Yeah, it's really hard to justify paying a shop to do most things on a vehicle if you have a few hours and a toolbox...
YouTube has made it so much easier - annoying though I find it (seriously, just give me a repair manual and leave me alone) to watch videos, the amount of free vehicle repair information out there is utterly insane. Unless you drive something really weird, someone has probably done a video talking about exactly what you're about to launch into.
Great to see you took that on. :) It just keeps going, and sooner or later, you find an engine in pieces being rebuilt in your basement.
