And, basically my '04 E60 has the same engine with 127k miles and no issues.
BTW, no baffle. With all this said, the timing control on these engines is much more complicated than the engine in my E38 and as such the timing tools might be a good idea. Also, if you need to replace the guides, you might as well replace the valve stem seals since you will be so far into the engine. I just did them on my E60 and it was a royal PITA, but stopped all engine oil consumption issues. I purchased the AGA tool for this purpose.
Good luck.

after taking your post in consideration, I went back to check my car again, I used brake cleaner and sprayed all the moving part on the belt, when I got to the water pump the noise got softer, this pump was replaced a month ago, it is the HEPU metal impella, so it was the last thing I would suspect, I took the fan belt off before and turn the pump and it seem fine to me, but I guess under load the bearing makes noise, I put the old OE pump back in with some new hoses that needed replacing and the noise is gone for now, I have the timing tool along with all the guides and gasket on hand now, I will still replace it hopefully in the summer when I complete my garage, "Truckedup" mention the water pump that is why I went back to take a second look at it, thank you guys for all the information you provided, I learned a lot more now to complete the work in the future.
FCP Euro said they would give me a refund or replacement pump, this time I will get the OE pump,
thanks to Davidf, truckedup, for the help.
