Hi, my Indy, the insulation at the side walls,, the belt side is falling(starting) into the alt pully/belt.. is this insulation needed, I can't see it helping keep the noise out of the cabin, the firewall insulation does that.. other than a dirt collector, whats it there for?
I removed all of mine a long time ago. Dirty, itchy job but once it was off it's cleaner and not so itchy o work on. Leave the firewall section on. I didn't find it any louder once it was off.
