More new owner questions

I got a great deal on a '93 with a clean carfax record but unknown
maintenance history (and it was such a good deal I wasn't concerned about
this). I'm planning some major PM, and have a few questions:

I'm planning on changing the timing belt (the car's got 108,000 and I don't
know if it's ever been changed). Any recommendations on what else ought to
be done while I have it apart?

Recently, I've noticed that the battery light will come on, and after awhile
go off. Alternator belt is in good shape and tensioned properly. What else
should I look at?

I just barely failed the NOx emissions test. I was planning on replacing
plugs and filters this weekend anyway - any other suggestions that could
improve my chances?

Thanks in advance!

The alternator brushes may be worn.

At the mileage you mention, the timing belt should be checked and most
likely changed. Along with the belt, the tensioner and idler should be
checkd for bearing wear, and replaced if needed. The water pump is also
considered to be a likely canidate for replacement. (Since everything gets
taken out of the way to change the timing belt.)

Other items are the camshaft seals. These are usually skipped on the first
timing belt change. (If it was even done.)

The crankshaft seal is a good candidate for replacement as well.

On the NOx problem, check your timing, many people advance from factory 10
degrees btdc to 14 btdc (some even go to 18), this increases internal temps
and NOx emissions pretty drasticlly. If when you check it, it's already at
10 degrees, you could hedge your bet with a temporary de-tuning to 8 or 9
degrees. It'll run like a dog but it's only temporary. Definetly go to 14
after test and use higher octane fuel if you start to hear any pinging
(detonation) in hot weather.

Good luck,
