Just rebuilt engine in car. It's the olds 403 engine. Why is coolant leaking between head and block? Machine shop said engine block was in great shape but heads had to be milled a little due to overheating in which the olds 403 are known to do. I put engine back together started it up. Sounded great but noticed coolant seeping between head and block.
