How many guys runs a PCV on their boats? I have HUGE oil consumption on mine. Was reading up on it on LS1 Tech and the LS motor have an inherent problem with sucking oil through the PCV in high RPM use. Most of the dudes with drag cars either run a catch can on the PCV, or delete it all together and just run a breather. At WOT there is no vacuum to pull on the PCV anyhow. Checked my plugs, black as all get up with soot..

Can't run a breather and PVC because the computer regulates all air coming into  the motor. If it's running PCV, that air is passed thru the MAF and registered, air sucked into the intake through a breather is not. Big computer problems with that scenario.
