misalligned timing belt

[kbogach]

Hi Listers,

I would appreciate if someone had the following problem and/or know at 
least one possible reason for it:

On MC2 engine, after timing belt job (note: new roller and water pump) 
the timing belt (right one, for MC2, aka super torque)  tends to 
position partially off the cam (less) and WP (more) sprockets.  About 
1/4 of belt's width is hanging off the WP's sprocket.   After manually 
centering the belt on both sprockets, spinning the engine makes the belt 
go off the sprocket's centers.   My guess is:

a)  misaligned roller inside the cast housing(boss)  (hard to imagine 
that it can go in misaligned, it is so tight fitting);
b)  misaligned WP due to dislocated gasket;

Any comments will be greatly appreciated. 
Anyone machined WP's gasket groove for thicker gasket?  How much it can 
cost in a machine shop?   The surface on block is pitted and I have to 
use hight temp silicon gasket goop.  Last time it held 2 years only.


Also,  last several month 200tq (MC2)  gives short loud squeal when 
started.  Something like foam can do if rubbed against window pain.   
All belts  are new and and tight.   One of the shaft seals?  Oh... no...

Thank you and Happy New Year to everyone.
