My S65 Driver side valve cover is leaking. Previous owner replaced driver side coil pack before selling car. It a bad leak, runs down side of the block. Probably what toasted the coil pack. Has anyone did a valve cover gasket before? anything to watch out for? should start on the S65 tomorrow just looking for any and all information

Be patient and do not over torque and if you don't know the torque post your VIN

When I did my plugs at 60K I had a small leak in the back on the passenger side. Oil had dripped down on to the heat shield. Many of the bolts in the valve cover were loose. I torqued them down (as Plutoe said be careful and do not over tighten them) and have had no leaks since. I just did my plugs again at 120K and everything is clean and dry. So depending on the severity of the leak(s) it might just be loose bolts.

I ordered new bolts to do the valve cover change. After inspecting the front bolts, they were hand loose. I will replace all the valve cover bolts with new and retorque...

On your 275.980 the torque is as follows: Stage I=4Nm, Stage II=120 degrees


Don't screw things up if you don't know Stage II then google and make damn sure that the gasket is correctly placed and seated before torqueing!!

A few of my bolts were very loose as well on the passenger side. Noticed when I was swapping a bad coil pack out. I didn't have the torque specs at the time, so I just snugged each bolt down without over-torquing. I didn't want to damage the aluminum heads.

They loosen as the gasket compresses. I did mine when I was doing all the work on the car a couple months back. I had a coil pack come apart on the right side, which was unfortunate/expensive, but the valve cover gaskets weren't that bad at all.
