Damaged block installing block heater L5240

[Adiredneck]

We pulled some more logs out this morning until noon. Had some lunch and then started to mount the engine to the engine stand. Had to make 2 trips to get the correct length metric bolts.

I pulled the head tonight. I dunno. The holes are above the top of the piston at BDC. There is not a lot of metal between the cylinder and the water passages. I won't know for sure until I take it to the machine shop. Before I strip anything else, I might as well load it up and take a ride this coming week. My hopes are not high.

I agree. You should show the machinist what he's working with. Good Luck!!!!

Dang, hate you had this problem, but least you know for sure what happen and are able to handle the labor of removal and install yourself.

I also inspected the other cylinders. Cylinder 3 has a gouge in it. I can just barely feel it with my fingernail. Cylinder 2 has one, but it is less pronounced. Probably nothing a hone won't take care of.

You must have had a dang sharp drill bit. Not sure what they will say. Better down low where there is little compression pressure.

Similar situation but even lower:

even if you have to get a new head your still way ahead on expenses.

The block is the problem, head was ok unless I missed something,

if the shop is still up for it:

That's where I am right now. I was quoted $400 for the one cylinder to be welded, bored and sleeved to factory diameter from a shop 30 minutes from where I work.

I would still go for it- If it's a good shop they will tell you after looking at it whether it is ok for the previously quoted procedure. Here's hoping for the $ 400 fix

I am also wondering where in its stroke the piston was when the hole was drilled, you may still need to buy a new piston if it was drilled to.

Yes, head is fine. I planned on buying a new piston and rings for that cylinder anyways.

see #7 on the above link. I know most that have posted here seem to think a machine shop for fixing and assembling your engine is the next best thing since sliced bread. I do not happen to agree. They are in the business of machining so they are going to have a tendency to tell you a liner is going to work fine. Also, in the grand scheme of things, they are the ones with very little labor into the repair if they mess up. I prefer to have the machine shop do the machining, then I like doing the assembly. It is also looking like the OEM won't recommend the liner as a repair. Your doing fine. Based on what i have seen you should be able to assemble the block. You will end up having to buy our borrow some measuring equipment, but you will have them for a life time.

I just measured the distance between the damaged cylinder and the next cylinder. .318. Not as bad as I thought. The distance to the closest coolant passage: .211. So the bore on this engine is 3.40". Looking at some cylinder liners tonight, the OD is 3.59 on a 3/32" liner. So I am looking at .19 of difference. Deduct .003 for a press fit and I figure they will need to bore the cylinder to 3.587. That's a difference of .187. Divide by two, and there will be .0935" of metal to remove from the cylinder all the way around. Correct me if my math is fuzzy. This keeps me from thinking about the 6 grand I was quoted for a remanufactured engine.
