[s-cars] T-belt service question - specifically the cam pulley

[Sean Douglas]

I just went through this on my 90q20v. Yes, as long as the t-belt is still 
attached and tensioned, you can rotate the crank and install the crank lock. 
Use a 24 mm socket (I think) and with a quick flick, loosen the cam bolt, but 
do NOT remove it, it will put a little strain on the t-belt, but not enough to 
damage it. Loosen the crank pulley bolt (27 mm) with breaker bar, but do NOT 
remove. Remove crank lock tool and line up timing marks.

Now you can remove the cam pulley and crank pulley (harmonic balancer). While 
you have the cam pulley off, change the seal and now is the time to replace 
the cam position sensor as insurance.
