Lifter question

So my 350 is ticking and needs the valves adjusted, but I need to know what kind of lifters are in it. Its got roller rockers, if that helps..I don't know if you have to use one kind or the other with them. Whats the easiest way to find out if what kind of lifters I have?

Was it ticking when you originally got the motor? Solid lifters have valve lash and they will tick all the time. More than likely you would only have a solid cam if it is pretty radical and your motor is capable of some high rpms. In addition if you don't know what solid lifter cam you have then you have no idea what to lash your valves to. Unless your motor is aftermarket, or someone got there hands in it, then I would have to say you have hydrolic.

is it stock motor or what? . . only way to know for sure is to pull the intake and valve cover . . take a rocker arm and push rod out and then pull the lifter and look at it . . .

ok, theres a way

listen clo.... shit. READ CAREFULLY.

take a valve cover off.

start the engine

grab a wrench that fits the adjuster nut on the rocker arm.

grab a wrench that fits the set screw inside the nut on your roller rocker arm stud

do what you gotta do to loosen the set screw.

loosen the rocker arm adjusting nut. there should be an increase in noise from this rocker arm assembly. now... tighten the nut slowly. when the noise goes away, make a mental note of "that point". turn the wrench 1/4 turn more.

now, if you have hydraulic lifters, you just adjusted one ofthem.

if you have solid lifters, you just figured out that you have solid lifters and that you have to shut the engine off to adjust them. Generally, solid lifters will work lousy as hell when you tighten the lash to the point where you have less than 0. you will get a poor first impression as the engine dies. with a cough.

carry on.
