A little off topic Anthony but I thought you were an over the road driver with your 6.0? I see you may have converted?

 

We can still head out,, but the shop has been busy enough that we can stay home. I need to be able to explain how my 06 has 808k too. Customers absolutely love it. Also the fact that I bought it with 85k on it. I'm not driving something that someone else has worked to get the miles racked up.

Here's another vid

 

The deck of the block looks like they hit it with an abrasive disc on a die grinder. I would not be happy if that was mine from Ford.

 

It actually looks like it was hit with an orbital DA!

So what year is the block? Did you use a bore mic and see what the bores measures?

it looks like they did just the bare minimum on the machine work.

Either that or it was a Monday or Friday rebuild!

 

Would be interesting to use one of these on it.
SR400 Surface Roughness Tester

But that would really be a lot of $$ and a lot of OVER KILL.

How did it test out for being with in tolerance of any deck warpage?

I would be a little concerned that the cyls were not crosshatch honed and the rings may not seat properly

 

Can you guys guess what I would do if I had to pay for this block?? Do you remember what happened last time I got a subpar engine?? I'm a picky sob. And I just got my "spot check" on Ford,,, finally. I wonder if it'd be different if they knew it was going to a shop that will air the laundry on the product.

I've got a fresh machined block that I'm going to put side by side and have my dealer rep see what a properly machined block should look like. Then let him see what his looks like. It's night n day.

 

Not just that they won't seat,, they will trash the block.

 

With the newer technology of ring material and such I see in other products, they may not need some of the same features we saw years ago. It would be worth asking to confirm that. Also if the cylinders have a coating on the walls, crosshatch honing may not be required anymore and in the cases of better cylinder wall coatings, honing may actually kill the cylinders.

Wouldn't hurt to ask someone that knows the manufacturing they are using, we all know how fast the industry moves and innovations never announced.

 

Does this rep know what he/she will be looking at and what/why it should be
the way is needs to be? In other words is this person a mechanic or a desk jockey.
We all know how smart the desk jockeys can not be. They drink the Kool-aid and
spew it right back out at some person that most times does not have your knowledge


Nitriding could be the reason. But that is just a guess. I don't even know if they are doing
that to diesels. It's just that one show of the walls reminded me of what one of Lycoming
cylinder looks like. So maybe or maybe not. Most likely not.
But I can't wait to hear what ANthony finds out.

Anthony I would love to see the two blocks and heads side by side. Post up some pictures. .

 

Anthony, I'm curious if you don't mind. What do you charge for a rebuild compared to what it costs for a Ford reman? Just wondering what the cost is for quality. I think I'd be inclined to lean toward the quality/detail route, if within reasonable.

 

I do not know what you think is reasonable but it will cost you more if the quality is lacking.

I stopped by the shop last night and got to hang with Anthony and Julie and give a hand here and there with stuff on this block. Anthony's attention to detail is OCD. He spent almost 2 hours prepping the block surfaces for Heads. His shop helper (Phillip) was fixing his turbo and Anthony made him wire wheel the housings outside so nothing was floating in the air (it was raining off and on all evening). Anthony finally called it a night when the head gasket he was going to put on had cardboard debris embedded in it from not being shipped in a protective wrapper.

This takes time and does cost more for both the customer and the business, but it makes a big impact on the outcome. I would rather pay for this and do it one time than get a great deal on a crappy product and pay twice. There are places that you can take shortcuts, but as anyone who has looked through this site knows this is not one of them. You will do it again.

 

Possibly..............But do a little Google search for crosshatch cyl honing. I couldn't find any info on not doing it. It's pretty much a standard of the industry.

Hastings Mfg (remember Hasting piston rings?) even talks about the angle of the "hatching"

From: https://www.hastingsmfg.com/ServiceT...efinishing.htm
Here's an article from "Engine Professional"

It's a short PDF on cylinder refinishing. It's interesting to note that they all seem to talk about how to crosshatch hone or the angle at which crosshatch honing is optimum. none of them indicate that it's "ok" not to do it at all.

www.aera.org/ep/downloads/ep2/ep04-2008_10-18.pdf


If I saw a block where the cylinders didn't exhibit a honed finish (because the crosshatching was absent) I would conclude that the re-builder DIDN'T hone the cylinders after boring and before assembly.

Just because the short block is a "reman" doesn't mean every step was performed.


Just saying.
