The port in picture #1 goes to the brake booster. There should also be a
check valve there. The part on the manifold in picture #2 is the EGR
valve. A pipe connects there, goes to a filter/cooler under the left
side tin, (which is missing), and then connects to the exhaust system.
Proper functioning of the EGR system is extremely critical for these
engines as it lowers the peak flame temperatures thus reducing both NOx
and burned valves and heads. That valve thing with the 2 big hoses is
the "deceleration" valve. Its purpose is to slightly bypass the throttle
when decelerating with the throttle close. This ensures adequate air for
combustion. The water cooled vans eliminated the need for this by simply
turning the injectors off during closed throttle decel. One hose goes to
the air intake boot and the other goes to a tee connection on the
auxiliary air regulator.

Hope this helps!
Dennis

Ok, two questions on a 82 Vanagon with a 2.0L Type 4 engine I'm piecing
back together (I was given the van.)

1.      What am I missing in these two pictures:

The area is circled.  Something defiantly connects to this.  I think it
connects to the hose circled in green on the second picture as this hose
goes no where.

The red circle  - something looks like it's just missing.

2.      I have put back on a piston and 2 jugs and the head etc.  With
the coil disconnected and the dist cap off, I tried to crank the engine
to get oil in the case (get the oil light to go off.)  But when I do,
The starter goes CLONK but doesn't turn the engine over.  The battery is
good, even tried a different battery and tried it with my 50A quick
charger connected and on.  Voltage on the battery is 12v and drops to
9.7v when the starter goes CLONK.  Any ideas here?

Thank You!
