Husky, what is the result? Have you found the problem? If so, please share it with us. Helps others diagnose similar.

I've gotta walk my dog first this morning, then I'm starting with the air cleaner mounts. Hopefully it will be an easy fix though I suspect the exhaust manifold gasket is shot.

I've come to the realization that all cars, trucks and SUVs require ongoing maintenance. Captain Obvious here, but in a way, we have ALL become slaves to our cars.......

When I had the intake and exhaust manifolds off I found that the Exhaust manifold was a bit warped. If you remove the manifolds find something flat to sit them on and take look under them.

On my Chevy Astro Van I had no issues removing the Exhaust Manifolds but when I put one bad on I found it had warped enough off of the engine for 3 Months that it would not slide easily over the studs. I found both Exhaust Manifolds were warped and needed resurfacing.

Houston, we have found a problem.

It ended up being a broken air cleaner mount. I had to tear the house apart looking for the cheap URO air cleaner mounts I knew I had somewhere.......replaced the broken mount and fired up the engine.....but heard a knocking sound at idle so I knew something wasn't right......

So, went back and re-read your post and checked the placement of the drain tube on the bottom of the air filter housing. Dummy me, I had not lined it up properly so off came the air cleaner again. After taking care of that issue, started the car and AHHHHHHH, the sweet sweet sound of a mercedes 617 diesel running properly!

I am planning on keeping an eye on the cheap URO air cleaner mounts....hopefully I can source the OEM mounts somewhere (mercedes-benz ARE YOU LISTENING????).

No, they don't care about us classic Benz owners.

Good job Husky.

Good job. The mounts that are $1.00 each are junk.

Pelican Parts does list genuine MBZ air cleaner mounts at $22.75 each. There is also a heat shield for the mount that is offered by Pelican.

The heat shields will definitely make the mounts last longer. I also drilled out the holes in the air filter can to eliminate shear stress to the mounts. Mine (URO) have been in there about 4 years so far.

drilling out the holes in the air filter can to eliminate shear stress sounds like a good idea; also, I tried screwing a lock nut on the bottom of one of the mounts to hold it better to the engine mount. It didn't seem to want to screw on all the way. I'm wondering if using a lock washer along with a regular nut would be better?

Can't hurt but a regular nut would work if it threads all the way. The mounts screw into the support arm and a nut underneath is like double-nutting and should lock fine.

If I remember correctly, the original rubber MBZ mounts are in the shape of a hex as compared to the round shape of the rubber commonly used in after market mounts. Probably the shape and quality of the rubber along with the heat shields add to the longevity of life to the MBZ mounts. Pretty pricey but maybe worth the price.

Disagree without prejudice. You can replace the URO mounts 10 times for the price of the MB mounts. In my case, by opening the bolt holes a little so you don't have to stress the mounts while installing the can and using the heat shields, my URO mounts are still working fine after 4 years. It also helps if you tune your engine to minimize vibration.
