Just tried something. My exhaust system on the ranger is a mess, crack in middle of converter shell, all joints are connected with flashing tin wrapped around them & tightened with stainless worm gear hose clamps. Well- at work we use this high-temp slicone like adhesive to join breaker cores to sand core sleeves. Its expensive stuff, comes in a 4 gallon bucket and is supposedly $400 a bucket. When a bucket is changed out theres a little left over, cant do anything with it, just wasted and the bucket gets tossed or sometimes someone will take one home, peel out the glue once it’s dried and have a bucket for whatever purpose. A month ago the exhaust came apart on the hhr where I removed a resonator a few years back and put a straight pipe in its place, the adapter I used had rusted apart. So I smeared some flashing tin with this stuff and wrapped the two halves of the exhaust back together, hose clamps again like Ive rigged on the ranger. Its held up so Ive decided to try it on the ranger. Its sticky, hard to get off your hands. But we will see how it holds up. Dont know much about this glue, brand name is “Valco” all it says on the bucket is “valco-aluminum “. I think the aluminum is just a color reference, since this is normally used in a foundry setting Im thinking it might work well for exhaust patching. I emptied a bucket today at work and its almost 40 outside so seemed like a good time to try it out, its been holding up ok on the car (which still has a functional catalytic converter) In about a month the oil will get changed on the car and the truck will be back on the road as my daily driver, should be plenty of time for this glue to cure. I didnt give the car much cure time, think it sat over the weekend. I have no idea how long the glued sand cores at work sit between assembly to when they get put in to use at a foundry. A lot of our product that use this adhesive go to laredo texas so that’s probably a good week between being made and being used. Be nice if the truck was a little quieter. Id replace the whole thing but Id need a manifold too and I cant find a good 94 2.3 manifold so its rigged the best I can. I think Ive just spent more time typing all this than it took to put that goop on my exhaust.
