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.

Ignore it, it will have zero effect on the engine's operation. It's not like it can leak to atmosphere; it will just create an immeasurably small back-and-forth flow between the two runners, depending on which cylinder is on its intake stroke.
