Straight from one of Joel's Technical Service Bulletins:
........................................................................
VW Technical Information
Group 80, Number 87-01
Date: July 31, 1987
Model(s): Water-cooled Vanagons, 1983-1985
Subject: Carpet wet by rear seat - heat exchanger bleeder screw broken
The plastic bleeder screw for the rear heat exchanger may be broken due to
seal swelling.
* Replace with an improved metal bleeder screw, Part number N 902 061 01.
and new gasket, Part number 861 819 037.
Production Change:
Metal bleeder screw installed as of:
December 1984, VIN: 25 FM 050 887
..........................................................................
The bleeder screw I replaced was made of white plastic as you described
above which is odd because your '91 should have the metal screw according
to the bulletin. Anyway, it solved my leaking auxilary heater problem
although I still smell coolant whenever I run the rear heater which had me
thinking that the core itself may have a tiny leak. I have since convinced
myself that the coolant residue left in the fiber floor board is the culprit.
