I stuck a 2.9L out of a 1990 BroncoII into my 88 ranger.. it had adjustable rockers..i've never seen a 2.9L with non adjustable rockers..must have been something Ford did on the very last of the 2.9's...mine ran very good and quiet for a while.. no noise at idle and maybe a little at higher RPM's..the ticking has been getting progressively worse..it now ticks at any speed..i always keep the oil changed in it, so the lifters shouldn't been sludged up, i also replaced the oil pump and screen before i stuck the engine into my Ranger the engine was clean inside..should've had the cam bearings done before i stuck it in the truck..
