Re: PCV Valve Fouling my plugs and Bad Idle Quality
Well I'm gonna roll the dice at this stage. I actually ordered a ME Wagner Adjustable PCV and a catch can.
The reasoning for this is for two things. The oil drainage passages in my Brodix heads are rather small and oil can pool up towards the rear of the heads where the baffle and breather is. The distance from the baffle and the breather is probably 3/8" which in my thought process causes higher velocity of air escaping causing shooting any oil mist up and out. Now, I don't have an engine or engine bay covered in oil but I do see faint white smoke rising out of the breathers at idle.
The rings I have on my engine are Total Seal Plasma Moly. The engine it self has 235 miles on it some of those are dyno sessions, street poundings, and idle tuning time. I'm hoping the adjustable PCV paired with a separator tank will allow to better tune my idle mixture, have it run better and keep my plugs from getting oil soaked. I'm currently running 40wt Valvoline VR1 (Houston is friggin hot) with Extreme Polymers Racing Oil Additive. My pressure sits around 38-42psi fully hot (compared to 25-30psi hot with 10W30 and no additive). My bearing clearances are about .030
I'm talking to my engine builder now to see their thoughts but they state the streaking is fairly common on very low mileage assemblies.
