I posted this under a new subject because I think it's an important find.

Rod Knock Sound On 1985-87
Ford 2.3L D (143 CID), 2.8L (171 CID) And 2.9L (177 CID) Engines

Ford Motor Company engineers advise that a rattling noise in the clutch area may be misdiagnosed as an engine rod knock. The engines listed above are found in the Ford Ranger, Bronco II and Aerostar vehicles built in 1985-87.

This noise occurs where the hydraulic clutch slave cylinder is installed in the clutch housing and can be corrected without pulling the engine or transmission. a two piece shim packet can be installed between the clutch housing and the slave cylinder as indicated in Figure 1 below. Install the shims with contact
cement by simply reaching around the clutch housing to where the slave cylinder line enters the transmission.

the shim pack is available from Ford Motor Company under part #E5TZ-7C528-A and is called Shim-Slave Cylinder.

Yes my Ranger is a '97 and I think Ford probably installed the shim pack on later models and did not make a design change, so the shim pack wears out and results in the same noise....that's mistaken for a rod knock or other serious engine sound.

Yea, for internet searches. Saved me from a major mistake!!
