NA how to: Replace your VC Gasket and CAS O-Ring

[— fwdtamiya —]

1. Should be pretty obvious, remove the spark plugs wires
2. Remove the rubber breather hoses on the left and right side of the valve cover
3. Remove the 10mm bolts holding the valve cover,



4. Remove the 12mm bolts holding the coil pack



5. There are 3 electrical connectors near the CAS you'll notice that need disconnected
6. Remove the valve cover!
7. Mark your CAS with white-out, a penil or marker, whatever works.
8. Remove these 3 bolts, or you can just loosen the yellow ones, since we're removing everything, I just prefer to...remove everything. This will give you better visibility of the tangs on the CAS you will need to re-align.



9. Once you have it out, it should be very obvious what you're replacing.



10. Put a little oil on the new O-ring if it makes you feel good and throw the CAS back in it's place.
11. Scrape all the old gasket sealant off your head. I did it carefully with a screwdriver, probably better to use something plastic though, so you don't mar any surfaces.



12. Remove the old valve cover gasket and toss the new one inside. I did not put oil on the new valve cover gasket because the directions for the vc gasket sealant I was using said it needed to be applied to a dry surface.
13. Apply some gasket sealant to hard corners on the head, there are 2 more spots near the CAS, not pictured.



14. Throw the valve cover back on, tighten bolts to 43-78 INCH-lbs in this order:



15. Bolt in the coil pack
16. Plug back in your electrical connectors near the CAS
17. Put the spark plug wires back in
