I adjusted the valves 3 days ago. The first day was nice, no lifter tick, more power. The 2nd day i started to hear a bit of what i thought was a knock. My lifters never ticked at idle or low rpm previously. But if i got on it at all they would almost sing.

Now its doing nearly the same thing.... At low rpm and idle the truck sounds great. Get on it even a little bit its sounds like frogs on a pond at dusk. All high pitched and chirpy. But it still runs good, i havent lost any power.

Im thinkin its a bent or a burnt valve but at this point i need some outside assistance.
