I hadn't quite appreciated what was happening

Hi MrX,

Excuse the ignorance, but I hadn't appreciated:
(a) what a heat shield is, and
(b) what problem was being solved!

So I have found out that a heat shield protects parts of the underside of a car from the heat of the exhaust pipe(s). It's a formed sheet of metal that is bolted to the underside of the car.

The problem was that the mounting holes in the metal sheet had corroded and become larger than the bolts and washers holding it on, leading to nasty rattling. The metal tin lids with holes drilled in them act as giant washers, holding the shield on again and preventing rattling!

I realise that this was a great hack - now I understand it!

Oops

Hi Dave, oops. I think I have a habit of doing this sort of thing. I can only apologise to yourself and to any potential listener. I’m glad you managed to solve the mystery in the end and to explain it so eloquently. If only I had said something similar in my episode. Must remember in future to engage the brain before engaging the mouth :)

All the best MrX

Appreciation for episode

Simple and elegant, use what you have! I always love listening to your episodes! I used stainless hose clamps on my 2005 Tacoma catalytic converter heat shield, as I was not so fortunate to have a bolted on one. So far they have lasted 5 years in case your lids meet an untimely demise.
