hi, ive got a 91 brat pickup and was goin to adjust the valves,but how do i tell which variety of lifters i have, solid or hydralic? as i understand it,hydraulic lifters need no adjustment.cheers

in less the engine has been swapped out It should be hydro

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....

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.
