What is the clunking sound in the front end of my olds intrigue?

Nothing good, if it is coming from inside the engine I can assure you of that. Stick your head underneath and see if the clunking is louder from underneath the engine that on top of it. If it is, it's your big end bearings that connect your piston to the crankshaft about to separate. If you are really, really lucky, it is noisy because you are down to about your last two drops of oil, and throwing in a sumpfull might save em if you have got to it quick enough, but if your oil level is normal, well it was probably time for a new car anyway.
