Anyone installed a radiator cover?

There are two circuits in the oil flow system. The main circuit pushes oil through the oil filter and then to the crank and rod bearings, cams, balancer and transmission.

The smaller circuit pushes unfiltered oil through the oil cooler and then around the jackets encircling the spark plugs, then dumps it back into the sump unrestricted, not through any bearings. I doubt that the oil in that circuit would get cold enough to need to cover the cooler.

I doubt the oil cooler would be damaged up there, but on the other hand, I doubt the protective guard would do any harm either.
