Archived need a new 5.9

[JerryNelson]

i need a new or reman motor. I'm looking for just a stock 5.9 motor. my number 6 cylinder is scored. where should I look for one.

 

[DavidC]

you can't sleeve it ?

Dave

 

[JerryNelson]

Dave wouldn't it cost more to sleeve it. versus a long or short block ?

 

[DavidC]

I really do not know but I would think it would be cheaper. 1 new piston and rings if needed along with sleeve and maybe machining. Maybe some guys that know the procedure will chime in.

Labor for r+r is the same. Reman cost should be lower than a long block. Down time will tell the tale.

Our engines don't have sleeves like the big rigs. Engine would have to come out, cylinders bored, and oversize pistons installed.

Cummins offers a repair sleeve. I think it uses a standard piston.

Would you still have to disassemble motor, do machining for sleeve then finish sleeve for piston ?. I would assume yes, but we all know about assumptions.

Dave

 

[mwilson]

Yes you would, but you know what you've got when it's finished. A short or long block could have the sleeves as well and possibly a ground crank.

The best option was the new block but that is no longer available. Shad and I checked that out a while back.

Never said they didn't, but I was thinking DavidC is talking about the big-rig engines where replacing the sleeve/liner is standard procedure when doing an in-frame rebuild with no machining necessary. Installing a sleeve in our engines requires a lot more machining than just boring a cylinder.

Geez, give me a little credit. I don't own a Ford, I know our engines are not factory sleeved.

I brought up the Cummins sleeve because it uses a standard piston. Nothing wrong with oversize but if my naked block was laying on the floor with a boogered hole I would go with the repair sleeve.

The machine work might cost a bit more but it can't be too bad as Ryder uses a similar Cat repair sleeve when repairing boogered C7 engines. If it didn't provide good results Ryder would not do it.

[DavidC]

Totally agree Mike. I would sleeve also if I was having his issue. At least I know what I have. Still not sure which way is cheaper as that may be the go no go for the original post.

[mwilson]

Must be tired, I used the term "boogered" twice.......wow...

Agreeded! WTF Happened?

 

[mweiman]

Unless you are really lucky finding used, I am going to say fixing what you have will be cheaper. Especially if that is your only damage.

If you have the time and expertise, or a trustworthy mechanic, I would repair # 6, whether that means a sleeve ( Cummins p/n 3904166 ) or a bore job, and do the rings in the other 5 holes as well. How many miles on it? How are the bearings? If you desire now would be the time to do any other mods, camshaft anyone ? Maybe I should ask - are you allowed to do mods where you live? I can do what ever I like up here and no one would ask or care or be able to tell for that matter.

When I bought my 03 # 6 was dead also but the other 5 needed a bore job as well. I chose to replace the block and do a custom build. It was built with towing and long life in mind. I'm happy with the results. Number 6 takes the most heat. There are even cooling mods that can be done.

Depending on your budget another option is a Cummins rebuild long block. I considered one when I rebuilt my engine, but I wanted something other than a stock injector pump and stock cam. A 12 valve was about $8k IIRC, so I expect a CR would be more.

 

[JerryNelson]

I had #6 injector stick open. I'm not sure what happen broken compression ring.and scored the cylinder. getting a lot of crank case presser. the mechanic told me i have a big air compressor now. time and money is a big thing. I have a 5.9 long block coming next week from blacks diesel performance. so i should be back on the road in a few weeks.
