Question about 1988 Ford Ranger
If its an ohv type the most common fault is that the oil ways to the rocker shafts become blocked
so get some flushing oil drain the oil and replace with the flushing oil and run for the time stayed on the can then Change to good quality oil and new filter
then remove the rocker covers and check and adjust the valve clearances
if its an ohc type its all hydraulic adjustment
you could try flushing as above but apart from that the only other way is to change the lifters and followers
hope this helps

I had the same problem with my 2.9 in my 88 ranger. I used some lifter medic and it helped a bit. In the end I wound up adjusting the noisy lifters. If they are just lightly ticking a good engine flush should take care of it. Noisy lifters is a common problem with these engines. Adjusting the lifters on them is not a huge job. Pull the covers and find the noisy lifter and snug it till yoy hear a really light tick. There will always be a very slight noise but that is nothing to worry about. Dont overtighten or the engine will lose compression and burn valves.
