|dsire, I'm curious what you think of the throttle body cleaner spray technique. Also any ideas of how to clean upstream of the intake manifold and downstream of MAF? Is it even that big of a deal to clean that section? (obviously not compared to valves, etc. I just mean is it worth the effort to clean that section)
Also, do you think an atmospheric catch can pcv system would adequately evacuate gases from the crankcase or do they have to be evacuated under vacuum like from a vacuum pump or slash-cut system (assuming the line to the intake is not used any more)? I'm still looking for an adequate PCV solution that eliminates the oil/contaminates coming back to the intake but uses some vacuum to adequately evacuate gasses.
Here is an example of vacuum assist catch can:
