I'm not saying that changing the gasket is a bad idea. I just honestly want to know how many people actualy do it?

Of course I'd change the gasket on a real car. But there's a big difference between the side affects of destroying the engine in a vehicle worth tens of thousands of dollars, not being able to get to work, and then paying for repairs..........As opposed to possibly having some diff oil leakage in my toy truck that I might have to eventually re-fill.

For me, my LHS doesn't deal Mugen Seiki parts or cars. So I just reuse a gasket untill it becomes too physically worn to work properly.
