My 2012 LS3 had 19,000 miles on it when these photos were taken, Rx Catch Can was installed at 2,000 miles.
1. The throttle body has 17,000 miles on it with Rx Catch Can, there is no oil present on the throttle plate as tested by swiping my finger across it. When I removed the factory throttle body at 2,000 miles it already had oil accumulation on it and the intake manifold interior had a light coating of oil.
2. The oil catch volume is minimal at 17,000. My break-in routine was reasonably hard, about 50% throttle when accelerating to push piston rings against the cylinder bore during the first 250 miles. Miles 250 - 500 contained a number of WOT acceleration runs, with ample cool down periods to heat cycle the engine and driveline components.
3. Location of the Rx Catch Can in my LS3.
In my opinion, at minimum the Rx Catch Can will pay for itself by eliminating the cost of periodic throttle body cleaning service.
The performance benefits of maintaining ignition timing is a great benefit, too.
