Engine Cylinder sleeve

Post by fly4ad »

Has anyone tried or have any experience sleeving the cylinders on the 4AD? I have a lead on an engine block that has major corrosion in #3 cylinder. The corrosion is very deep, looks like half way through the cylinder wall. :shock: Is this salvageable?

A good machine shop should be able to do this. The sleeve should have a top ridge so the sleeve cannot move up or down. Probably would not move up because of the cylinder head but a friend had a sleeve with out a ridge slip down enough to have the top ring pop out and stop the motor. Lucky it was just idleing.

Sleeved my cylinders 2 years ago with no problems (about 3000 miles ago).

Thanks for the feedback!

I’m located in the Atlanta GA area. I located a complete engine that has a visually sound block, except for that one cylinder locked-up and down-right ugly with corrosion. Not being familiar with engine sleeves, it appeared to me that it was too far gone. After further ongoing education, I’ve come to the conclusion that it probably can be sleeved with no problem. My block has an ugly weld repair on the distributor side which I planned to repair with a plate and some aviation quality sealer, which would require no fasteners. I think it will work just fine with little cosmetic impact. My first choice however would be to replace the block. On the other hand, my dilemma is taking the original running engine, that will require an easy, low cost repair, and start from scratch and build another engine at a cost of who knows how much. This car has all the original major components that it came from the factory with, and it would be nice to keep it that way.

Mike, what do you think a stamp would cost to mail a block to GA?

By the way, I’m having a blast restoring this car!!! The frame is out to be blasted and powder coated. I’m in the process of going through the rear end and front suspension, in preparation for when I get the frame back.

Thanks again for all the help!

No idea on the shipping, that is why 3 blocks have already gone to the dump along with a few gearboxes and body parts, no one wants to pay shipping. Its a HEAVY block and not in great shape but externally appears to be uncracked but shipping will be a lot.

Sleeving is probably your best bet.

Fred,

have you been in contact with Mike Barber? He is also located in Atlanta, GA area and has quite a pile of Singer Roadster parts. I don't he treads this forum but I should have his contact information somewhere so give me a message if you need that.

Regards,
Pekka

I think you're referring Paul Barber in Cedartown GA. He has 3 semi-complete cars in need of restoration, and remnants of many more. I think he wants to keep the complete cars together, and is willing to sell them. One of them is a twin carb model. He has a host of other parts, but I've had only moderate success with the specific parts that I have needed. Paul is the first person I contacted when looking for a block, but the only ones he has left are in the complete cars and he's not willing to part out yet another car!

Thanks for help!!!

Hi Fred,

Yes, the one in Cedartown, GA. OK, it makes sense that he wants to keep the somewhat comple cars as they are and not sell the engines out of them.
