on the bearing. It to me is a separate issue from the corrosion. It has nothing to due with MB, or break in oil.

 

How many times was it back at PP, and they never insisted on changing the break in oil. Something doesn't smell right here.

 

No, the oil in an engine after a rebuild even in an immaculate shop will contain elevated levels of dirt that appears as silicon in oil analysis. That alone will polish the liners, and certainly isn't going to help the rings seat properly. There can be metal fragments as well that will damage the engine. This may not be the root cause of the bearing damage in this case, but it's not going to do the engine any good.

 

Agreed, I think one lesson learned is IF you are going with a bypass filter it may be wise to change oil at 5,000 miles, and then at 15,000 change again and install bypass filter.

I was serious about the bearings though, is that greyish stuff the micro-blueing ? I don't know what it looks like. Some guys claim it wears right off, is basically worthless after running the truck. I figure an engine apart with 100,000 miles should be able to prove or disprove that, even if it has other problems. At least if the surfaces are still coated or not.
