I pulled the intake manifold apart to clean and install new gasket & injector seals. I found puddles of "?" in chambers that are seemingly sealed, that is, they don't open to manifold chamber or head ports directly.
I'm guessing these cambers catch/trap any excessive liquid vapor/oil carried by air from entering head through final intake port. The very dark port just to the outside of these cambers go directly into the heads intake valves cambers, fuel injectors are at the bottom of these intake manifold ports.
Just before pulling intake, I fogged with a full can od SeaFoam, spraying through DS PCV inlet of intake manifold. I then drove two ~5 miles trips, varying gears (D, 2 & 1) to get high RPM's on city street, too blow out.
What is the liquid? How did it get in there? How's it going to get out?
Puddles in cambers
Top half of intake manifold. Front: PCV inlets ports & small capped inlet tube port. Rear: Vacuum port to power steering pump sending unit.
Fuel injectors tips penetrating bottoms of intake manifold port outlets.
Old gasket.
New gasket
