push rod question

[melmount]

Should there always be pressure on the push rod? i have had my valve covers off several times and i am wondering if any of the push rods should be loose? i am referring to the ones that the valve is totally closed so no real pressure on the push rods. Should the lifters keep it tight? Not sloppy loose but some play?

The hydraulic lifer fills up with oil pressure and holds all the play out of the lifter, push rod, and rocker arm. Depending on how good of shape your lifters are in, will depend on how much of that oil pressure is retained, hence how tight the push rod will be. If you can twist it, ok, if you can move it up and down, then you might have a problem.

Thanks

I have an 05 f250 that just had headgaskets done and when they had apart my push rods were a little bent mechanic said to replace them.
