525i Clickity-clack Noises

[Rowdyman]

Hello to all:
New to forum, 1995 525i new to me, and intermittant clickity-clack noises are new sounds from engine. I pinpointed noises as coming from a metal cannister, front left and top part of the engine just behind the top radiator hose. Cannister is about the size of an oil filter, appears to have a lid on held on by a nut at the top. I will buy a self-help manual tomorrow, but until then any help would be appreciated. What is that cannister and what could be causing the clickity-clack noises.

Thanks in advance

Sounds like the oil filter canister. It probablty isnt making the noise but more likely the noise is coming from something connected to it, likely causes would be the water pump, or possibly a belt tensioner pulley. With the engine off grab the front engine fan and try wiggling it while watching the pulley on the water pump, see if there is a lot of play there, if so then the waterpump bearing is prob shot. beyond that you may want to listen to it while running with a stethescope or long screwdriver acting as a stethescope to narrow down where the noise is coming from.

I believe that is the evaporator for the AC. It's probably not tightened to the rest of the engine bay and it rattles back and forth.

Unfortunately 3 different auto parts stores do not have 1995 maintenance manuals. Went out this morning started the BMW and listened again with stethoscope. The clickity-clack sounds are definately coming from that cannister. I moved the stethoscope all round the engine, even where the cannister is mounted and the sound is very loud from the cannister. Maybe a better description of the sound is that my gas engine now sounds like a diesel engine. I checked the fan for movement thinking it might be water pump bearings but it is solid. Whatever is in that cannister it sounds like it is turning or atleast has some rotary movement. Monday I will take it into the shop.

Order the bentley service manual for the e34, it is one of the best manuals out there.
