Repainting Engine Blocks

[davbell22602]

By removing the casting flash and round the sharp edges and coners actually makes for a stronger block as most motor gurus that I have talked to say. That all so includes inside the block not just the outside and if you are worried about leaving any particels behind inside the block you can paint the inside with what they call block sealer.

I want more info on the paint block sealer for inside the block.

I saw guys do it with epoxy paint inside, as mentioned before helps with oil drain pan because it's slick inside and if you smooth it out it'd be even faster, they do inside the head(under the valve cover where the springs and rockers are, and the valley for the lifters.

Ok did some more research on painting the inside of the block. The whole block sealer thing is some magic additive for sealing leaky head gaskets (aka don't waste your time and create more problems and just replace the head gasket). Next this is a very time consumming project meaning all machiened surfaces have to be masked of i.e. cylinder bores, bearing surfaces, lifter ports, and so on. Next there is the fact that the paint either outside our inside the block holds in heat. But on the bright side of things I did find the paint that my book refered to. It is called GLYPTAL 1201 RED ENAMEL which runs about 50 bucks a quart or 50 for a 12.75 spray can.

I'll throw in my .02 here.

If black is your thing, I've had GREAT success with BBQ grill paint. It covers well, bakes pretty hard, and lasts.

If done properly, wrinkle finish looks good and also lasts a long time on the upper engine parts. I've painted several superchargers and Camaro/Firebird 3800 aluminum valve covers with wrinkle finish with great results.

No, I wanna use factory color which is old fold blue.

Whats this epoxy paint actually called and where you buy it at? I wanna paint the inside of my valves and maybe oil pan too.

 

[Swims350]

have to find my book and look. It wasn't the inside of the valve covers and oil pan though, it was the block itself in the lifter valley and the heads where the studs are and the bolts, and springs.

Ok, Well then what paint should for the inside of the valve covers and oil pan?

 

[Swims350]

not sure.

I think it was said before, "block sealer"? I never messed with the stuff, that's all I know.

 

[davbell22602]

Ok, I was hoping there would something else besides that.

 

[davbell22602]

Found it "oil shredding coating".

I went AZ to the Rustoleum paint and primer to repaint the engine block and other parts. What kind of paint remover/stripper do I need to remove the old paint? The rustoleum paint thinner can said its not recommended for removing paint. Can use regular paint thinner from lowes, etc?
