mcbrat Posted August 20, 2010 Share Posted August 20, 2010 do you have a small rectangular sticker on your valve covers? the hydro ones came with a sticker on to let you know not to adjust... of course, in nearly 20 years, lots could have happened... if you pull a valve cover off, look at where the rocker arms are attached. if hydraulic, there will be a locking tab washer on each, with the tab bent up so you can't adjust the nut....

GeneralDisorder Posted August 20, 2010 Share Posted August 20, 2010 You can also look at the push-rods themselves - hydro are steel single-peice units while the solid lifter one's have caps on the ends. GD Link to comment Share on other sites More sharing options...
