Customer Question
Hi we have a...

Hi we have a 2003 BMW 325i and just installed new ps pump/reservoir/hoses. Also new OFHG so took out alternator (+pulleys in that areas) because wanted to clean up oil leak area on/behind housing

Mechanic's Assistant: Have you ever replaced the gaskets? Maybe the hoses?

Sorry not through tryping... sent first part because can't go back to view what already typed (using phone might be issue). Anyway, there are 2 different noises now. One sounds like rocks in engine and other sounds like crackling. I've noticed tumbling rocks noise usually only occurs upon start up but then goes away after acceleration. Whereas crackling(?) noise only occurs while driving. Any ideas? We did not torque anything to certain amount by the way. So could a pulley (tensioner?) be causing crackling/squeaking?

Mechanic's Assistant: Are you fixing your BMW 325I yourself? What have you tried so far?

We did work ourselves and have worked on car many times before no problems. However never taken out alternator/tensionser/ofh before and realized some things might need torquing to specs.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just need help with weird noises. If alternator is bad or if pulleys aren't torqued correctly. Thx
