In the last message I mentioned the excellent phone support from Rustoleum concerning their high temperature paint, where they wanted to make a paint job work, but causing a domestic issue with use of the home oven for car work. was not recommended.

I "got to looking" at the manifold, and noticed that the surfaces that faces the engine,? where the gaskets cover up the sins, were pretty corroded/rusted, and on cyl #4 the manifold had eroded away enough to make the gasket surfaces quite narrow, with pitted areas elsewhere.?? A friend suggested taping sandpaper to the workbench and going at it to renew the surface.? YouTube provided someone that used 60 grit 3M wet/dry? paper,? (amazed to find it at True Value)? 3 pieces, attached with two sided tape top and bottom to a flat surface for the work.? Sanded wet; I wore out three sheets, bought some more paper, sanded another hour,? and called it good.? My expert adviser said I needed to be within .020" of an inch compared to flat; I measured .010".? I think I sanded off over 1/8".? #4 is now nearly as wide as original, mostly it looks like a new surface, pits and rust gone,? a big improvement.?? I spent a few minutes today sanding out the scratches with 220 grit paper.

It is now possible to get new manifolds for this engine, but who knows how good they are, etc.?

Good project for arm exercise on a very rainy day.?
