    Just got to pop open the SpeedLogix catch can I put on the "new to me" SRT8.
    I have only put on 4K since my first oil change, but was curious.
    I've already got about a quarter cup of blow-by.
    Thanks goodness that is was all pretty thin; no Sludge clumps like my V6 had.

    It's a good thing that you installed an oil catch can on your 6.4. I have a Billet Technology oil catch can on my 6.1 2009 SRT. Here is the reason why.

    Some think that the absence of a catch can will result in damage to your engine. That is not the case. The issue is engine efficiency. It prevents a build up of oil residue that can result in a loss of power to your engine, over time, due to PCM-pulled timing.

    During normal operation, a small amount of that ignited air/fuel mixture leaks past the piston rings and ends up in the crankcase. This leakage is called “blow-by” (leakage past the piston rings), as well as oil mist. Some of the oil mist and other products settle along the engine intake and over time form a “gunk.”

    The oil catch can collects the oil mist and condenses the fuel vapors while allowing “cleaner” gases to be passed back into the intake. The OEM system does a great job of meeting emission standards and removing the harmful contaminants, but the unintended consequences are the oil that is drawn into the intake charge. For an engine to produce the maximum amount of energy per explosion (of the A/F in the combustion chamber) you want air & fuel only- any amount of oil in this mix will hamper the explosion resulting in less energy released, detonation, and carbon buildup.

    Trapping and removing this oil before it gets into the combustion chamber is the only solution to maintain maximum engine efficiency and prevent excessive carbon buildup. (Note- This is especially critical on turbo cars).

    Catch Can

    I posted my thoughts and experiences as a guy who had a V6 Challenger with a lot of sludgy blow-by...AND HAD A BLOWN CYLINDER before I put the catch can on it! And that 2010 V6 engine was well documented to have big blow by problem.

    Sometimes experience and real life usage transcends the engineering.
    Just my 2 centavos!

    My 6.4L is only a month old, but I want to keep her running in top shape. I checked out BT and I will definitely buy mine from them. :D
