It is a labor intensive job that you shouldn't need to do unless your lifters are very dirty. What makes you think you need to bleed your lifters manually? They should bleed automatically with oil pressure from your oil pump.

That is the nature of the beast, hydraulic lifters tick a little bit. If they are ticking a lot and it is concerning you, then I'd replace them. I actually have a set that I completely disassembled, cleaned, and reassembled if you decide to go that route.

Do you know what your oil pressure is at idle and higher rpms?

You can find a difference in noise just from the oil. what oil are you running? I vary weights from summer to winter

I sent my lifters off to Mizpah performance, or mizpah manufacturing or something like that. After shipping I think it was around $80. My valve train was kind of noisy while the lifters pressurised, but now make little to no noise at all. I run 10w 30 Mobil 1 synthetic.
