[Healeys] BJ8 radiator cap issue

[Per Schoerner]

Hi
I made a blanking sleeve from a small cat food can. With this the bypass 
hole is closed permanently. The thermostat is non sleeved, obviously, 
and has a little hole in it so there will be circulation, although very 
minor, while the engine is cold. My engine is still out of the car, so 
haven't tested it yet. If it doesn't work I'll remove it.
