That sucks, that was a big oopsie by the Facebook ops folks. Funny enough I'm planning to interview for their production engineering team in a couple months.
Your post reminds me that I need to finally finish my project civic that I bought a few years ago. Never really set aside the time to do it all right, and haven't prioritized it lately. It's a 1990 with a b18 swap. I've gone most of the way through the head gasket replacement, just need to finish putting it together, seeing if I screwed anything up, and set the timing. Garage is currently a huge mess due to being a temporary kitchen during our remodel though, sigh. Just want to get it running again so i can sell it at a loss
