So have they solved the problem of intake valves building up crud on the back side from crankcase fumes carrying vapors coming through the PVC system. I've read of baffles now in the valve cover. Would it be worthwhile to put an aftermarket catch can in the vacuum line? This is on a 2019 5.3, now with 6K miles. Don't want to wait much longer if it is needed.
