Ill try to step if up to 40w. Its the stock boost controller with all the vacuum lines and pill in. After I pulled the intake tube the first time I drove it for a day and had a massive oil leak from what looks like the intake tube going into the turbo. Mid way down the intake tube where the flex wrinkles are there is a lot of oil soaking and the tip where it connects to the turbo is very oil logged. I checked the PCV valve and it was clean and rattled freely (I brake cleaned it anyways just to make sure it wasn't clogged)
I am totally stumped with this car, I can't figure out whats going on with it. I was thinking my lack of boost could be from oil being sucked into the boost control valve from the intake tube maybe? At this point I'm totally lost on this thing.
EDIT: Uncle Scotty 10w30. The cap calls for 5w30, should I be using 10w40?
