Well, has anyone done it? I would like to fill some of the holes that I don't need for asthetic purpose's. I could weld them, but I don't know anyone personally who would do it for cheap or free. Mazdatrix uses it for building engines and porting, heres the quote:

"JB WELD is a two-part epoxy for repairing, or building up metal. We use it in many different places - for filling ports when building peripheral engines, building up runners inside intake manifolds, backfilling behind ports when we know we will break through to the water jacket, filling EGR passages in center housings, etc. It is an extremely versatile material that adheres great to just about anything solid. It is very easy to sand or grind after it hardens, and can easily be built up in layers. Remains pliable for about 20 minutes after mixed (but can flow where you don't want it for a few hours), requires overnight to harden. The best "tool" we have found for applying it is popsicle sticks. Each box contains two 5 oz tubes - one of the JB material, and one of hardener"

If its good enough for inside an engine, then I think it would work fine for filling small holes in the engine bay. If this isn't a good solution, then I won't do it at all.

I don't know, what do you guys think?

Thanks

 

Anyone?

 

I used it to block the coolant passage on one of my housings for my FD that I believe was for the the extra coolant passage in the FCs.

Not that I don't think it won't hold because I plugged it with a homemade plug, packed it with jbweld, but using a freeze plug would of been so much easier.
