I did my timing belt/waterpump over the weekend and the marks did line
up. I didn't check cam lobes, or piston position, but the '0' mark on
the flywheel coincided with the dimple on the cam gear.
BTW, the manuals say the dimple on the cam gear should be level with
the top of the cam cover gasket. As I did this check with the cam
cover still in place, I estimated the top of the gasket to be 1mm
lower than the top of the lip of the cam cover.
As far as I could make out, all marks were aligned to within 1/4 of a tooth.
Somebody was enquiring a couple of days ago about whether tool 2084 was
necessary. I asked this some time ago and got the following responses
a) Buy the tool.
b) Use a BIG screwdriver in the flywheel teeth through the timing
c) Remove starter motor and wedge something in the flywheel teeth.
d) Remove sparkplug, lock up engine by filling cylinder with nylon rope
(I didn't know whether this was serious or not, I had visions of
popping the cylinder head)
I was too mean for a), too lazy for c), and too frightened of d). That
left b). In my case, the bolt had already come loose, so all I had to
do was tighten it. I locked the engine with a BIG screwdriver through
the timing inspection hole. My wife put all her weight on a 3'
extension. Naturally, I won't say how much she weighs, but I estimate
she was exerting getting on for 450ftlb! I managed to hang on to the
screwdriver in the flywheel (only just), but I dont't know if I could
cope with undoing the bolt using a similar technique.
