Either way it still works. Reducing ACH and insulating a house both save energy. ACH meaning air changes per hour. But basically sealing the envelope helps a lot just like insulation.
The big one being it seals off the top of the motor from air flow, but when you walk away from the car it doesn't cool down so quickly. Cruising down the road the sealing of the head with some insulation like i did more or less reduced the forced cooling over the head.
I agree though thats why i brought up my example with engine bay leaks earlier.
