After retiming the engine, i noticed a new "rattle". Seems like it's coming from about the middle, around cylinders 3&4. Sounds like a loose nut is moving around somehow. i've removed the valve cover and nothing obvious. The engine runs fine and sounds fine other than the rattle. I've removed the pushrod cover, nothing to report. it's definitely inside the engine. any ideas?
thanks a bunch,
Many Blessings,
