Jeep Grand Cherokee WL

Most-produced FCA/Stellantis engine — used in Wrangler, Grand Cherokee, RAM, Dodge and 20+ models. Rocker arm/lifter tick is subject of a 2022 class action lawsuit. Plastic oil cooler housing leaks at high mileage — worst case mixes oil and coolant ("chocolate foam"). Dorman metal replacement as permanent fix. Change oil every 5,000 miles and react at the first tick: 200k+ miles realistic.

• !! Oil cooler housing leak from 80,000 km

  Plastic oil cooler housing leaks externally or causes oil/coolant mixing ("chocolate milkshake"). Typical from 50k miles. Dorman metal replacement (Dorman 917-114) is the permanent fix — OEM plastic part fails again.

  Symptoms: Oil loss, coolant in oil (milky), overheating, oil spots under engine
