Nasty oil! Bad for appearances but good for keeping corrosion away!
This bolt is very hard to get to. The engine mount bracket is on the left. Access is tight. With a small 1/2” socket and thin extension is the trick. This bolt actually had a flat cut in it for a screwdriver but that wasn't necessary with 1/4" extensions.
The fuel pump runs off this camshaft in the engine block. This cam shows some wear but feels smooth.
