Well I pulled the engine out of the Courier. I was going to fix the rear main leak, and have the heads redone. It was a very good running engine just leaked a lot of oil. So I get the heads pulled and find the drivers side rear cylinder has a crack about half way around the cylinder. I know we could have it sleeved but now is not the best time for me to do a complete rebuild.

Iam thinking about just replacing the rear main and running it till she goes, but that could ruin a lot of other parts that are still usable. I wish now I had not promised the wife she would be driving her wagon when spring gets here. Anyone one want to volenteer to tell her for me?

If your gonna run it as is, clean the crack up a bit and jam some JB Weld in it, fixed a Vega Block with it when I was a kid, it held.

A buddy of mine was changing head gaskets on a mini van. got a little carried away cleaning the surface of the block with scotbrite sander and gouged the block. He put it back together and it leaked water. took it back apart, a little JB Weld and carefully filled back smooth.  Reassemble and no problems.  Not saying I would do it, but if you really need it running.....

On cracks, if you can, take a drill with the smallest bit you have and drill a small hole on the end of each crack so it won't go any further. Then JB weld it and it should hold. I always heat up the area around the crack with a torch first before appling the JB so it sets into crack better. Thats how I was shown to fix it and always worked for me.

Thanks for the replies, I agree with the thought of drilling the ends of a crack to stop it. But this crack is in the cylinder wall about half way down.  even if we could JB weld it that would play heck with the rings.

Use a right angle drill adapter to get in the hole. After heat/JB weld you could run a cylinder hone through it. Should take car of the ring problem unless the crack has a lip on it. Chuck in NH

You've got an oil leak problem & a cracked cylinder and the engine is already out. So, If the engine is alright other wise, maybe you should spring for a sleeve job. Then clean it up well & re assemble it. Just a thought...

If its a 272, those blocks can usually be bought at scrap iron price. You might consider starting with a fresh block.

Do yourself a favor and don't go any further. Any time or money spent is wasted. You need to go with another block or sleeve it. Fixing it is the only answer.

This is true!  and you'll be a lot happier in the long run.  You have the engine out already, don't 'rig it, do it right.
