Having calmed down a bit, there was some useful content in that DIY. Imagine we had none of that stuff. The Haynes manuals are weak. With my E30 I at least had the Bentley manual.
I found the bolt he referred to. When I first took it off, I'm thinking this must be it. There was a cavity in the center of it, so as to accomodate that screwdriver looking thing.
But I couldn't see anything in the hole with my inspection mirror. Then I looked at his photos again and got a better idea of what he was showing, I took the bolt off again and managed to see the small tab in question. It's not as well centered on mine as on his. Not sure what the upshot of that would be.
I took the valve cover off and THAT is one impressive looking camshaft. Like sculpture. I found the timing mark and oddly enough, I was very close to where I needed to be. And neither lobe was suppressing a valve.
