Damaged block installing block heater L5240

[truckdiagnostics]

I am going to disassemble and bring them the bare block. Before I tear it down any further though, I am going to bring it to them the way it is to get their opinion. If they say yes, we can repair it, then I will give them a deposit to order the liner. I will continue to break it down and return to them for the work.

If they can't repair, then I will bring it home and park it in the garage while I search for a replacement. Depending on cost, either a reman or new. I have requested quotes from a few places already. One a few weeks ago ($6200 for a reman including shipping), and another just this morning. My block is worth nothing as a core, so I might as well keep it for the $200 or so they might give me for the crank assembly.

She will be running by the end of April, one way or another. This is just a bump in the road.

Sounds like you have it figured out. When you pull it apart this is where you need to mark everything! I have a set set of letter and number stamps for the bearing caps and rods. You can if your careful pull it a part and reuse everything. The only question I would have and some else here maybe able to chime in would be leaving in or replacing the cam bearings. Some cleaning methods can pit the cam bearing. Then if you put new in running with the old cam?

If i missed it sorry , but if that block is not repairable can you not just buy a new bare block? I would think it has to be cheaper than a complete remain ? If you do fix that block i would defiantly have new cam bearings installed, wont be a issue running the original cam.

Yes. A new block is around $3200.00.

your going to want to have the machine shop install the new cam bearings, I can go either way on having them install, the freeze plugs...

I would think if you sleeve it you still have to repair the hole to keep coolant from seeping.

AND one block heater in place of a freeze plug,

I think you are correct

He said several posts back that they were going to weld up the holes, then machine the block and install the sleeve.

Appointment made with the machine shop for inspection tomorrow night. Fingers crossed.. I have to take it back off the engine stand tonight and strap her down real good in the back of the truck.

I hadn't seen post #211 showing the holes above the piston. I'm usually an optimist about mechanical repairs but this time I really question whether it's worthwhile. With the thin walls there's too much risk. The longevity of the repair will always nag this engine. It's a tough pill, but replacing the block will restore your confidence in the full service life and lasting value of this quite young L5240.

Mig weld the holes, Bore close on any old Bridgeport mill then finish hone that cylinder......DONE!

I've bored old Volvo engines on my mill with great success. These were clunkers with many miles on them.

Practice mig welding on some old brake discs then have at it.

Look at them laughing at the Fred
