Default Valves tapping sound

Sometimes I hear it when the car is going on a slight hill. I'm in the right gear. Example (70mph in 5th). Why does it not have the tapping sound going downhill?

Educate me, what is the cause?

TIA

lack of oil, your oil runs to the back of your enjine and cant get sucked up easily.
thus noisy valves

well when your enjine has "little" oil in it itll take some time to get back in it wont kick in right away

or it could be a loose part that when angled rubs against ______

looks like your engine i knocking , could be bad gas, your timing is off, check these if your valves are off you would be able to hear the at idle

yeah, that's what I was thinking too. I doubt that valves would be noisy only when under a load and not at other times too. I'd check the timing too. When was your last tune-up? Have you ever replaced the fuel filter?
