You can get a short block (and other parts) from these guys in Houston:

Short Block Perkins A4-236, Perkins Short Block A4-236

There are a number of short blocks, and complete engines (both new, used, and overhauled) on Ebay.

Thanks for the reply, I guess these are aftermarket engines, any experience with them?

Fortunately, no I don't have any experience with them. When I saw looking for manuals, and a few parts for my 241 I stumbled onto a few sites like that one, and also saw an article that a company in England (think it's Vapormatic, or similar) started making new short blocks for some of the more popular Perkins engines. Your engine is used in so many machines (including large sailboats) that the demand must be there.

Are you just going to put another motor in it? Why not rebuild the one you have and do an inframe on it?

I have not rebuilt a motor in about 20yrs, is it an easy motor to rebuild and can I do an inframe? thanks How do I determine weather or not I can do an in frame? Thanks Massey Wrench

I never read a reply from you from your other post about your motor that is now on page 2 of this forum. Did you ever find someone to help you get a compression test done. Honestly that is what you need to do first. I have seen that same motor do the same thing your motor is doing because it got water in it and seized the rings.
Or you could just tear into it, lightly hone the cylinders with a round ball hone to knock the surface rust off of it, re-ring it, new rod bearings since they will be out, top end gasket set and put it back together and I would almost bet it stops. With that low of hours on the motor, I dont think its shot and/or requires another motor.
A compression test would isolate the cylinder or cylinders that are causing this problem. I have replaced one piston and one set of rings before on this type of motor teardown to save someone money because the motor had a very low compression on one cyl and the other 3 were factory spec because of this same problem. This may not be as bad as you think.

If you have a couple of good jacks, couple of jack stands, a cherry picker (engine hoist), and a good flat hard surface (preferably a shop to protect the inside of the block from the elements when its apart), you could easily do this if you have rebuilt a motor before. But first you really need to check a few things over.

Here is a picture of a motor that had water in a couple of cylinders. Just this slight amount of surface rust is all that was evident but the rings were stuck and had a massive amount of blow by coming out the tube and blowing it out of the dipstick.

If I still lived in Santa Fe I'd lend you my compression tester, but many auto shops will rent one to you cheap.

Don't I have to have some kind of special adapter?

The kit comes with them....pressure gauge with flexible hose, and several adapters to go in different size spark plug holes or injector holes. I think I paid $30-40 for my kit, but renting them is probably $10 or so.
