"clacking" valves?
My 2002 ES has this loud "clacking" noise coming from the valve train area then I'm just cruzing along. Not when the car is under load, just minimal throttle input. It happens most between 2 and 3K RPM. When I gas it, it goes away.

I know when your running low octane gas there is a "clacking sound" from lack of bang but it is no real problem run some supreme and see if it stops if not take it to the service dep.

I did try higher octane fuel & it was about the same. I always use 76 gas too. I did put in some 10-30 and 10-40 oil & it helped a small bit.
So the 4G94 motor has a history of this? Interesting. Cuz it sounds lousy. Sounds like a 84 Dodge Aries K car or something!
Does the Lancer have adjustable valves? Could that be an issue? My car has 20K miles.

If oil helps it out you might have a leak somewhere and the clacking sound is the product you might want to check that out, I know a friend of mine had his oil pan stripped out by jiffy lube once

my engine make the same sound..its not that loud...the valve cover isn't that thick so sound of the valves moving does make a lot of noise. mine is the loudest during a cold start when the motor oil is not moving easily cuz it is cold. i'm sure its nothing to worry about..when your car starts studdering or boging out then i'd worry.
