2-3 turns doesn't bottom any lifter I have come across. A brand new Comp hydro roller takes over 5.

the seat or cup will not stay stationary, the effective height changes all the time. The more pre-load you run the lower the rpm you'll float (lifter pump up} the engine. The more pre-load you run effects the vacuum at idle, and quality of the idle. I'm not talking about enough pre-load to collapse the lifter either. The less pre-load the higher the rpm potential. A race hydraulic lifter will have a robust snap ring and suggest little to no pre-load. A half turn ether way setting valves always has a noticeable effect on the engine. Let alone 2-3.

Back to the original post unless you have less than a quarter turn of pre-load that shouldn't have caused the issue. I will say though a 1/4 turn of pre-load typically that will be noisy (they run good there though). My guess would be a collapsed (bled down) lifter at startup stuck for a second. How much pre-load are you using? What brand lifter?
