1996 GMC C1500 Sierra SL 4.3L Front of Engine
Knocking noise in lower engine first when started. It lasts for about 20-60 seconds. Sounds like rod bearings. Removed drive belt noise never changed. Has anyone seen this problem before, I'm a Chrysler [...] more when we received colder weather 0C and below.
