First time poster. I am in the middle of replacing the original engine and
transmission in my 1991 Vanagon.  This is after long thought on putting a
Subaru motor, however for cost reasons mostly I'm sticking with all VW for
the next couple years.

So far I've pulled both my engine and transmission out. I have a rebuilt
transmission from Daryl at AA Transaxle( the core will be returned shortly!
if you're reading Daryl)  I am waiting for my rebuilt engine to arrive.

Things I have decided to replace while doing this.
Fuel lines (all inside the engine compartment)
fuel injector seals
exhaust gasket
distributor O-ring
intake gaskets
all water hoses
clutch/pressure plate/release bearing

Things i'm considering
rebuilt injectors
throttle body
O2 sensor
Cat(mine is rattling...not sure if this is normal)

Any advice on other things to inspect/replace NOW while everything is out of
the van?
