We bought an ultra clean 2006 XC90 AWD V8. The car is a one owner and it appears that they kept the vehicle up quite well.

We detected an oil leak and the dealer confirmed that the valve cover gaskets are leaking. The standard time on that is about 4 hours. We decided to do the repair inhouse. The parts are pretty inexpensive and it is 95% labor.

The upper and lower intake have to come off as well as the fuel rail and injectors. Once you get the lay of the land, it is not a bad job. The one area that is a real challenge is that there are a pair of ground wires along the rear edge of the valve covers, both front and rear. The way that it is designed is that a stud clamps the valve cover down and then a grounding strap is attached to the top of the stud and then another nut holds it down. That is probably the hardest part of the entire job!

What we did is take an old 10mm wrench and ground the open end to about half the normal thickness. Then, we cut the wrench so that it is much shorter. Now, you can put the wrench under the nut on the valve cover stud and turn the top nut without tearing the ground wires off the harness!

Take my advice here. Make a tool out of an old wrench. It worked fine!
