Valve Cover Gasket Replacement

Greetings fellow Crown Viccers,
I am about to undertake changing my valve cover gaskets. Yay! I'm so excited! (can you smell the sarcasm?) I'm reading up on how to do it in my Haynes Manual. It tells me to remove the left DIS module in order to provide enough clearance to remove the cover. Sometimes these books add extra steps. Is this one of them? If not, what is a DIS module? I don't have a clue what it looks like. And for a first time "valve cover gasket changer", seriously, how hard is it?
Also, how hard is it to change the intake manifold? I may need to do that too.
Thank you in advance,
Mark

Re: Valve Cover Gasket Replacement

Your book probably covers a lot of years. This is what you need to remove the valve covers in the first part of the repair. | Repair Guides | Engine Mechanical Components | Rocker Arms | AutoZone.com. Here's the way to remove the intake manifold. | Repair Guides | Engine Mechanical Components | Intake Manifold | AutoZone.com

Bert, yes it covers over a decade of Vics.
Wow, that seems like A LOT of removing sh*t!

Yeah, it was on my truck, too. If you haven't bought the gaskets, yet, try to avoid the cork, the silicon is more forgiving.

Re: Valve Cover Gasket Replacement

Don't forget to also replace the grommets around the bolts. They are often the source of leaks and are much easier to replace with the valve/cam cover removed.

I didn't catch the year model of your car, but only early year cars had the DIS (wasted spark) modules. They are easily identified as they are bolted to the front of the cylinder heads and have the plug wires running from them. If you have a COP (coil on plug) car, you will not have DIS modules.

When removing the intake manifold, the 10 mm bolts holding the EGR valve are difficult to access on early cars. I have found that it is easier to remove the EGR valve with the manifold and it is easier to unbolt the EGR tube from the exhaust manifold end. The EGR is much easier to access on later models.
