I remember back in the day (long... LONG! .ago...) guys did that to help oil drain back, but that was on cast iron with the usual rough finish. Not sure it helps with these smoother aluminum blocks.

I also recall the same thing in a number of engines (admittedly a couple of those were mine). I was told it was to "seal" the fine grit/debris from blasting, machining and honing.

There really is no good reason to do it today. All it is going to do is flake off after a short amount of time and end up in your oil filter and/or bearings. It will do absolutely ZERO for oil drain back or performance.

^^^^ I have to agree. LS aluminum especially is smoother, and have no issues with drainback. Not sure it did any good back in the day either.

What you see is "Glyptal", not just paint... And I have been applying it to hundreds of engines over the years.

After thorough cleaning... The "Glyptal" is brushed on and then cured in an industrial oven. I have NEVER had it flake off of an engine. It lasts forever if applied correctly.

I apply it to any heads and cylinder blocks that I assemble, as long as they are not machined from Billet.

It should be applied anywhere oil will drain, the speed in which oil returns will be accelerated.

The C6 Vette oil pan I purchased for this engine only holds 5.5 quarts...

I do not want most of the oil staying up top. Which these engines tend to do especially with a high pressure and/ or high volume pump.

Aluminum is very porous... So I used it to seal the block and heads. Other wise oil seeps into the aluminum. It also helps some with drain-back.

Note: Do Not apply it to any machined or smooth surface... Adhesion will not be adequate.

Going back to the questions in my last post...

Any recommendations on Heads and are many of you running a SQUARE engine (4" bore X 4" stroke) ???

VortecIroc, and to everyone else looking at junkyard or pullout engines, this guide seems to be spot on and has tons of information.

How hot does Glyptal have. to bake?

Curing time will vary depending on material and size of the object.

The aluminum engines usually go in the oven for about 1.5 to 2.0 hours at 250.00*F.
