[Vwdiesel] More Quantum Questions?

Bill,
The tensioner was discussed on or around 18th December.  With timing belt 
off, you are able to spin it. If it's anything other than silent, then 
replace.  I think general consensus was that new tensioners generally are 
not as good as original or early replacements.  They are cheap to replace 
but once replaced and youre hooked on replacing with timing belt. At current 
prices I'd be inclined to buy one, and grease it up and store it, but not 
replace original if that was still good. [I assume that timing belt covers 
were kept on, unlike some folks who leave them off and allow ingress.

I also think your head was fine, as long as there wasn't some surface 
corrosion in one place that needs machining out. Did you keep the gasket to 
inspect and find water tracking?  Those lbft release figures for the head 
bolts seem reasonable to me. Apart from the few that were  hardish to remove 
just due to natural stiction, what I was looking for was one or 2 that only 
required say 30lb ft to undo, as a source for you water problems; if indeed 
the clamping force is the issue at all...
Hope you have found a cheap source for the belt tensioner, else it is an 
unneccessary expense.
The water pump belt comes off by the 3  [blimey or is it 4 (8~D)...] Allen 
headed bolts. Hold still using a bar wedged inbetween the bolts that you are 
not loosening, then work round. Belt tension is altered by the number of 
washers inbetween the splittable waterpump pulley, fewer for more tension so 
to speak....

Any pictures of your car available?
Mark
