I've been excited to follow up with you guys here, but, well, life. The mod worked well as it always does! The coiled fuel line complimented the groove very well. I put 5ml snake oil into the oil, drove it once today and was in a rush with the kids but I'm feeling very confident that it's doing its job because I'm positively impressed with the reports I'm seeing, and worked amazing in our 07' focus 2.0L. I spoke to a GM mechanic at the forest lake, MN dealership about the pcv location. He pulled up a diagram and said it doesn't require having one, only the crankcase breather hose. I asked "if this engine doesn't need a pcv, then why put them on other ones?" He replied "it's an old design, so it doesn't make sense" You see, it's not that complicated. If you see something that doesn't quite make sense why it's there, it's usually an INEFFICIENCY. God bless that simple minded mechanic!
