360 oil leak at back of intake manifold

Be carefull that is where the oil is comming from. I spent quite a time trying to find the source of an oil leak comming from the back of the engine. I eventually found that the oil pressure switch has a tapered thread and previous owner had over tightened that switch cracking the block.
After taking the engine out I cleaned the area and veed out the area and used JB weld in the crack and haven't had an issue since!
