My "Pushrod" thread morphed into a discussion about possible lubrication problems at the rocker shafts. As I noted in that post, I ran the engine just tooling around for about 5 years. It was quite "Clackity". I now know why. Shafts worn bad, rockers worn bad and a few pushrod cups worn bad.
Here are my findings so far...
See the pics, they show the wear on the shafts and two of the rockers. Note the raised dimple created on the inside of the rocker bores.
The oil line from the block to the passageway to the head seems clear. I ran fluid through it in the parts washer and fluid flowed freely right away. No restriction noted.
I blew some brake parts cleaner through the passage way in the head and it flowed right out. No restriction noted.
The oil tube is pinched. From what I've read that's an "after factory" modification to force more oil into the rocker shafts. I did note that the pinch does not stop flow. I could blow right through it.
So, my questions are...
1. Will running the oil pump with a drill be adequate to determine if oil is flowing up to the head?
Was planning on running the pump without the oil tube in the side cover to see if there is oil at the tube, then through the tube into the oil tube (without the rocker shafts in place) and finally with the rockers and shafts installed to see if oil is present.
2. If there is no oil to the tube fitting in the side cover, how do I determine the restriction down in the block?
