My 1990 silverado has a bad spark knock when under a load, I changed the
timing chain and gears (double roller) put in a new crankshat and new
bearings, replaced the knock sensor and put on a new throttle body
regulator and it still didn't go away, what else could this be? Thanks

I have had my truck since 1997 and it was just replaced and I don't know if
it was replaced before my truck has 90,000 miles on it. It would knock when
accelerating up hills and would not stop until I let off the gas. When the
EGR was changed it now knocks for about a second or two then stops when
knock senor does it's job.
