Yes I agree using the non (ball) bearing is the way to go but wouldn't this oil feed system be easier to install and cost less?

Not exact in every detail but probably meant to be based on a Magnus Walker build he brought to Jay Leno for a ride. Originally a 1971 911T. Here's the video and the car. https://www.youtube.com/watch?v=VB3JZlV6RDM

Correct. The 9A1, which was introduced in the 997.2, has no intermediate shaft. The cams and oil pump are driven off the crankshaft.
The pic at the link below is for the 9A1 in the 991.1 GT3, but the architecture is the same.

I personally think you're better off just pulling the grass seal and letting the bearing sit in the sump oil which will provide plenty of lubrication. Pressuring an oil feel line to it might cannibalize your oil pressure to the engine when you need it most, creates a point of failure on the oiling system for the engine that isn't there today, and a ball bearing isn't designed to have a pressurized oil feed which could create internal bearing resistance increasing pressure on the timing chains. Regular bearings need it because they just ride on the oil film, but ball bearings or roller bearings don't.

Just picked up my first 997 on Friday. I appreciate all the help I recieved on this forum during the shopping process. I had a 991 C2S before this - I always preferred the 997 look and feel. I'm happy with the switch.

Re: 2 pics above of your car .. what looks to be a RSR Tribute. Can you give more info on what you are showing here? Is that a temporary set of rims/tires? ..
or maybe the lift is pushing up on the car for some work you were doing?
.... looks a little out of place in that Ferrari garage. ... and my eyes are playing tricks on me with that wooden floor

This started life as a C2S. Full RSR body conversion with a few extra modifications. Wheels are correct split rims made to order to keep gearbox ratios and clearances.
If wheels were bigger they will hit the body on suspension travel and full steering lock on front. RSR has very different suspension configuration. Picture is a little obscure due to angle. Still playing with suspension set up. Might need 15mm rear spacers (max) and lowering about 1". RSR body has higher wheel arches than standard arches. Body is an original race car body from Albert Motorsport in Germany and has been a lot of work to get it to look good on a road car.
Garage - Ferrari, there is a reason. There is one in my other garage but this has the ramp so easy to work in.
Like you pointed out this is a tribute or take on an RSR not an RSR. Something a little different.

That's a sweeeeeeeeeeet garage / stable you have Petza914. Neighbors must think there is a Porsche dealer near by. Your driveway is a bit hidden from the main road, but if I had all my toys out my wife would say " go put your Porsche's back in your pants, your making the neighbors jealous"
