Did you use any notes, etc to follow when you did this? 8 hours under the bonnet wouldn't be a problem but a definitive list of tools, etc would be useful to get all the parts together before I started.
I used notes from this website. Itís superb:
(the notes are for a 156 put it ultimately the same)

. Jamie has some very handy hints. I bought the parts from here, fantastic service (Iíd take mine here if I lived closer).
Essential tools, cam locks, tensioner tools, cam and balancer bet tensioners. Get both. Can to balancer without one but if youíre doing it single handed you need it. I had to customise the balancer belt tensioner tool I got off ebay as the shaft was too long (air con lines were in the way. So took a hammer to it. Anyway, TDC guide and gauge (some say you donít need this, I found it essential, esp. when putting the cam belt back on). Tippex - to mark out the various sprockets as a helpful guide (found this very useful on the crankshaft sprocket as a safe guard.)
You need a 15mm deep crank (long shaft) spanner to get the air con idler off (very tight gap between bulkhead and idler).
Things that slowed me down:
Auxiliary Belt removal and replacement. Difficult to get at and took me ages to work out how to loosen tension off (itís an auto tensioner type i.e. itís spring loaded). Basically from under the car you need a 15mm spanner onto the idler bolt and pull it toward the front of the car. I got a bar on it for extra leverage. Get someone to help with this if you can esp. putting it back (remember the belt route as well, it goes all over the place).
Putting the cam bet back on and tensioning it. Tried to do this without loosening the front camshaft sprocket. Much easier when I loosened it.
Didnít take any note which bots came out of where on the cam covers. A pain getting them back. Worth marking them as there are at least 3 different lengths (schoolboy error). Remember the longest bolt is for the auxiliary belt cover.
Getting to the balancer belt tensioner bolt was a pain. You need a 10mm deep crank spanner. Very tight space between the air con compressor fixings and tensioner bracket.
