I live in the Highlands in a rural area and my car is outside and not garaged.
The local mice are having a great time demolishing the heavy dense foam insulation under the engine cover on my SKoda Scout diesel. The little devils chew it into granules and it lodges in the depressions where the injectors enter the cylinder head. Also they have started gnawing the sleeving around the wires which activate the injectors.
On my previous Freelander they destroyed over the years the whole of the engine bulkhead insulation.
I've tried spraying the foam with WD40to see if it oputs them off, but it does'nt seem to.
Anyone out there with some words of wisdom??
