[C320-list] Furthur Questions on Insulating the Engine Cover

[Kirk McCullough]

Karl

Like Jeff, I did mine at least 4 years ago and have had no problems with it 
coming off. I used the hangers only on the top surface, but I used 2 rather 
than one. I did clean the surfaces with a cleaner, can't recall what it was, 
but then used a solvent after the cleaning.

I used some white gasket material I had left over from regasketing the 
fridge lids, to make a seal along the edges.

It works well and doesnt interfere with the Perkins.
