Air Leakage In The Intake System, Checking: Check

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

Adjust the regulator to obtain a maximum pressure of 0.3 bar  (0.15 psi). There may be a gentle hissing sound from the oil filler opening. This is due to the opening of an intake valve and the leakage of cylinder pressure past the piston rings.

Check components and connections. See: Checking components .

If a leak is suspected, spray a soap solution onto the area. Check for air leakage from the canister purge (CP) valve. No leakage is permissible.
