Don't Wash the entire engine with water!! Water will get in by the plugs and cause a Missfire.
Rinse from underneath.

 

Tech, I've washed the engine and I just can't seem to find where the oil is comming from. How much oil does the S80 take? non turbo ??? I also think my shocks need to be replaced, the ride isn't as smooth as it used to be, what struts do you recommend?

 

The S80 takes about 6 Quarts.
Boge shocks should be the OEM ones.

 

you know tech, I think they have been putting more than 6 quarts in my S80. Would the car spit out the excess oil??? when i used to do it I never had problems, not until they started.

 

Check the level and see where it is at.
It might burn it.
