I recently discovered a small oil leak, more like an oil seep, on the short deck between the head and the block, right by the power steering pump. It's not from the pump or the valve cover gasket. So, the question is do I tighten the head bolts on a car that has never had the heads removed since it was installed in 1974, and run the risk of breaking a head bolt, or just leave it alone?
