wondering how to pull apart the roller rockers on a ef falcon :/ my last falcon basically all fell apart when i took the rollers off to change the tappets..

Do you mean to stop the HLAs (hydraulic lash adjusters, the tappers in the end if the rocker arms) falling everywhere as you lift the rocker set?

Loosen all the bolts without fully lifting the rocker set and using masking tape slip a piece between the HLA and the valve stem then wrap around and join the tape at the top of the arm.

Will take a little skill to not get the tape completely greasy and lose its stickiness.

Use the same method to install, slip out the tape before locking the set back down.
