As far as mechanical abilities I have a brother that can machine anything out of anything. The only reason I haven't gone any further than installing a ZERK, a new gear and a good ACEA oil with high ZDDP is because I'm not having any more wear.
We can put roller bearings in these CPS units or hell we could even go nuts and pull a line off the oil pressure sender with a small orifice and make them full flow pressure lubricated. But its not going to fix the problem.
The biggest thing that needs to be realized is this isn't a normal gear cog on gear cog. What is going on is a worm gear which is nothing but a screw is SPINNING/SLIDING against the teeth of the CPS gear.
Now we add to that the resistance that it takes to spin the oil pump plus the bushing issues on the 05-06 units. That resistance is turning the spinning of the worm gear against the CPS gear to more of a GRINDING.
The only thing standing between those two gears having metal on metal contact and grinding metal off each other is a thin layer of oil.
That's why I say the oil is IMHO a primary factor for the failures and not a secondary one. Yes the bushings have their issues but I've found that even if you lubricate those bushings you still have heavy gear wear if you don't run a high quality oil with sufficient ZDDP levels.
So like I said I have a couple CPS units and a machinist that can do whatever I want to do to those CPS housings. But I'm not going to just waste his time and several CPS units if there isn't some empirical data that says doing XYZ to a CPS unit will solve the problem.
