Assessing The Problem

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.

A pressure loss test can be carried out in order to determine the extent of the problem more precisely following a compression pressure test. The leak is located by listening for sounds of escaping air.

The following areas can be checked: 

Intake manifolds (checking intake valves)

Exhaust manifolds and exhaust pipes (checking outlet valves)

Positive crankcase ventilation and oil filler neck (checking piston rings)

Coolant filler neck and spark plug bore of adjacent cylinder (checking cylinder head gasket)
