SR20det valvetrain: hydraulic lifters bleed themselves @ 120psi? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I was talking to a machine shop that builds sr20det engines. We are discussing the oem lifters for the sr20det engine.

According to him, the correct procedure for setting the valve clearance on the sr20det engine, is to

1. completely remove all of the oil from the lifters first
2. Install the dry lifter into the engine to check the "preload" and adjust the valve clearance
3. Pressure the oil system at 120psi of oil pressure to fill the oilpump, bearings, lifters, etc... when finished

I was under the impression that OEM sr20 lifters cannot bleed properly when installed, once there is air in them.
I quoted the FSM, which the engine builder said was a "standard procedure and does not apply in this case"
