Rocker arms won't seat!!!

[Malcalmstunt]

What's up go so I disassembled my head to put valve seals in. Putting everything back together I was going to put on the rockers and they were super loose. I know they are supposed to be tight in there, how do I install them correctly?

One end sits on the valve stem and the other on the hydraulic lash adjuster.
Once you have oil pressure the lash adjusters should fill up.

You don't want the lash adjusters pumped up to start with but you do want them to have oil in them. The manual has you prime them and then bleed them down before installing.

Is it possible this is why the rockers were loose?

So how will they be snug against. They literally fall off

Do you have the cams installed yet? The cams place downward pressure on them against the valve tip, and lash adjuster.

No the cams are out of the car.

Love Jafro. Check out his other videos too, you'll learn something. Rockers just fall off with no cams in. Just took my head off this week.

I actually watched the video before I disassembled it. So when the cams are installed they'll be snug?

Some more so than others because the cam lobes will be opening the valves so the valve springs will be applying pressure. The ones where the rocker is riding on the lobe base center may be a little loose until you have oil pressure and the lash adjusters take up the lash. In no case will they be so loose as to pop off.

Okay thanks a ton man. This is my first time working with the valves, so I want to make sure I learn everything so I can know what to look out for!
