after removing the drain plugs from the block to drain the coolant, i noticed that the passengers side was dripping from the plug and around it. after cleaning all of the dirt i could see water dripping from the side of the block. the crack is running parallel to the oil pan flange starting at the drain plug going towards the front of the car a few inches. i did not force the bolt with a hammer or anything like that. i know it can be welded but that means pulling out the engine. is there anything that can be done to stop it. i cleaned off the area and put some JB weld to see if that will work. i'm still waiting for it to fully cure. i'll try anything to stop it before pulling the engine.
the car is a 75 with an l48 350 with 84,000 miles.
Have you ever tried Moroso's Ceramic or All Weather Engine Seal?

I've seen this product do some amazing stuff. It's definitely easier, and far cheaper, than pulling the engine. Good Luck.
