Hello, I have a 00 ML320 with 64k with maintenance up to date. Ive noticed recently after the initial crank it sounds like the valvetrain (lifters/rockers) ticking/knocking and then immediately goes away. I didnt know if this was part of the common lifter problem or just from oil not being in the heads on crank up. Either way, just checking to see if any one else has experience this type of noise. Ive got an ext warranty so hopefully if it is a problem, itll get corrected.

THanks in advance,
Brian
