And most likely lifters are beginning to drop oil presure with a hot engine oil not cold.
So it would be the other way around with hydraulic lifters or am I wrong?
Im a litle lost in this problem.

With regard to oil temperature & pressure, the leakdown rate of the compensators (lifters) will be slightly greater at higher temperatures, which will in turn lead to slightly later timing and lower lift of the inlet valves, which may be just enough to eliminate the valve to piston interference.
