I have extra heat shields; that wouldn't be a problem. I'm just short on spare time. I also have no garage or indoor workspace, and it's getting cold where I live, which makes the hard-line wrench dance a lot less fun. I'm just wondering how much I should prioritize this over other tasks to get it done before winter sets in properly, or whether it would be futile now that I've already over-torqued. I'll likely be learning how to re-build injectors sometime next summer, and could get new nozzles (if these are damaged) and go at it all again then.
