If you have a mechanics stethoscope, use it to more clearly find the exact
location of the noise. Place the probe on various locations at the engine
accessories and you can hear the noise source.

Having heard the engine running, I would pull the valve cover and check to
see if a valve adjuster didn't get locked down and backed out enough to
clack hard. The rhythm of the clack suggests to me it is a valve train
related noise... if not an adjuster, then, dig further to other things.
On Sun,
Those are diaphragm type pumps run by a plunger, not a set of rollers. If you
don't get the bolt right, they clank.

They don't last forever. I had to rebuild my W116 pump when I got the car.

Ah, yes. I forgot that. I did have to rebuild the vacuum pump on my 220D,
but I don't remember why.

Wound up having to rebuild the vacuum pump on my 220D. That, Diesel Purge
and pencil glow plugs improved matters considerably.

These have manual shutoff, no vacuum. It could be the vacuum pump making noise.

I would have said pull the valve cover and look at the rocker arms until
you opened the fill cap and the sound didn't change. You had vacuum to kill
it, so not the vacuum pump. A rod???

Finally got it to run. Supposedly engine was rebuilt and within a short period
of time, it started making noise. I see what they are talking about. Need to
figure out if it’s serous or something simple.
