That's your timing belt cover.  I can't think of any reason why removing
the plug would make the engine run better; this is just a protective
cover, it doesn't seal or anything.

It's held on with a couple obvious bolts to the right side of the head and
injector pump bracket, a less obvious bolt to the left side of the head,
and a bolt down in front of the coolant overflow tank that's not obvious
at all. ;)  Be careful with that last one, it's easy to cross thread.
Been there, done that, and I curse at it every time I have to put the
cover back on. :P

The two sensors on the front of the motor are oil pressure (on the head)
and water temperature (on the heater hose nipple.)  There's also a
temperature sender for the glow plug system in the radiator hose nipple
that comes off the right side of the head.

(When I say 'front of the motor', by the way, I mean the end that points
towards the front of the van, not the end that's pointing towards you when
you're standing there.  As Muir used to say, 'Front is Front'.)
