... oh and I replace the diff oil a few months back and there was nothing of concern.

You have done/doing all of those things Dave, which is good. I don't know if you have made much use of your car but I found that after restoring my Amazon with all new bushes fitted that it got quieter the more I used it. I don't know if it's the same diffs as the Amazon but I replaced mine couple of months ago, the previous one having a rumbling, especially on left hand bends. A big difference.
Have a word with Simon at Brookhouse and he can advise or Rob at Amazon cars who used to rebuild diffs. A very specialised task.
And finally, leave the wife at home. You will never satisfy them. That is what I had to do and the remainder you will do to YOUR complete satisfaction!! (Tongue in cheek)

How did this project go?

Were the results good?

I'm looking to put some similar stuff on my new PV544

Does anyone know if the Dynomat stuff has been upgraded recently? In a forum test it was found to be more flammable than the bitumen based builders' stuff...

...I'm particularly concerned about fire especially as I want to insulate the bonnet.

You need to concentrate more on the firewall and trans' tunnel and perhaps under the rear seat.

Well, with a 2 hour trip, the car is probably tuned, but if not, try spending some time there.

I bought my pv444 about 10 months ago, and not only did the seller say the fumes were a problem, but I could also see his efforts to seal up any tiny holes in the firewall. I gave it my version of a tune-up and really spent some time to balance and then lean out the carburetors. These were dual SUs. The carb adjustments made a huge difference in reducing the fumes.

Check where the steering column goes through the firewall, also where the speedo cable goes through. Lift the gaiter where the gear lever goes through to the box. The felt here deteriorates with the heat and oil.

It was on one of the Mercedes forums I frequented a few years back. Someone was doing a build and had taken a blow torch to several of the options.

A formal test or a report it was not. It was a DIYer giving it a go. I was surprised to see that the builders solution behaved better than the solution that was designed specifically for engine bays...

okay

to share, not all dynamat product is designed for under bonnet installation. i looked into flammability testing of sound deadening product a couple of years ago when i fully lined the MGBV8, dynamat and some other products came out top of the list approvals-wise.
