Re: Timing belt

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 
 inspection hole.
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.
