    on my 13 srt8 challenger my BT catch can is mounted low so the oil will flow down into the can....on my cat the can is mounted higher so the oil has to go up to go into the can....do you think that it may flow back to the valve cover without getting to the can easily?...Just wondering what your opinions are.....thanks all.....

    So long as it stays out of the intake manifold, that is the goal.

    Higher is always better and that's why NASCAR always mounts them high.

    the whole concept is the deposition of oil vapor in th can and its done by passing the vapor over the steel mesh where it collects and then drips into the can. It shouldnt make a different height wise. its not a dishwasher drain or trying to siphon the oil out

    Hi folks, given the amount of Engineering and testing employed in the development of our powertrain, please help me understand why the SRT Engineers did NOT specify a Catch Can (CC) for production intent Hellcats? I understand how the CC works but if excess oil blow by is detrimental to the SC then why no OEM CC? What am I missing here? Better yet, what did the SRT Engineers miss here? Thanks-

    I actually agree with you and am also curious about the same question. I am hesitant to add one only because I would think it would have been there from the start if it was needed. I am sure many companies make great catch cans, but is the need really there?

    The L shaped valve covers have an air/oil separator built in (labyrinth style) and differs from other modern V8 hemi valve covers. This acts as the factory catch can, however, it is maintanence free. It doesn't catch all of the oil as witnessed by an aftermarket catch can.

    Adding a catch can requires regular maintenance to empty it by the end user, something where it is riskier for it to be OEM (if not maintained, it clogs the PCV system) vs OEM acceptable risk of roughly less than 2% of oil to be injested by the engine over the 200,000mi lifespan.

    Long term, it doesn't hurt to have a catch can so long as you maintain it, and in this case, so long as the catch can lines don't collapse due to vacuum. It would be nice to see plastic lines similar to stock run on an aftermarket catch can rather than rubber.

    So 'm clear here you're stating that our engine has been tested up to 200k miles w/o an aftermarket catch can? Thanks-
