I have the 352 fe with a 3 speed I have a tap in the left side of the engine I pulled valve covers checked for damage and checked for excessive wear, none noted. I have replaced spark plugs,exhaust manifold gaskets, nothing has taken care of the tap. It taps at all rpm's. i have checked for bent push rods and but not for bent valves. What else besides tearing it down could I check?
