Thank you. |
The location where the adj pcv was installed is one area that differed during actual install vice my initial design shown on the drawing. At the crankcase, there is no stock pcv valve used, just a direct connection to the AOS IN on that side, with the breather and 1psi checkvalve as failsafe should the AOS get plugged for some reason. The adj pcv is still on the same « line » but sitting « behind » the AOS vice in front of it. When connecting it directly to the engine port as initially planned, it did not reacted as well during testing and could not be calibrated properly. It also has the advantage of being protected from being plugged due to the AOS filters, and be readily accessible for making fine tuning of the idle to cruise transition screw.
As a note, I have been running the set-up for while now, with great success. I have had to tighten up (screw in) the cruise to transition screw in the adj pcv from time to time, when I felt the torque response diminishing, but that’s it. It takes litterally 30 secs to do and you can sense with the torque response right away if its right.
I found the car also performed very well with a bit lighter oil Redline 0-40 (vice RL5-40) oil for daily driving use, with essentially no oil consumption and near instant torque response, which tells me that the positive vacuum system is effective and avoid pressure buildup and oil flow issue with the turbo. When attending advanced driving clinics, RL 40WT would be used instead, however some oil consumption was seen, albeit well within expected margins I would say.
