Oil Galley plugs at Camshaft

You can so that. Just tell me how that hollow bolt (which most engines never even came with) will actually get any oil to the timing set? Stop and LOOK at how it's supposed to work.

If you LOOK at it and CONSIDER what you are seeing, even Ray Charles can see its haphazard at best.

BTW and FWIW, Ray Charles is blind. And dead. And he can see how goofy that hollow bolt is.

The oul comes through the bolt and drips down... If you use the drip tab, that directs it onto the timing chain... If you don't use the drip tab, it will drip down onto the crank and the oil slinger does it's job and slings the oil around and it gets on the timing chain...

(Ray Charles told me that...)
