Put a $25 catch can on my 2016 GTI and the intake valves still gunked up at 40k
I bought into the whole carbon buildup fix for my direct injection motor and installed a catch can at 28,000 miles, thinking it would keep the valves clean. Pulled the intake manifold last weekend in my garage in Akron and the valves looked about as caked as everyone else's at 40k, so the can clearly only slows one part of the problem. Turns out the real mess comes from the PCV and EGR side, not just the breather. Anyone run a walnut blast and actually seen it hold up past 60k, or does it just come back no matter what?

Man, that's a bummer after all that work in the garage. Did you notice any difference at all in how it ran, or was it just the same old gunk either way?
