Port filler material

Well, i have been out hunting all morning for the usuall stuff i use to fill combustion chambers and such and even after another product that was recomended to me for filing th port on a case reed engine. Problem is i can't find any o the ones i like or have been told to use (well there's only 2 so far)

So i ask you guys, what is something that will sithstand the heat and fuel/oil mix that i can fill the port with and wont' come apart while running the engine



I don't like JB weld but i'm taking all suggestions, but please only speak up if you've used the product INSIDE the engine or to fill the port, as suggestions of what people use on their bird baths, plumbing lins and such are plentifull, but not what i need

please help me

I've always used devcon titanium putty. But it is a little pricy.

ahh.. couldn't find that one, i got some devcon epoxy and a few other things to test today and when they dry i'll heat test em with an O/A torch and soak em in gas to see what holds up...

i wish i could find the plain epoxy resin i use to use but seems i cna only find stuff that "contains epoxy resin"

and most stuff is only good to 250*F

Ask the engine builders, pretty sure they can help you out. As far as I know, its epoxy, which is what I would use. Over here in Austria I get all my epoxy/glass/carbon stuff from a spe#*#*#*#*#*#*t store. They stock high-temp stuff too. I am sure you guys have it over there.

Checked a few sites, there are many. This one has adhesives that go to 4000 F (wow)

Epoxies and ceramic adhesives...

You fill the intake port because it's unused on a reed case motor and only adds volume, and disturbs airflow if you cut a fifth port. You really wouldn't even be able to utilize extra transfers if you didn't fill the old intake port, because most of the airflow would end up in the intake passage.

Dubsak is correct, by filling it you crate an area where you can add the 5th or in my case 5th and 6th transfer ports.

I usually use a product called "epoxy resin" which is a ingredient in most epoxies, but without the extra dditives. I've used it in 1:1 engines to re-shape heads and it never let go, so i would like to use that but can't find it locally and would have to order. I've seen the ESP heads for TS reed engines and they have a grey colored material like JB weld in them but i want to know if there is anything "normal" i cna use as i don't want to wait a week just to fill the port so i cna cut the tranfers. I'm hoping to have teh engine up and running by the weekend and this is all that's holding me back.


you would shrink the transfers with epoxy in order to reshape the ports for a lower RPM engine to make great torque.

I have used Devcon on a carb when I removed the choke. Had no problems with it.

The only products I trust in my intake manifolds/ports are the Devcon "Aluminum Putty" and "Liquid Alumimum". Both are available at Grainger supply.

EDIT: http://www.devcon.com/prodfiles/pdfs/fam_tds_107.pdf for the putty and http://www.devcon.com/prodfiles/pdfs/fam_tds_108.pdf for the liquid.
