Got my Quaife and ETS FMIC installed this weekend! I will be getting my JB4 in the mail tonight and installing it as well as an RB PCV valve to address the blowby I'm getting. The stock downtube to the FMIC had pooled oil in it- not a lot, but it's there. I was concerned that my oil consumption rate was caused by a leak bc some member here aid it was just too high to be consumption, but VAC motorsports assured me after looking at my car that there's no leak and my consumption rate is within the realm of normal N54 behavior- and is probably due to a weak PCV.
I might also get a BMS OCC, but I will do the PCV and test for a month first.
