These engines have a couple of plastic pipe-hoses tucked underneath the intake manifold and behind the OFH. More and more, I'm seeing threads about these two hoses leaking. You can't remove/replace them without pulling the intake manifold (and OFH, and alternator) because they are coming out of the engine block and otherwise inaccessible.

Here's a shot of an M54 block with those two pipes still attached.
