Any ideas on cheap thermo barriers for intake bottoms?

[LowBuckX]

Was just brain storming some ideas on keeping the heat off the bottom of my intake. Are there any thermo barriers that can be bought and done your self.
Or old tricks that you have done. I was planning to use one of the oil splash sheilds available but you cant use em with roller lifters.
Im not looking to do anything that involves stinking up my oven or buying an old oven to ruin.
What about running my PCV valve in the intake to suck the heat off the "roof"?? sounds good in theory but Im thinking that it would suck alot of oil too.

Here's a link to an article from an issue of PHR around a year ago called Cheap Swill (http://www.popularhotrodding.com/enginemasters/articles/chevrolet/smallblock/0503em_small_block_engine_build/) by Scott Parkhurst. It talks about a thermal coating they put on the pistons and valves of a low-octane / high performance 383 to isolate them from the heat inside the combustion chamber. The coating is called Calico CT-2. If you can coat valves and pistons with it, I can't imagine why you couldn't do it to the bottom face of an intake. IIRC, the author is a member here and posts under his name. I think there was actually a big post on here about the article...I'll try to find it.

Ok, found the thread: https://www.pro-touring.com/forum/showthread.php?t=18317

And here's a link to the Calico's website: www.calicocoatings.com (http://www.calicocoatings.com)

Don't know if any of that will help or not, but good luck. Let us know what you come up with :twothumbs

EDIT: well, I just went back and re-read your post and saw that you were looking for coatings that can be done yourself. So the stuff I posted may be not what you're looking for...whoops :hand:

me and my father did the same thing on his 33 ford 2door sedan,exept instead of a pvc we drilled and tapped 3/4" hole and used a 4" long tube and installed a baffle then a K&N breather. It was also on the exact same intake as this one #7546. I think as long as you installed a tube of some length and a baffle you shoudnt suck any oil. And it doubled for an oil fill location because he did not want to punch a hole in the valve covers the old M/T finned covers
