Rocker oiling
I get how you did the tubing for the rockers. I guess I don't understand the clocking of the cam bearings on 2/4. I tubbed my old block and restricted the oiling on the opposite side and didn't clock the bearings. I also ruined 2/4 main bearings with under 40 1/8th passes. The rest of the bearings looked brand new. Should I have clocked the cam bearings?
I want to block the oil from the cam up to the rockers and it has to be blocked after the cam but before the point where I installed the fitting into the gallery that feeds the rockers.
You can’t block the oil before it gets to the cam bearing or the cam bearing itself won’t get oil.
Since the oil to the rockers is fed semi directly from the main bearing, which also feeds the rod bearings and the point is to stop taking as much oil from the main bearing I don’t want to leave the oil a chance to go backwards from the feed to the rockers and the other way around.
I want the oil only able to go from the point I’m introducing it to the rockers the oil has to be blocked off somewhere after the cam bearing and before the point where the oil is now going into the gallery that feeds the rockers.
To that end, the most simple way to block the oil from the cam to the rockers is by clocking, or rotating the cam bearing so no holes in the bearing line up with any hole in the block.
The way the holes are clocked in the bearing makes it so you can’t just rotate the bearing and only have the hole from the main bearing be open and the hole to the rockers be blocked.
You make it so no holes line up, drill a new hole in the cam bearing from the main bearing.
I hope that makes sense. I’m got almost no sleep last night.
