I had my friend tig weld my cast Mopar Performance valve cover. One of the corners cracked around the bolt hole. Just got to get it good and clean. Welded about 5 years ago. I put the valve cover on, so that you can't see it. Passenger side , in the back, lower hole.

In a roadside emergency, I glued a rear corner with bolt hole back on with the fast dry JB Weld. It held for thousands of miles and several months until the cover was replaced because of it. I believe it would still be fine to this day.

Thanks! Any suggestions on what rod material to use?
I'm on a project that is ballooning in complexity. I believe that I will need to add material and then remachine. Will post pics when I'm done.
Need to practice. My tig welding skills are rusty................

A general purpose aluminum rod will do just fine. I don't know what you're doing BUT get that sucker spotlessly clean first.. I'd run it through your parts washer then a couple cycles in your dishwasher. Then clean both the area and the rod with acetone just before welding. I need to move some bolt holes. Will de-grease it and I have a good industrial ultrasonic cleaner. Will put it through several cycles. Just finished welding my oil pan and it got the pan nice and clean for welding. I always clean with acetone as a final clean. I can tig weld just haven't done it in a couple years.
