Was driving from Boston to Conneticut and all of a sudden started to hear a tappity sound from front right. Pulled into lay by and sound was coming from right side of engine but not consistently. Increased in intensity but not sound when engine was revved. Continued drive and there were times when sound was not there at all and then it would come back with no set speed or acceleration determining when the tapping sound came. Definitely coming from the rocker area of engine.
She has 115,000 miles on it and is due exhaust manifold gaskets and a complete exhaust…..
Comments suggestions or otherwise so as to help identify the culprit….
She’s a 2000 P38 4.6 …….
