360 oiling problem under load

It may have never stopped with that lifter loading it's valve before...Or you are really looking for every little thing now!
Not sure whats up with the ticking lifter or if its just a bad lifter. It ticks after sitting for a night but goes away almost instantly. Im sure its not gonna fix itself, but iv got a new set of Comp Cams hyd i can put in. Not sure where those summit lifters are made, but i dont trust them now. Bad check valve letting it bleed off overnight so how long b4 the next one goes
