piston ring seal or rering

sound like i may have to try that bon ami stuff, where i can i find it? my 99 ram never burned any oil, then after i changed the heads and intake (ported another pair of heads and but new valve seals in em and lapped the valve, and did the kegger mod on the intake) and now it burns oil, not too bad but is annoying having to keep checking the oil. also it says to dump a lil bon ami down the carb, but my ram is direct port fuel injection, would it work by putting it in the throttle body or would it just sit in the bottom of the keg intake?
