I'm done with this thread, I thought it was a rational discussion.OK, you just got crazy.
Don't expect rationality from those who are blinded by the windmills not turning.
AS Trav pointed out, the materials in question for valve seats are powdered metal, specifically, metal carbides. The basic process is you take a metal carbide "dust" and squeeze it into to the shape you want. Some manuf. may heat treat it afterwards. The metal carbide dust may be carbides of special steel alloys, cobalts, etc.
Oilite bearings are manf. in a similar, but not the same manner.
Copper particles are infused to increase heat conduction of the seats so the heat is conducted more efficiently to the head.
Whether it be sintered Oilite bearings or specially processed carbide valve seats, they are both porous materials.
The only way to really show that any liquid can penetrate below the surface of a steel material (as explained in a previous thread), is to take something like 4140 tool steel and pour the liquid on the surface or submerse it in the fluid, then dry it off and cut the specimen in half.
Then take a micro photograph of the sliced specimen at high magnification, showing the surface and the material underneath the surface.
Pouring any thin oil on a porous material and watching it migrate is cool. It is called "wicking."
Showing this effect and then saying that it penetrates solid metal or solid metals particles is a ruse.
Maybe Dave and Dale would like to engage in Q&A sessions here:
