Recommendations
The bulkhead soundproofing is the foam located in the engine compartment at the rear of the carburetor.
This soundproofing has the major disadvantage of retaining moisture and causing oxidation of the bulkhead. In addition, over the years, it has become seriously ugly and is starting to crumble. We have therefore decided to remove it permanently.
Removing the soundproofing also allows you to see much better and be much more comfortable to work on the wiring harness and heating hoses later.
Opinions are divided regarding the removal of the bulkhead soundproofing. Some Mini enthusiasts believe that the increase in noise in the passenger compartment is too great. To each their own priorities.
