My Ride: 2001, 325i manual
Engine Noise

Hi everyone!

My 325i, 2001 has only 200,000 miles and there is a noise from the engine. It sounds like a roaring noise centered under the intake manifold that goes up and down periodically. It is more noticeable when I am starting it with the engine cold and at idle. Above idle the noise goes away.
Any good ideas?

use a hose to isolate the sound. 200K miles is so two years ago for me, baby!

Check sap which turns off a couple mins. after a cold start...also disa's rattle, but use a hose as stethoscope to isolate the location of the sound...careful of moving things!
