This is all good info. Is anyone here running more than 1 breather filter on their PCV/crankcase vent hose? We ran into issues after tuning closed loop then going to open loop so I had to take it apart and look. Found that my 5/8 hose leading to crankcase vent was kinked trying to make the bend, so I put in a 3/4” brass elbow. Also cleaned and calibrated my wideband O2 (not yet wired to ecu) and downstreamo2 but don’t think that’s causing the issue.
Seb sent me this
“Since you have breather filters on the larger 5\8 VC ports I suggest you put the PCVs on breather filters as well. One thing that occurs is since you have breather filters on the larger ports you've essentially created a vac leak with the intake manifold going to the PCVs.“
Any idea where he’s thinking? The only place i can think is putting another T and a filter right at the PCV valve.
