This is what a p.o. has done re rocker shaft oiling.It comes straight from a tee in the oil pressure switch fitting.


I am concerned that there is no restriction in the lines,
do you think i should crimp the feed line some?

Must say, it's one of the cleaner "external oil line" installations I've seen. Maybe restrict the shaft over flow tubes? That way it would "pressurize the rockers??

that is ingenious I have to say. Way better then the original ones.

Does it feed the rocker shafts or just pump oil into the area? Chuck

It feeds into the oil galleries in the block that go to the heads/rockers.
There is plenty of oil to the rockers, maybe too much and robbing the bottom end.


I will plumb a gauge into the tee and check pressure when i get it back together

If the pressure is low i will screw an "adjustment tap" into the block here,
then i will move the switch to the next oil gallery plug in front of the filter.

The problem i see with pressurising the rockers is that the timing chain
and dizzy gear then get very little oil.

Slick, do you have any pictures how "It feeds into the oil galleries in the block that go to the heads/rockers"??? Did they drill and tap into the block? That's an interesting setup for sure.

Thanks,

If you want to restrict the oil flow to the rockers you can tap the bottom of the rocker stand that feeds oil to the shaft and install a pipe plug with a hole drilled in it.I had to do that to mine when I had the camshaft oil groove deepened when I rebuilt the motor.I was getting too much oil that couldnt drain away fast enough.There should be a topic somewhere that gives the size of the hole and size of the pipe plug.It cut down the flow to just the right amount.That would work with your setup as I presume it still feeds up through the rocker shaft stand same as original.Thats a real smart setup you have.Someone intelligent thought that up.
