When I encountered a camshaft that was not plugged, I found it handy to remove the left side bearing housing by tapping a rod passed through the hole.
But the last time I had to remove a housing, it was very stubborn and the hole was plugged so it didn't go as nicely as I would have liked.
Now I'm wondering. If I could punch out the steel plug, then replace it with an aluminium one, that could be a good last resort to allow me to use the rod method? The plug could be drilled out and replaced afterwards.

I always remove the left hand camshaft bearing housing by removing the camshaft nut and then using the cam itself as a drift for a couple of millimeters of travel to dislodge the left side cover, so the slug in the oil way of the cam (for me) is not a problem, I never had great results using the rod through the cam method.
Cheers,

Does the rev counter drive connection restrict the flow to the bevels?

Good tip, thanks.

I’m working on a 66 Monza as well. The intake rocker was worn (now out for repair) so I suspect it was low on oil in the cam/rocker area.
Can anyone give me a procedure or so pictures link of this restriction mod so I can do it?
Thanks in advance.

Typically, the cam has a roll pin inserted in the threaded end of the cam to restrict oil. Your local hardware store hopefully has appropriate sized pins that work. If you want to completely block the oil passage to the threaded end of the cam (so all the oil is directed to the rocker arms), press an aluminum pin in the end of the cam. You can also drill a hole in the aluminum pin to restrict oil flow more than the roll pin method.

This is a bearing housing I made with an oil seal running on the end of shaft, too get 100% of the oil into the centre. The feed pipe will run direct from the main gallery at the pump, and not through the torturous path, and finally through a very hot cylinder head, as in the standard set up. I am still building the engine, so no feed back at the moment. I will make the banjo bolt at the input flange of the housing with the same bore size as the dowel at the head joint, so as not to starve the crankshaft. I don't know if this is normal practice to have a restriction when fitting an external supply ? I will also restrict the outlet bore at the drive end of the shaft.
The seal will be retained with the circlip when assembled.
