Garage came out really nice. I ran my AC and coolant lines in a similar matter. Yours came out cleaner than mine. A mechanic friend recommended I run an oil catch can in the PCV system. GM is having a problem with the direct injection. The valves are not sealing with increased mileage. With no fuel flowing over the valves, and only oil vapor from the PCV system. The valves get gummed up and can’t be cleaned. I was shock how much oil mine catches. Just thought I’d pass that along.
