Kent: If the knock or taping noise is in fact a piston pin, what is likely to happen if I keep driving the car. I just returned from a 360 mile trip and the noise has not changed.
From a stop light as engine speed reachs 2000 RPM a taping or knocking can be heard. The sound remains thru 2400 RPM at which time it either quits or I cannot here it for road noise.
