Hy I´m new + lifter question

[stormy]

Hello,

first off I´m from Germany so my grama is a little bad (half American but it´s been a while since i have had to write

Anyway my M50 with vanos is anoying me with lifter ticking until it fully warms up (water gauge).

Tryed different Oils (Castrol 10W40, Lubro-Moly 5W40 and Castrol RS 0W-40) and still have the same problem. But runs most quiet with the 0W-40 when warmed up

Any clues?
