Hi All
Does anyone know what the purpose of the No 2 cylinder block insulator is ?
This is positioned between the rear timing belt cover and the water pump on a 1hd-ft 80 series also would be on 1hd-dye I would guess.
It is made of high density type foam like material
There is more of this along the cylinder head as well as between injector pump and block
Is it for noise or vibration or to reduce heat transfer to the timing belt ????
Regards Geoff
