Default Ticking noise from engine

1990 oldsmobile eighty eight royale

For since i have had my car, its made a ticking noise from the eingie. It really quite annoying and ive never been able to figure it out. I dont think its a big problem since its been running fine all the time but its just an irritant.
Take a look at these videos and you will see what im talking about.

Idleing: http://media.putfile.com/Idle88
Shutting off, it makes a weird noise, like a cough: http://media.putfile.com/Growl16

General Info:
-Noise is coming from the back of the engine(the end near the cabin)
-Catalytic converter rattled last year but doesn't anymore, even if i hit it meaning that it all probally broke up and went out the back
-I opened the cap where you fill the oil while it was running and can tell that its not coming from them.
-Gets faster as i rev the engine


ANY help or ideas are very welcome. THX


EDIT: Another video of the camera going around the engine and opening the oil cap

My 91 Bonnie does both of those in the exact same manner...

I have never been able to tell if that ticking was due to a Lifter or Valve issue... It still ticks a bit to this day... I am thinking it has something to do with the Balanceshaft bearings... I have heard the 90-91 3800'* make that same noise... The 88-89 3800 seemed to be quieter...

If I ever replace the engine it will most likely be with a 93-95 L27 Long Block

So does anyone know how to fix this or is this just normal?

This is one of those things I just don't lose sleep over. I noticed my Olds has that slight tick you described and occasionally my car will "cough". But unless your car "Shakes, Rattles and Rolls" I would just turn the radio up a little louder.

True, My friend with the 92 Park Ave( I think its a 92... Might be a 91 ) with the L27 3800 tells me every time he pulls up to a Micky D'* or the like he can hear all the ticking...

I'd say its the nature of the beast... Mine has been that way for a long time... Still drives good... I just live with it... And thats with Mobil 1 in it

Yeah, if you have an intake, that sound is most likely from the vacume that was created at idle, and you hear that final gasp after you shut the engine off.. Nothing to worry about there
