Everyone looks for the hard way to do the timing! It is really quite
simple. This is what I do:
- On the pulley side of the engine there are some timing marks. There
should be a plastic guard installed with an arrow pointing towards the crank
pulley. Get a paint marker and color in this arrow.
- On the crank pulley there is a notch, again paint this notch.
- When the notch on the pulley and the arrow is aligned you are at 0 degrees
or TDC.
- Open the licence plate hatch and point your timing light at the arrow and
pulley and set the timing this way. Very simple!
You should set it to +6 BTDC +-2 degree according to the Bentley manual.
According to all the I4 tuners out there and from my experiences you can set
it to about +10 to +12 and gain about a 5% hp / torque boost across the RPM
range. Just make sure your knock sensor is working! This can be tested by
LIGHTLY tapping on the knock sensor with the engine revved to about 2000 to
3000 RPM you should see the timing retard for a few seconds after you tap
the knock sensor.

Subject: I-4 conversion timing problem
Ran into a small problem the other day when I realized that I can't check
my ignition timing by looking at the timing marks on the flywheel. The
diesel bellhousing is located 30 degrees or so from where it is on the golf
bellhousing and does the diesel flywheel even have timing marks?! So my
connumdrum is what is the easiest way of checking the timing? I never
checked it when I put the engine in because at that point it ran fine, but
now that it is getting pretty hot outside the van seems to have developed a
hesitation on takeoff. So everyone knows it is a 1.8L Cis-e 10:1
compresson engine from a Golf GT.
Thanks,
Dave K.
