Anyone have a write up on Rocker Arm replacement?

[6.4 Stroker]

Usually they have ticking or a typewriter noise.

Meaning you need to pull the valve covers and look. No other signs ?

aside from sound, you will need to yank a cover

How do you know when the rockers need replacing ? My truck is approaching 200K.

like others have said, itll make a funky sound, but ill be willing to bet with close to 200k yours will be worn out.

It's not a bad job at all, like already said getting to them is the worst part. There is a torque process you need to follow. You have to turn the crank dowl to the 10:30 position, look at cylinder 3 and 8, to see which intake valve is seeing lift. According to what stroke the engine is on you torque down 4 cylinders, then rotate the engine and adjust the remaining 4. I can't remember off top of my head what 4 cylinders go with what valve. If you can't find it pm me and I will email it to you.

If number 3 intake shows lift tighten 1,2,7,8 To 45 ft/lbs with the upper/inboard bolt first. Then rotate the engine 360 degrees and then torque 3,4,5,6 using the same procedure.
