Helllo,
I recently posted about the ticking in my 4.3 liter Vortec in a 97 Sonoma. I have change the lifters, push rods and rocker arms, has a new fuel injection system, pulled off a wire at a time to see if it was a wrist pin, no change, took off the belt to check the tensioner, no change. I've heard about a balance shaft tensioner (or something like that) and timing chain problems as well. The truck runs strong and I have no problem with it blowing smoke. Instead of continuing to throw parts in it I believe the problem is so common that someone has to know what it is. I was at Home Depot the other day and a Blazer pulled up next to me making the same sound and ther are alot of videos on youtube with engines making the same noise. Somebody that really knows what the problem is PLEASE HELP!
Thank you!!!
