05 E320 CDI INJECTOR COVER/ INSULATOR?

Hi, just got my first Benz and looking for advice. I had one injector leak an found the injector sound insulator (sponge/foam like cover had deteriorated. So my question. The Injector noise insulation cover like a foam/sponge cover has deteriorated and I want to replace it. Do u no a part number or exactly what it’s called. Thought I would ask the experts prior to calling the dealership. I couldn’t find the part online. Again thanks for any information

Here's what Mercedes EPC lists for that part.
6480160624
Also see attached picture
Upon a google search, the part is available. One third party retailer site I found lists it at $42 for the OEM Mercedes part. Some retailers may have a lower price.
Congrats on the CDI purchase and welcome to the forums. I recently got my CDI last December, loving it so far.

That foam is the material who create "black death" so don't put it on till you are 110% sure you have no leaks.
Lot of members decided to remove it just to prevent potential problems.

I agree with Kajtek. I removed mine several years ago and did not notice any increase in the noise level.

same. hard to have black death when no black exists. Plus it is one less thing to remove when I need to work on the topside of the engine

I removed mine, but I removed the foam. The plastic is sitting on the engine where it goes but doesn't provide sound dampening.

I can tell 100% sure black tar will appear even without that foam (my W210 270CDI did it without a foam...). Of course it will make things worse when mixing foam with hot black s*it coming from cylinder, and in early black death when only hot fumes will pass the injector seal foam probably start to melt.

I removed mine, so I would have extra one cheap because my W211 is gone... unfortunately sending package to US is PITA due to custom requirements

Don't know what customs has Finland, but I bought several parts from Poland with no customs.
If you agree to wait about 5 weeks - sea shipment is pretty cheap too.
