barrylight 0 Posted August 28, 2015 AI rule 7.4.8 regarding holes in firewall and floor refers you to CCR. I cannot find anything in CCR about this. Do I need to look somewhere else in particular? Quote Share this post Link to post Share on other sites
Balroks 0 Posted August 31, 2015 If I remember right it's mixed in with some other rules, but basically all firewall holes must be covered/sealed properly. No huge gaps for nice oil fires at speed to make their way onto your feet. So for example having a half inch hole with a half inch wire loom running tightly through it is fine while an unused 2x6" hole where your A/C used to be is not.
