94 Excell, valve tap
My daughters 94 excell (42,000 miles) has a valve that started tapping
today. (fairly loud) All fluids are normal. It runs great. I'm going to
remove the valve cover and start adjusting the valves. Is this O.K.? Is
there something I should know before doing this.

If it's one valve and it's fairly loud, it may be a broken valve spring.
I've had that happen on a couple of cars, so make sure you check carefully.

Re: 94 Excell, valve tap
If you're comfortable adjusting valves, there's absolutely nothing you
won't expect there.
In some cases, one of the bolts holding a rocker shaft down comes loose.
The rocker shafts sometimes break. The threads in the hole are sometimes
damaged. I've had to replace many rocker shafts and helicoil several
heads.

That was EXACTLY what it was. The rocker shaft was loose on one side. I
tightened the bolt and all is well. Of course I had already commenced on
readjusting the valves before I noticed the loose bolt. I got away cheap
this time.
