How To Paint Hi Temp Engine Parts?

[Driftwood]

I'm going to paint my 350 SB intake manifold after I get it hot tanked to remove all the old paint and crud. What's the best approach for painting? If I paint several coats with the Chevy orange paint can available at Auto Zone will it just peel off from the engine heat? If I need to bake the paint, which paint should I get and can/should I do it in my oven?

Any advice is appreciated.

Mid-America sells different types of paint for different parts and materials. Search through them. I remember seeing exaust manifold paint, but I'm sure they have something for intake. Good luck!!

I suggest you use Glyptal and while you are at it paint the valley under the intake for better oil return. Here is a link to buy Glyptal (listed by state) http://www.glyptal.com/Distributor.htm Its really a paint for electric motors and tested to a 1500 degree arc. And here is a few pics of an engine painted inside and out. http://www.autoblueprint.com/glyptal.shtml

I did Glyptal in the valley of my block. I didn't do it on the underside of my manifold though, that's a good idea. Be sure if you get a can of it, to shake it up VERY good, and make DAMN sure you don't get any in the lifter bores! (If you do, wipe it out immediately!) Glyptal is really something for an engine rebuild, as opposed to just cleaning up an intake, though.

Otherwise, if you're just looking to paint the intake (for appearance's sake) then some of the 500 degree paint (that does not require baking) usually works well, or you can get yourself a can of POR15 - which is REALLY nice. I used that on my intake. POR15 can be brushed on (because it's thick like house paint!) and will smooth out with a nice thick coat. An intake won't be exposed to extreme temperatures, so it won't burn off.

Por 15 makes a good paint system for engines now.Look on www.ketone.com .It comes with prep solution primers and topcoats.I heard its good stuff.

Andy:
I agree w/ Ken73 ... Glyptal is a good thing ... but not so practical unless everything's apart for total rebuild. Also agree intake doesn't get extremely hot ... plain old chevy orange engine enamel is fine. Let it air dry at room temp or above for a day ... no oven needed. If you scratch during install, just wash up w/ soapy water & dry before you first fire motor... then touch up first ... then fire motor ... it'll bake itself.

BTW, if you haven't already experienced it ... nothing quite like the wrath of a woman who's discovered her oven is used for car parts/solvents & house stinks of same ... it does stink up the house real bad for a long time. Many years ago ... did a hd panhead to install bronze guides that way ... first & last time. An old oven in the shop is handy ... but never the kitchen.
