Coolest Oil Catch Can

The manifolds the real story. That **** builds up like tar on it, bottom of fuel injectors, valves, cakes the top of the piston etc. its more internal that's the issue once it lowers octane mixing with the air/fuel. Ever done back to back dyno's on cars with similar setups with one with and one without after a lot of miles? And other cars are a must like subis. I can eject a 1/2 quart of oil out the valve vents in a high G turn which is why its a must they run AOS and not catch cans. The oil gets piped back to the block with them so they don't run out of oil after a few laps.

PS if your FI you'll always get oil in the charge pipes, the turbo seals can't seal 100% just like piston rings. But FI I'd definiantly do it because you now have two sources of oil getting into the manifold.
