Filed under, "something to play with with old parts".
On my Mazda B2500 Turbodiesel (WL engine), gaskets blow off and on. Then you get the whistling and the potential to warp something as the hot air rushes out through the leak. It doesn't suck when this happen - it blows.
So I thought about it. I checked around, considering how to make my own gaskets and found some useful tips on how to do it. Soft metal is what is needed, copper isn't suggested for diesels (though I am uncertain as to exactly why, I expect it's because of the chemistry of the exhaust) and... that they all sort of look the same.
But why do they look the same? Why is it that no one has implemented a gasket with a design that is of a pipe form that fastens in the flange? Sure, if implemented without allowing for the external diameter of the gasket, it would be a small bottleneck and would probably produce some cavitation. So why not machine the parts on either end of the gasket accordingly?
Such a gasket might last a lot longer. And between gasket changes, I may try to make one of these gaskets to try it out... though I will have to get some parts bore out slightly to do it. Read more »
