Epoxy for intake manifold
« on: April 17, 2018, 05:54:51 PM »
Hi all.. my custom i take manifold for 2 SU carburetors is almost finished but i need to do some filling around the mating surfaces on the intake ports.  The welds are a bit crude and I have had the mating surfaces surfaced on a head sander but there are some small areas that still need filled. And i also need to smooth and contour the interrior of the manifold ports  match the ports to the ports on the head.

I have read that some folks have used "epoxy" to partially fill the intake ports on a 2.0 and was wondering if any of you have had experience using JB Weld on an intake manifold.

I was contemplating using the "high temp" 500 F degree rated version and was wondering if it would hold up under the heat considering the head shouldnt get above 300 F

Heres a photo of the mating surfaces.

Any suggestions?

A quick Google search (intake ports epoxy) bought this up https://grassrootsmotorsports.com/forum/grm/epoxy-for-intake-port-shaping/32877/page1/

I'd say this is more of a general question for people who do head/intake porting than Pinto people in gerneral. Not say there aren't Pinto people with experience, just saying you are likely to find more info in a borader search. A word that does seem to pop upin this matter is Devcon. Not too sure but it seems an epoxy with aluminum particles inbedded from what I gather is a more stable heat expansion property. Anyway, try the Google - intake ports epoxy - search and you will likely be able to move forward. Do remember though that anything has the potential to dislodge and enter the engine. Hopefully you can find something that significantly minimized that.

Hi..

Thanks for the info..

I was also.worried about it possibly comming loose so I think ill play it safe and just have more weld built up and then shape it with a rotary file in a drill..
