Re: WTF is wrong with this world?
But Kiwi, this is exactly the issue. A few years ago, there would be a small thread in a forum or on a wiki etc, and you'd view it, and there'd be some photo's showing you what a good valve seat looks like, what a bad one is, how to check if a valve is pocketed, another couple of shots showing pencil marks or however your tracking contact on the seats and the process, maybe a bit about making a lapping tool so it gave the correct reciprocating motion, or at least where to get one of the nasty plastic versions that last a few heads.
It was dead easy to grasp, because it was clear, concise and well, you could see.
Now, hardly anyone bothers to make pages like that, if I make up a static page detailing how I built something, there's immediately some dick saying "where's the youtube of it?" because they want spoon feeding or maybe they just fancy spaffing half a hour of their life away.
When in reality, what they were being given before was the pure information, and the chance to step up and learn a little, which when your doing simple stuff like lapping in a valve, will lead you to develop critical thinking, a eye for things and the ability to think a bit.
Throw into that mix that a staggering amount of yt engineering has massive glaring errors (look at the amount of yt "honing" videos using ball hones to try and correct out of round cylinders because the person doesn't know better) and you have the perfect crap storm forming. I realized that a few years ago when I watched some guy trying to turn his pistons for his engine undersize to fit a different block. Not only did he attempt it on a mini lathe (and fair play, you can turn out good work on even a mini lathe) but then he used a 3 jaw to chuck it in, and didnt dial the piston in. Even if he'd dialed it in correct, pistons are oval anyway to allow fo expansion around skirt near the pin bosses. The guy had thousands of likes on his video, and people posting up "oh great, I'll that too", but when I tried to mention the above was called all sorts.
so tl,dr; none of its curated, and its riddled with drivel, so you might pull off a complex job you couldnt tackle before, or you might fubar it up.
This is not a pop at people learning stuff. Everyone starts somewhere and not being a simple consumer is to be lauded. I just despair a bit at big content moneytising the niche stuff and turning it to shit with their policies.
I still watch yt, but for entertainment shows (roadkill etc). Yeah its just like switching on a tv, I know its going to be mindless scripted drivel but eyes wide open on that.
