I took off the brake vacuum hose and poured in a can of seam foam which made it sound more like valve noise and less like rod knock. I've got one of those valve compression tools from a friend and I'm planning to put engine TDC on 6, hook compression gauge to air compressor and remove and replace that valve spring. I might also hook the valve to a cordless drill and try to spin it in case its just a big piece of carbon.
