Rover V8 rocker shaft orientation with pushrod lubrication

[cinquecento]

I'm thinking of improving the rocker lubrication by rotating the rocker shafts 180 degrees..

Normally oil comes out under pressure via the lower rocker shaft hole situated at the load side of the rocker...at abt 4 o'clock on the drivers side rocker shaft.

With pushrod lubrication, oil come out of a hole in the yella terra roller rocker which is a lot higher (2 o'clock)..away from the loaded side...and the original oil feed hole is an oil escape hole..right on the loaded side where max lubrication is needed.

Rotating the shaft 180 gives the oil film full contact with the rocker..I can grub screw the original oil hole which is now at on the unloaded side.

Any thoughts......thanks in advance

Be an idea to run that past yella terra & get their thoughts as I expect they've designed them to work with the normal orientation.

"fixing" a perceived problem that's never been a problem ?

I'm sure I read somewhere that if you use hollow pushrods then you need to block the normal rocker shaft oil feed holes..

Thanks...

That's exactly what I ended up doing. Tapped a M6 thread, thread locked grubs screws and added extra chemical steel to the theads from inside the shafts having firstly removed the end core plugs.

I installed the shafts in the standard orientaion.

Take it that was the advice from Yella Terra?

Yes, luckily I'm in Australia, so YT support is local.
