Well I got my $12 mini borescope for my phone. Had to get a micro USB to C adaptor. Right angle mirror attachment doesnt work too well. Pix with it are not very clear. Other than that, this thing is "tits". I bought it to look around inside the cowl at the standpipes and other low lying areas inside there where water tends to sit at both ends.
The lower plenum is surprisingly real solid. Better than I thought it would be. Some minor surface rust spots but easily cleaned up and sealed. With AMD doing closeout sales on the lower plenums I wanted to be sure if I needed one of these, to get one now before they are gone. So the $12 was worth it to find out. Turns out I dont need one, so that's $170 I can spend elsewhere.
I did take a few pix with the camera of junk i found in there which will get cleaned out when I pull the upper cowl panel. Looks like still pix from inside a shipwreck on a deep sea diving expedition. Heres a peak at some hidden treasure mateys. How many items can you identify?
