743B restoration help

I have not drained the oil yet. But I did pull glow plug #1 and it looked great. Now for more bad news, I pulled glow plug #2 and rusty water started pouring out. So I'm thinking it's time to pull the head and see what kind of damage is in the cylinders. With the starter being stuck I thought I was home free. Oh well, On to the next mission. I will start taking pictures to make it more interesting. Going to the Doctor tomorrow but gonna try some wrenching tonight. lol

Drain it pb it and have the doc cort you wish you luck on both Ant

Got the head off last night. 3 of the 4 cylinders had water in them. The head and valve train looks rusted solid. The cylinder wall on #4 looks to rusty to save. Oh well, Time to shop for a new motor. Where is the best place to look for a V1702 replacement?

I drained the oil today and about 3 quarts of antifreeze came out first. I don't see any cracks in the head and the head gasket don't look like it leaked anywhere. Is it possible for the sleeve to crack? The motor is still stuck and won't turn either way. also 2 of the sleeves look like they doped down about 1mm each. I guess I need to pull the pan next.

That engine is 36 hp the 2203 is 51 hp the 1702 heads are known to crack easy and you will have alot more in it than the $1500.00 that you can get the other for

I'm real sure that I'm going to put a new motor in it. Can you tell me where you see them for $1500? I'm tearing this one down to see why it wont turn. Its got me wondering how all that Antifreez got in the oil pan. Just something to do while shopping for a new motor.

Do I have to stick with a 1702 or can I swap to a more powerful engine. I don't want to have to buy a bunch of parts to get a different motor to work.

FYI, the Craigslist link shows the place selling the engines is near (southeast of) Kansas City with a eastern Kansas area code on their phone but apparently they will ship to St. Louis.

Thanks ant, I found this about the swap. I really don't want to have to modify anything. The major difference between a 1702-2203 is the rear main seal.To fit the rear mounting plate off a 1702 you will have to weld up and re-drill bolt holes around rear main seal housing.(2203 holes are a larger pitch dia.)The hole in the plate will also have to be machined to a bigger dia. as the rear main housing is a bigger dia on a 2203.Sumps and manifolds swap over.

I did not know that I thought you just changed the manifolds oil pan and rear houseing off the back and maby a new hole for the dip stick but the place I sent him claims to know all and might be able to do all the swapping for him and give him something for his old engine not that far away make a nice day trip if he could set it up
