I have had no one give me any idea on how to set the timing on my 1984 vanagon 1.9L on my first post ....anyone have advice?
I've got a '84 GL and I use a timing light and dwell/tach/voltmeter to set
rpms and the timing per the Bentley Manual. If you don't have all three,
time to get 'em.
For our 1.9's with digijet, Bentley calls for rpms to be 850 + or - 50 and
timing to be 5 + or - 1 degree ATDC (After Top Dead Center).
Your crank pulley closest to the engine will have two grooves in it 5 degrees apart.
The first one is U-shaped, TDC, the second is V-shaped; That's your timing
mark. Put a dab of white paint on the timing mark so it'll show up under you
Unplug the two wires going into your Idle Stabilizer, the
little green box on the wall to the left of the engine. Plug those two wires
Hook up your timing light and loosen the 10mm bolt cinching the
base of the distributor.
Start her up, let her warm up a couple minutes and
set your rpms using your tach set and the Idle Adjustment screw on the
Throttle Body. Clockwise, faster, counterclockwise, slower.
After you've got
the idle speed right, use your timing light on the ATDC mark to line it up
with the passenger side of the tab with the hole in it sticking out of the
engine casing. Get the rpms and the timing balanced, stop the engine, put
the plugs back in the Idle Stabilizer, tighten down the distributor and have
