88 90q TB job

[Andrei Kogan <abk@phy.duke.edu>]

Good afternoon everyone,

First, thanks to all who responded regarding my question about the 2084.
After thinking it over, I finally decided to buy  a used tool instead of
either making one as per "MHLIGGINS@aol.com"'s suggestion or locking the
flywheel as per the procedure posted by Phil. It is unfortunate, but this
cannot wait and I just don't have any extra time on my hands to experiment
right this moment. I have to say, making one is very tempting, especially
for me being in experimental physics group with access to a complete
machine shop etc. Oh well, time is money and vice versa. If there is
interest, I can take all the measurements of the tool when I have time  and
make drawings available, so anyone interested could make their own thing in
the future. 

Now, to my questions: 

1.
I was looking at the engine bay last night trying to picture what I would
be doing. It looks so damn tight at the front ! Could a lucky owner of a 90
Bentley tell me how they recommend going about getting to the belt. I
understand that the lower grille needs to be removed. What about the metal
(painted) piece (the one in which the holes for the hood locks are located)
that seems to overhang the area in front of the valve cover? It seems to be
in the way. 

2.
This is going to be my second TB job. When I was working on our 4k, I was
VERY paranoid (for no reason) about the possibility of accidentally
cranking the camshaft with the belt removed. Now that I have a 10.0
comression engine instead of an 8.0, I am at least as nervous :-). Can
someone tell me for certain --- is the 5cyl 10.0 engine an interference type? 

3. What is the "error margin" for aligning the cam pulley with the TDC mark
on the flywheel (is it on the flywheel?) 

4. Someone suggested replacing the water pump and the idler when the TB is
done. Can someone confirm if this engine has an idler pulley? It appeared
to me that the TB only runs on two sprockets (camshaft and crankshaft) and
the water pump. Am I wrong?

5. Are there any particularly "good" or "bad" brands for the belt?

Please let me know what I should watch out for.  This seems to be a simple
job,  but  it also appears to be the one where it is  easy to screw up big
time and blow the engine apart.

Thanks,

Andrei
