Magnesium Intake Repair
Not sure if this is the correct forum but I have an old Doug Nash intake that has corrosion in the runners and was hoping for advice on what to use to repair it? I was thinking of using JB Weld but I'm afraid of it failing and breaking apart and entering the engine.

Thanks John, I didn't think magnesium was weldable. Thanks for the link.

Balzona 1111 is the way I would go unless you can do / afford the welding yourself.
If you weld that then the flange will warp done and need to be milled adding to the cost.

Thanks Steve! Didn't know about that product. But wow is that stuff expensive!
The more I look at it I'm worried that the wall thickness is too thin for welding. |

My friend and mentor (machining) repairs (welds and machines)magnesium stuff regularly. He's an old school machinist and drag racer from Canada, 76 years old, grew up on a farm and went through Canada's apprenticeship program. Hopefully Canada still has such programs going.
I would think you can find some of these old school types in your area. |

New64Owner, I did find out about an old race shop about 45 minutes from that welds magnesium. Haven't called yet. |

Its great stuff,is original designed for the marine industry.Sets up under water.Have seen props repaired with it.I have found the best way to mix is to get a 5 gal bucket,fill about 1/2 full of water.Take a golfball size ball of each and mix and need it underwater.It will become a greenish color when mixed well.I first saw Darin Morgan using it and selling it for the racing industry.I have used it for maybe 30 years or so.Tom

My machinist worked for Crane for years. Didn't move when the company did. For the past 30 years he has been building Suziki race engines, and does most of the Porsche machining in the So Fla area. He uses a contractors epoxy we originally bought from Builders Square, then Home Depot. It used to cost 90 bucks for the 2 part 2 can kit. He uses it for port shaping among other things. You can use it under water also. We have a kit we bought 15 years ago and still use it. It's the strongest epoxy I have ever used, and I'm no amateur mechanic. The stuff Tom S recommends is probably the same type of stuff, and I fully agree with him.

Magnesium welding isn't for the faint of heart! If not performed in the correct atmosphere with the appropriate shielding gas, you could end up with a fire that only sand can extinguish. This and its reactivity are way aircraft manufacturer has gotten away from using magnesium parts.
