My RC nitro monster truck has been going really well, but I have hit another cursed problem, which I have to seek help for.
The muffler/manifold assembly fell off the engine on Friday. I had no idea; just drove the truck over to refill it, and realised it had partially detached. The long screws and split/spring washers are still there (trapped in place by other structures) but the little gasket has gone (or maybe it simply disintegrated). The gasket was about 30mm long and 10mm deep (about 1.5 x 0.5 inches), with the “letterbox” rect** cutout for the exhaust port being a lot of this, and two holes for the screws at the ends.
Supposedly, likely disintegration of the gasket is what caused the screws to become loose under the intense operating vibrations in the first place, so there is lots of stuff on RC forums about not having a gasket at all, getting “gasket paper” roll from an auto supplies shop and cutting my own replacement, OR using some goo in a tube called RTV (room temperature vulcanising) silicone gasket maker, to “make” a gasket. This RTV seems to have a lot of support on forums, over cutting a gasket from a roll.
I’ve got NO problem cutting out a new gasket from a roll, but it is making the holes for the screws I would not know how to do; the material won't be able to have holes actually drilled in it (would just shred).
Please, can anyone give me any advice? Thanks!
