Engine Ticking Noise Rythmic

mults

I may be wrong, but IMHO, it sounds like valve noise. Like the old cars where the valves would float on the cam at certain RPMS. Since these are probably hydraulically driven, if the oil pressure is low, there is not enough pressure to keep the lifters on the cams.

I found this in my FSM for assistance in diagnosing where and what the noise may be caused by...

Would this cause loss in power or vibrations?

Both.

Well what’s weird is it’s got the same power still pulls hard all the way through the band even between 2-4K, the noise, (not pushing it like I used to but I had to see what would happen) and heck just switching to the redline after this noise started has made it smoother.

I think my next option is to find a decent oil pressure gauge.
