•Warm up the engine and inspect the front of the engine block and timing cover area for any oil seepage or residue, this leak is near-universal at high mileage

•On cold start, listen carefully for startup rattle or cam gear clatter that takes more than 2-3 seconds to disappear

•Prefer 2010 or newer XV40 units, early 2006-2009 examples had unresolved idler pulley and oil cooler line issues

•Check oil cooler line connections for staining or seepage, especially on pre-2010 models

•Test drive through all gears including full highway merge to confirm smooth, prompt automatic transmission shifts with no slipping

•Pull the oil filler cap and dipstick, check for milky residue indicating coolant intrusion, and verify oil level and color are acceptable
