Has anyone got any ideas on whether lifter / tappet noise at idle is normal on the 32 motor? With just over 11000 miles my 32 has developed a noisy right rear lifter. There is a noticeable rattle / ticking at idle and the specific lifter has been identified with a mechanics stethoscope. It only rattles / ticks once the motor is fully warm, nothing is noticeable when driving normally and the revs are up and power seems normal. Is this something I should be badgering the dealer about or something that should be accepted as normal for this engine? Any input / comments much appreciated.
