CRESTY flathead4rd 02-12-2012 @ 4:24 PM reply profile send p.m. New Member Posts: 169 Joined: Oct 2009 Most leaks come from head gaskets. Where is the water collecting? Front or rear of the engine, out the tail pipe, in the oil. More info needed. Did something happen that makes you think the block is cracked, like over heated or frozen? Let us know. cresty 02-14-2012 @ 4:08 PM reply profile send p.m. Member Posts: 32 Joined: Oct 2009 Thanks for answering!---I think it is from running it on too little anti-freeze!

If your temperature got below freezing for an extended period, it could have frozen. Otherwise, the water in the oil pan probably is from another cause. Most freeze cracks happen on the inside of the block just over the oil pan flange area.

It was on the right side in the flange where the oil pan mounts about half way between the front and rear. I ground out the crack and filled it with a little JB Weld. It worked until I restored the truck and replaced the engine.

Soon after the car was together he found water in the oil. Turns out that a pin hole (from rust) had developed in the lower part of a cylinder and was leaking water into the pan. In this case he was able to sleeve the motor and save it. supereal 02-15-2012 @ 8:04 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Some time ago, an engine was sent to our shop because it had spun a rod bearing due to contaminated oil. Upon disassembly, we found that an improperly sleeved cylinder had sprung a leak along the bottom. Due to the original scoring that had prompted the repair, we elected to not try to resleeve it. It didn't make the owner happy, but we couldn't guarantee the new sleeve would hold, either. Due to increasing scarcity, many flatheads receive repairs that are risky, often to allow a quick sale.

How cold did it get? If your antifreeze mixture was 30% it would have turned to slush at 10 degrees F. Colder temperatures and less antifreeze could cause the antifreeze solution to harden and expand. Water in the pan could also come from a blown head gasket. Before disassembling the engine, I would try a radiator pressure text and look for leaks. If no external leaks are detected, I would perform a cylinder leak down test. This will let you know if the leak is in the upper cylinder area and which head to remove to check for the leak. Most small cracks can be repaired by stitching the crack, but you should have the block magnafluxed to find cracks that are not readily visible. This will require complete dis-assembly of the engine.
