Plastic thread stripped on airbox
So one of the two threads for the ECU bracket has finally given out on me. I knew it was going to happen eventually.
The new cover from Honda is like $53 so obviously I'd rather repair it than replace it. I'll be watching for a used one for an 03 in the for sale section so PM me if you know of one for sale.
I'm not really keen on the idea of using a helicoil or other thread insert since it seems to be hard to find one that matches the original dimensions and pitch of the bolt. I'd rather not have two different size bolts in there, but its just a phillips head so it wouldn't matter too much.
I've seen the loctite form-a-thread and it looks like the best option at this point, but its $25 shipped to me (can't find it locally) so if it doesn't work I'm already at half the cost of a new cover.
Similarly I've read of people coating the bolt with lube and JB weld then sticking all in the hole and letting the JB weld cure. This would probably be the cheapest option. I've honestly never used JB weld so I'm not familiar with how hard it is when it sets up. Could I just fill the hole completely with JB weld, drill it out, and let the coarse threads of the bolt form their own threads in the JB weld?
Any other options I'm not thinking of?
