Glyptal Engine Paint

[PetroleumJunkie412]

Anyone here used glyptal paint on the inside of their engines? Had @bobbywalter recommend it to me when I was talking to him about piston coatings. Didn't know if anyone here had personally used it.

Painting anything on the internals of an engine worries me, but Bobby made a few good points about the stuff, and the benefits it has for internal oiling and sludge prevention. Considering doing the heads, valley, etc on my 2.9. Have yet to pop one open thst doesn't have 30 years of disgusting sludge inside the valve covers, lower intake, etc.

Thoughts? Opinions?

I used in on a 429 years ago. I didn't keep the engine long enough to really say if it holds up over time but it definitely makes the rough cast surfaces super slick. The stuff I got was from eastwood.

Painted Internals are like running an open carb 429 Pontiac in the Mojave desert for 20 years, may work for some people.. But definitely not for me.

I've never done it because of the possibility of the paint peeling and getting into the oil. It's supposed to speed up oil drain back, I've opened drain back holes and ground off casting flash with a die grinder to get similar results. No engine that has proper maintenance will have sludge build up, painted or not. If I was going to paint inside an engine, I'd strip it down, have the block boiled at a machine shop, then wash the whole thing down with brake clean to try and insure good adhesion.

Yep, that's where I am with mine S far as prep goes. Already chamfered and ground off casting flash as part of block prep, and got the block and what's left of my internals back yesterday. Looking for any advantage I can gain on some of this stuff.

Make sure there's enough oil in the engine and change it frequently.

What do you change it to? haha. BTW. What the heck is petroleumjunkies avatar? What is that thing? It reminds me of Horus dressed up as sherlock holmes.

Now everyone is googling Horus.

Oil is slippery.

I've never painted the inside of an engine block. I have spent hours removing flash and smoothing out the rough edges though.

Use it, I'm not even sure how to pronounce it.

I was working with some oil that was sticky yesterday,

My buddy’s father swears by painting the inside of the valley. A tip I learned from him... only use oil based Rustoleum.
He owned a machine shop in the 70s, still has all the equipment, and builds race motors for a hobby. I Pulled apart a motor last year that he painted in 88-89 and none of it flaked off.
