Micky:
FWIW, I replaced the whole set at 69k on my 6. My feelings were
is that it was cheap insurance, another $25 in a $2k rebuild seemed
like a nit.
One caveat: My new timing set had no markings on it to allow
correct timing of the cam. If your old set is marked, you will need
to transfer your markings to the new set. My old set had no marks.
The Bentley manual has a nice procedure on how to time the cam
with no timing marks, which I used. It was very simple and seemed
to work very well (at least in the sense that my car started easily,
so the cam must be close). I was able to easily resolve the timing
to less than 1/2 of 1 tooth on the cam gear using the Bentley
procedure.

Subject: Sanity check - timing chain replacement
Wondering what the collective wisdom here is re: replacement of timing
chain
in the following situation:
My engine is currently on a stand while the car is going through paint
work.
I've had the Timing cover off and don't see a lot of wear on either
gears.
Car has 66K miles.
But, there is approx. 1/2 inch or better play in the chain (can't find
any
specs on normal tension and measurement is by eyeball only so far) and I
have
two new gears that were purchased by PO and not installed. Last year
when I had
the 6 on the road I was having some problems maintaining exact timing
but
hadn't really isolated the problem.
I'm inclined to just go ahead and replace the gears and chain since
chain is
minimal cost and engine is already out. Any reason to not do this? It
looks
like a fairly easy and straightforward replacement, but I have been down
THAT
road too many times.
Thoughts?
