2005 Porsche Cayenne weird ticking noise been going on for acouple years have heard 3 different explanations .... Anyone ever heard of this ?
Engine off. Turn on heating blower to lowest setting. Might be a leaf of some insulation in or near the fan. Engine on. Most likely a bad or stuck hydra hydraulic lifter. Run a can of motor flush for 10-15 minutes then change the oil. Make sure you use a Porsche spec synthetic oil.
