Tearing Down a JUNK Engine From One of Our COMPETITORS!

In todays episode we are tearing down and inspecting a customer's failed engine to see if it can be a viable core. Turns out that the engine that failed is actually one of our competitors! Come along with us as we investigate the reason this 6.7L Powerstroke went down.

To explain what a core charge is, I would say the price of a rebuilt (engine for example) is reduced by the assumption of getting the old one back in rebuildable condition.

If what is returned is not rebuildable, there is no value in it and results in a higher price to be charged for the rebuilt one.

You should send those blocks to India, some dude in sandles squatting on the floor of a shop will weld a bead around those main journals, then machine it back down to size, probably for 2000 rupees.

Hi, I'm a engine builder in England i noticed on a previous video that you have issues with core plugs we now clean clean clean then fit with pipe seal from wurth pressurise the engine to push the sealant into any pin holes then leave it 24 hours with no pressure and it will cure your issues and a coating of pipe seal inside will prevent any damage from water. Never had a leak from the plugs anymore. Hope this helps

Around 15 or 20 years ago, I installed an electric preluber on my 6.9 L Ford diesel. It was just wonderful, it would turn on for a few seconds when you turn the key to accessory, and it would also run for 30 or 40 seconds when you turn the engine off. I was very pleased with it.

I love how he shows the Jasper sticker at 9:28 as it’s going into the trash!

[redluck]

My father always told me that if it spun a bearing, find another motor. He never told me why. Thank you for the explanation.

[russellhochmuth]

Line bore..have 3 trucks with it done. 200k+ on each engine currently. If you know what you’re doing, it can be done and be perfectly fine.

[barrygunning]

I can't tell you how much I've learned from this channel over the past years or so. Great stuff as usual!

[chrishughart]

It’s kind of funny you say this. I bought a 12 Yukon with the 6.2l in it and when I bought it they had installed a remand jasper engine in it and about 20k miles later the oil pressure started to do weird things and the engine started to make knocking sounds. They sent me a new engine and I haven’t had issues since. But I worried about their workmanship after the first engine failed.

[harrymorrice]

Could use an electric pump to prime the oil system before every start. You could even time it with the glow plug light so when that goes out the oil has primed and the engine is ready to start

[mikehachenberg]

I like your channel, you give me a lot of information, that I not aware of. Great channel

[darrensteuber]

I was told by a Ford diesel tech that Ford says that using a heavier weight oil than Ford specifies will cause spun bearings because the 6.7 has tighter tolerances than previous engines.

[janet]

On large ship engines, they pressurize the oil galleries prior to engine start.

[AncientAir]

Can’t line bore that and oversize main bearings? Also, In another video you asked the viewers to guess the “fix” for thesis very issue. I believe your fix is custom main caps and girdle, with ported oil passages from the upper pan immediately after the pump straight to the custom main caps with Al equal length lines/passages so all caps get oil at the exact same time. When the patent comes out I’m sure I’ll see the post… but if you read this, hmu if I’m near correct with a response 🤙 totally dig watching you and and your team work… absolute craftsman!

[forrestmanueljr]

I thought you said in past videos that you could repair the block with a line bore and oversized bearing?

[brucejones]

I spun number 4 main bearing in my 2000 Cat C 12, when it had just over a million miles on it. Had the engine line bored by Love here in Salt Lake. Had to replace the crank ($850). The engine died with over 2, 177, 000 miles on it when a cam follower bearing failed and the roller fell down slong side the cam which punched it out the side of the block. So, yeah, blocks can be line bored to save the block ....IF.... it hasn't been damaged to much.

[dougnorton]

Strange, I maintain several 6.7's from a fleet of works trucks and none have had an oil related failure yet. One truck was recently totaled with over 225, 000 miles and I just completed service on another with close to 160, 000 miles and no issues. There have been a few others sold from the fleet with high mileage and no oil related problems, though two were let go for sparkles in the fuel. I think there is something else causing these failures. I ALWAYS fill my MOTORCRAFT oil filters on a 6.7 and I use Rotella T-6 5W40. So maybe it's been luck, but I think it's abuse that is causing these failures.

[johnconnor]

Dave, first time reading comments under your video. Glad you have thick skin! Keep going, you’re doing great!

[scoobydbed]

It couldn't be align honed back for bigger bearings? Just very interesting the block is done from a bearing, was it just so damaged that it isn't fixable or is that not something you usually do in this situation.

[brentmcmahon]

I know 2 guys who put preoilers on their 7.4 and have hade great luck with it. When the hit the start button the preluber will run until the gauge shows 20 psi then the motor cranks and with about 275k and no issues so far .
