Question about 1994 Mitsubishi 3000GT
A tapping sound could be lifter tick, or rod knock... if it goes away, what you have is lifter tick, check your oil, low oil makes it worse.
Oil pumps up the hydraulic lash adjusters in your valve covers, at lower RPMs, the oil pressure is lower and will not fully pressurize them. Try holding your rpm at about 3500 or so with the car in neutral (parked) and see if it goes away, it should.
In later years (I think starting in 97 or so) mitsu started using a larger bore so called "third gen" lash adjuster. They don't tick as much, but they still do at times.
The good news, lash adjusters are not THAT hard to replace, figure a set of 24 will run you less than 150 in parts.
The better news, it doesn't hurt anything, as long as you can live with the sound, there isn't any reason to change them.
