Hi guys and gals...New to forum. Looking to diagnose a whining noise in my 94 tracker 5 sp. 4x4 138k. It seems to make whining noise (almost like it has a mild cam) when sitting idling with clutch out...By out I mean not pressed. When I press down on clutch it goes away. No noticeable noice when driving but it is a ragtop and rather noisy from wind. Any suggestions on diagnosis? Thanks in advance.
