Does anyone know where I can find a step by step instruction to replace Valve Cover Gasket? I need to replace both the Valve cover and Oil Pan Gasket.

Thanks

 

The RAVE. If you have a Land Rover, and do any work on it yourself, it is something you need to have.

Let me see if I can remember the steps off the top of my head.

1:Remove intake

2:Remove vacuum hoses. Don't forget how they go back, colored stickers are helpful.

3:Unhook and move coolant lines/throttle body sensor/purge valve/valve cover breather hoses/whatever else I'm probably forgetting. You'll also need to Unhook the secondary air injection from the sides of the intake manifold and just pull them back so they're off of their bolts.

4:Begin unbolting intake manifold. There are the obvious bolts on top, then there is one down low in the front and one down low in the back. You will also have to unbolting the plate that the coils are mounted to on the back.

5:Now you're ready to pull the upper intake manifold/throttle body out in one piece. You will need a new plenum gasket when you reinstall.

6:Finally, you can now unbolt and yank out your valve covers. It's as simple as that.

While you're in there, be sure to replace your spark plugs, wires, and coils so you don't have to do all this again to get to your coils and plug wires. You'll have to check with the RAVE or someone here will have to tell you how much to torque what because I don't remember off the top of my head.

I don't imagine the oil pan will be too difficult, though I can't say for sure because I've never removed it.

Have your head gaskets ever been done? I mean, you're half way there by this point. It's just a matter of removing the front accessories, lower intake, and heads at that point, then having the heads machined before you reinstall. If it's never been done then I'd do that at the same time.

 

For leaks, You might get away with just tightening the valve covers.
More times than not, just need to tighten the easy access lower outside ones

 

I already tried that couple of times. I think it's time to replace them. Does not sound too complicated. I will tackle it in few week.

Thanks

 

When I replaced mine the other week, I ran a thin coat of black RTV on both sides of the gasket and let it set for a few minutes before reassembly. I also used some Locktite on the valve cover bolts.

 

^Local mechanic told me to do the thin layer of RTV/The Right Stuff. Most shops don't do it because it takes extra time, but it has worked great for me.

 

THIN is the key word. Nothing more than a skim coat really. When you go to tighten the hold down bolts, you don't want excessive RTV to be squeezed out, or into the internals of the valvetrain.

 

THIN is the key word x2 as thin as gasket cement

 

Folks, this post was from last year. I will update you guys on my Valve cover gasket after one year. It's leaking again.

I think Mistake #1
I used the yellow snot (3M) type Gasket adhesive on the gasket instead of something softer that takes time to shape.

I will have to redo the gasket again but not sure how I am going to remove that yellow stuff from the surface, Bummer!
