Doesn't the pulley have a shoulder on it (the reason you can't see the key
that locates it on the camshaft) so you can't put it on "backwards"? On my
'91 200q20v, the pulley had a little "o" mark on the front that didn't seem
to go with anything, but there was a line stamped into the metal of one of
the teeth that aligned with a mark on the valvecover. I seem to remember a
similar arrangement on the I5 in our 4kq where the line on the back of the
pulley lined up with the driver side corner of the valvecover gasket.
Anyway, I had to look the pulley over on the 200 very carefully in a strong
light to find the mark. On the 4kq, it was easier to spot. I find TDC by
using a piece of dowel in the front spark plug hole and turning the engine
very slowly. I mark the dowel before disassembly and then can use it to
locate TDC later.
