Incorrect weight oil. Cheap or defective filter. Change the oil and use a Motorcraft or Purolator filter and the correct weight as described in your owner's manual. If this does not help, then purchase a can of Seafoam Motor Treatment. Pour it into the crankcase per the instructions on the container. If you have clogged or partially stuck lifters, this will clean them. This is an excellent product sold at Advance and many other auto parts stores. Read about it at www.seafoamsales.com I have seen 20W50 oil make the lifters go nuts; I use 10W30. The 2.3 rangers have a problem with high mileage lifter noise because the oil pickups clog from the oil pan gasket coming apart. My Ranger did that and I thought the engine was damaged, I changed the oil pickup, the noise went away and the oil pressure was a lot better, and I had no damage to the bearings.
could be a lifter sticking
it makes that clicking noise because you touch yourself at night
If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
probably just getting rocks caught in the tread.
That is lifter noise, they probably need adjusting
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
If there is a clicking noise get it to a mechanic you engine is blown and may be saved. Most likely you'll need a new one because a lifter is broken and it would be cheaper.
Stuck hydraulic lifter.

A bad resistor can cause your BCM to make a clicking sound. The clicking noise can be caused by the relays and replacing the BCM will fix the problem.
A clicking noise, when accelerating, can be caused by a worn CV joint. The CV joint can cause the axle to collapse when it breaks.
If you have a 4.0 SOHC engine you are hearing the timing chain rattle against the timing chain guides. Some slight noise is normal, but an excessive amount may mean you have timing chain guide and/or tensioner problems. If you have a 4.0 OHV engine, then you are probably hearing some lifter noise. Again, some may be normal, but excessive may be an indication of lifter troubles.
