Valve Cover Gasket Guide
 

Hi Guys,

So I changed all of my spark plugs to NGK Iridiums today. Found most of the plugs/coils were soaked in oil. I am assuming this is valve cover gasket leak? If so, are there any decent easy to follow guides out there?

Will it cause any problems if i don't have them replaced?

Thanks in advance for any input.

I just completed this job on my 4.6is last year. I used DIY posted on Pelican Parts as my tutorial and I used another but I cant recall but I do remember the Pelican parts was very detailed and lots of pics step by step

Still had it bookmarked

I also did CPS seals and vanos seals both mine were weeping but removing all the valve cover stuff made it wide open to change those 2 seals.

Most difficult part of VCG is actually uncliping fuel injector harness...

Agreed and there's a step in the tutorial I posted I wouldn't follow either

Actually was just looking around as I need to get this done on mine this spring. Thanks for the link.

Heres another link.

Guessing the first link wasnt accessible by OP so not sure helpful to those across the pond

Awesome! Thank you kindly. Out of curiosity any other items worthy of replacing during the same time? I'll probably do plugs but that's about all I can think of "while I'm at it." Think you mentioned CPS seals and Vanos above.

Thanks for the links, what are CPS seals?

Correct real easy access with all that junk off I also swapped out the plug boots too at $5ea it was a no brainer. Oh and I swapped all rubber grommets on valve covers even on appearance panel covers and the gaskets for that too. I only have 49k on mine and couldnt think of anything else to swap while in there but I did check all hoses etc they were fine. I swapped out coolant recovery tank too since I had to remove that and hard line off tank as I broke that.
