1997 GMC Sierra 3500 wear spot on the cam



what will happen if I drive my 1997 gmc 3500 with the 454 in it with a worn spot on the cam and the pushrod not working also a crushed lifter


Well, if you keep driving this, the metal shavings it creates will end up in places that will cause more damage that will make more metal shavings to cause even MORE damage until it just stops running.
