Ive just fitted a b18c6 (ITR engine) to my eg6, the engine has been stood for like a year or more.

I also fitted a skunk2 intake mani and skunk2 thottle body at the same time as fitting the engine.

The engine is meant to be a fairly low miles engine, is it likely the valve seals are perished?

When i remove the exhaust manifold, each port is wet and oiled
