Plus they looked fine whe I saw them. It sounds like this 1990 F150 5.0 V8 engine clanging.MPG - YouTube but much quieter. Please help. Truck has not run any different than normal

Given that this is a 7 year old thread, and that a 1990 Ford 5.0L doesn't have a cam sensor this probably isn't particularly helpful.
