Question about 1997 Mitsubishi Galant
This car has hydraulic self-adjusting lifters - there is no mechanical adjustment. Go to the local parts store and get a can of Seafoam - pour half the can in the oil, drive 30-40 miles, and change the oil and filter. It's possible that oil sludge is preventing a lifter from pumping up. Seafoam is good at clearing that stuff out.

This car has hydraulic lifters( tappets} therefore should not adjustment, you probably have a bad or weak lifter. But, in any case you have to remove the valve covers to make the adjustment. You will see the adjustable bolt on the rocker arm. rotate the engine until the valve is all the way to the top, [no tension on the valve spring] then place a feeler Gage in between the rocker arm and the valve stem, adjust the rocker arm until the feeler Gage is snug but not tight. Do this with each valve. Check the book for the correct Gage to use but I think it is a .018.
