I hate crush washers with a passion. On aluminum oil pans they have a tendency to strip threads from the torque required to seal them. These are for the mounting bolts right? I would switch to a washer of the same material as the bolt and just rtv the head and washer. If it leaks then **** it, let it leak. I mean, its not like a few drips are gonna hurt anything, just use some antisieze on the threads so the bolt doesn't get stuck. Other option if its big enough is to find a drain plug with a built in rubber seal and use that. Drain plug type gaskets would work as well but may not hold torque as well. The ideal solution would be to machine a groove around the bolt hole and use a rubber O ring with a flanged head bolt and get rid of the washer altogether. I like the drain plug bolt with built in rubber seal the best, if you can find something like that it would be ideal for cost effectiveness/effort/functionality.Hey casey, wondering if you would have a solution for this. Im a mechanic for a seawall and dock company. So we have a bunch of honda trash pumps. They pump salt water all day and never get flushed. So inside the pump there are 4 bolts that bolt the pump housing to the motor and they have aluminum crush washers on them to seal them. Well they last a couple months then corrode out, start leaking and now the bolts are loose and get stuck on the impeller.

Here a new one next to one of the better ones i replaced.
So what im wondering is there a crush washer that wont corrode out?
*edit: i know the easy solution would be to flush it at the end of the day. Thats not going to happen. Its not their equipment they dont care and will not do it
It's all good shit. There's 2 atvs and an off road mower under there. You should see the back yard.I see you're staying busy Casey. didn't waste any time packing that garage..hah.
