LOUD sound from steering pump or box? only on cold startups

just recently when i turn my steering wheel theres a loud moaning sound when i turn my steering wheel i suspect its either the pump or box (hope its not box).. probably will get a new pump since its cheap anyway...also will be changing PS hoses.

I have similar problem, my pump is only a year old, but when car is warmed up, it is fine.

where did you get the pump from? did it go away when you replaced it?

If you haven't done so already, you might might just check your power steering fluid level.

i just saw your 80hr thread about timing chain guides...if my engine sounds like it has a supercharger is that the chain rubbing against plastic?

I'm not sure what you mean by "...my engine sounds like it has a supercharger." If you search Youtube for BMW m62 timing chain guide failures, you should find several examples of noisy timing chains, which result from the slack created by wear in the guides.

It's a whining noise. I want to tackle the timing guides job myself but adjusting the timing itself seems so confusing to me.

Compare it to the 540 noises on Youtube. I think there are enough that you can find one pretty close to your sound. The poster will probably have some explanation with the video.

As for the repair procedure, these instructions are pretty good: G.A.S. BMW M62tu Master Cam Tools Instructions
