Strange wine from motor under load

Hi guys,

what may be the reason behind this whine from 4k RPM?
1994 auto trans VG maxima from Germany. Noise is only appearing under load. No whine when reving in neutral.

Alternator? Timing belt? pulley? Transmission?

Unfortunately, it could be anything. Seems like it is responding to vibration at a certain frequency. Could be mechanical, could be items inside the cabin rattling against each other.

supercharger/turbo winding up?

if it's only under load (driving) it's very possible it's transmission related.


alternator and etc you would probably hear it revving at idle.

No turbo/supercharger is present

Sound is clearly coming from passenger side, so I ruled out the transmission.

I also hear strange sound under the rear valve cover, but as far as I know the valves are hydraulically lifted. Maybe that is the reason? Valves emit those sounds even reving in neutral. It is not a whiny sound, but it is not as smooth sound as from under the front valve cover. What should I do about that sound? Seems that under load and at 4k+ RPM that valve sound changes to the whine from video. Do I have a bigger problem?

"Strange wine from motor under load"
is it the taste? was it a bad year?
maybe stored improperly??


"No wine when reving in neutral"
i would advise this, as it is unsafe to operate a motor vehicle while consuming alcohol
