I recently purchased a '49 3/4T pickup. The thing runs good, but I started to detail the motor by first scrubbing the grime off of it and noticed what appears to be some dampness about half way up the block on the driver's side. It looks like someone tried "fixing" a crack in the block with some kind of weld or JB Weld-type product. Someone probably didn't winterize it is my guess. The leak is very small,nothing more than a drop on the garage floor the next morning, and it doesn't look like the oil is contaminated. What if anything can I or should I do?

Hi scottb, There is only one good solution. Replace the block. Other solutions: 1. Strip the block of all items that can be removed and take the block to a welder that has knowledge about welding blocks. 2. Remove the block and have it stick welded with cast iron rod. 3. Try to clean the block area while it is still in the vehicle. Trace the damaged area with a angle grinder. Fill with JB weld fast set. 4. Flush the cooling system and use cleaner. Add radiator stop leak. 5. Flush the cooling system and add "water glass". 6. Place a bucket under the leak and take no further action.

If you only have that small of leak, just be thankful you haven't taken it to a 'dobber' that thinks he is a welder, You will probably end up with a worse problem if you try to have it welded, Barrsleak or water glass or the J-B weld fast set usually works if the place is prepared dry and clean metal.
The bucket may be the safest solution, unless you have Ethelyne Glycol and your dog or cat drinks it a while before you can get them drunk on Jack Danials.....

You have been given good advice. A small crack in the block will expand with heat cycles. Stop leak preparations will give temporary relief. Welding will probably warp the block (unless as suggested) one finds a professional to do the welding. You should be looking for a block to rebuild. I have a 49 235 complete but you can probably find one close to home as the cost of the engine will be less than the shipping charge over a long distance. Jerry

Thanks for the advice. Sounds like the money pit is going to get deeper. Scott

`I would go the heavy duty block and radiator sealer route as you have nothing to loose.The older Barrs Leak that came in a glass jar would be my first choice.
