I wish I had the knowledge skills and tools to slot a little screw like that!

Just a vise a hacksaw and a stready hand. You have to saw a curved slot as the head gets in the way..... :-)

Or even a needle file, 3 square is good (triangle).

Indeed. That would do it.

Oh my gosh. I thought you meant a machined slot.

No it's just a relatively crude way of pulling the dirt out of the thread rather than pushing it in.

I had to take the motor partially apart this afternoon. I had to in order to replace those two studs that were twisted with fouled cap nuts. Maybe the guy that messed up the cam timing thought they would look nice since he had no engine cover. Seemingly innocent little "custom" touches like that sure can mess up a motor. Splitting the case gave me a chance to look inside. I checked all the way around the gears and they look good. No chips that I can see. Notice the splotch of paint on the mainshaft. I wonder what it means.

I turned the rotating assemblies and they felt smooth and quiet with no rough spots. Here is kind of a picture with a glimps of bearing and race.

Here is the bottom half and the two studs. sI found no cracks or troublesome shards of metal.

Nice, but you did clean the parts before assembling I presume ?
It seems, or maybe it's the pictures, that a lot of dirt (spray paint ?) entered the engine ?
