Aluminum Intake Repair

Post by HS Nova »

Attached are a couple of pictures showing damage to the intake runners. I really want to run this vintage intake manifold. The pictures make the gouge look deeper. I would say damage in about a 16th inch deep. Is this even a issue if there is a small leak in the area between ports?

Please help in suggestions to make repair.
Thank in advance. HS Nova

File the edges to make sure nothing breaks off.
Put a dab of silicone there with the gasket, the silicone might or might not be there next time, not that big of a deal really.

Personally I'd just weld it and file it down, but I am privileged in that way.

I don't even want to know what I'll get charged for the one tack weld I need.

I would try epoxy, use a good epoxy and when cured file or shape it smooth.

That would take about 3 minutes to weld including turning on the machine, grinding the tungsten, turning on the bottle, putting on a helmet and gloves, etc. It's nothing any decent welder couldn't fix in minutes without charging a $100 minimum.

If you're going to surface the manifold, a good shop would also be able to heliarc it. If you're not going to surface it, use epoxy and a straight file to make it smooth with the flange. Put it on and don't worry about it.

I would use Marine Tex. I have used it for years. There are other good epoxies, but my experience is with Marine Tex.
