yet another clicking noise
all right, i've searched, BUT:
i've got the "wicked clicking" from under the hood. '92 firebird, 305TBI, it's clicking like crazy. i read about the lifters, and put CD2 (or CB2, whatever it's called) in with the new oil change, but it still does it. if it is the lifters, then is there anything else i can do to shut it up? can you put too much CD2 in?
if it's a leak in the exhaust dealy or whatever, what can i do to fix that?
keep in mind: i'm obviously a rookie in terms of engines, so go easy on me.

Clicking can drive you crazy even if there is nothing wrong with the car, you just have to know where it is coming from.
First consideration is do you have good medical insurance, are you near a hospital, can you afford a lot of time off work, and do you like pain??? Looking around the engine while it is running is VERY dangerous, especially if you are not used to it.
You need someone to watch and call 911 when you disappear into the engine, get you hand stuck between the hot manifold and the car or simply start screaming in pain.
Ideally make sure you have nothing around your neck, no loose sleeves but something tight on your arms to reduce the burn from the exhaust. I always wear safety goggles, because the fan blows painful crap into your eyes.
The main hazard is the fan and the rotating belts and pulleys.
If you are still keen to find the click, and you want to do it yourself, go buy one of those engine stethoscopes - you will use it again one day.
Start with the accessories like alternator, steering pump etc, then the injectors although they are supposed to tick, when they stop ticking, so does the engine. However if it is them, you found your tick.
Listen around the heads and where the manifold connects, and where the manifold connects to the rest of the system.
After finding nothing on top, you have to use the probe to listen to the transmission as that is turning too.
If the tick is coming from the heads, you may need to check the valve lash, which is easy, but you need the manual. Also the hard part is getting the rocker covers back on without an oil leak afterwards.
Good luck, but take the self preservation seriously
