Im thinking a bent pushrod. What you guys think?
So do you ever change your oil? looks pretty black.Well I didnt have any choice but to drive the truck 250 miles back home. When I was 30 miles away from home the knock got louder and the truck threw 8 codes and I could only go 50 mph. It was weird because when I left the knock wasnt there but then It would come and go.
So far we found that the bridge for the valves some how came off, most likely due to over rev.
