Question

How to stop a lifter from rattling in a 1990 ford bronco ll 2.9 V6?

Answer 1

my answer is try to check it out first on auto repair shop...,

Answer 2

There is no such thing as a mechanic in a can (a.k.a seafoam). Pull the valve cover and tighten the rocker arm nut or bolt to 20 ft/lbs and hope it's quiet. Seafoam may or may not make the noise go away but it still does not fix the problem.  

Answer 3

It maybe time to change out the lifters, or readjust the valves.  Purchase a can of Seafoam.  It is a little pricey but the stuff works great.  Any auto parts store will have it.  It has been a while since I have used it, but you pour the contents into the oil, and let it run.  It will usually take care of a noisy lifter.
