I've got a 2015 Jeep Wrangler JK with the 3.6 Pentastar. I've noticed a burning oil smell when I stop after driving, and sometimes a little smoke comes from under the hood. I looked underneath and saw oil dripping onto the exhaust manifold from above. A friend said it could be the valve cover gasket, which is common on these engines. I need to find a shop that offers Premium Leak Detection Abu Dhabi and can pinpoint exactly where the oil is coming from, whether it's the valve cover, the oil filter housing, or the oil cooler. Has anyone here had an oil leak on the Pentastar that drips onto the exhaust and found it was the oil filter housing? Also wondering if a leaking rear main seal could drip there. The car has 110k km and the leak is getting worse. Any advice on what to check first or a good leak specialist in Abu Dhabi would be great. Thanks.
Valve cover gasket on the 3.6 Pentastar at 110k km is the most common source of oil dripping onto the exhaust manifold and producing exactly the burning smell and smoke you're describing. It's a targeted fix that most Pentastar specialists have done many times.
Oil filter housing gasket on the Pentastar is actually a more common leak source than most people expect at this mileage and sits in a position where the oil runs directly down toward the exhaust. Worth adding to the inspection list alongside the valve cover.
UV dye leak detection after cleaning the engine properly is the correct approach before assuming it's the valve cover. Oil that has been dripping and spreading makes the actual source hard to identify visually without tracing it back with dye under UV light.
Rear main seal leaking would typically drip toward the transmission bell housing area rather than onto the exhaust manifold. The front of the engine drip pattern you're describing points much more strongly toward valve cover or oil filter housing as the source.
Getting worse at 110k km with burning smell and smoke under the hood is genuinely urgent in UAE summer heat. Oil dripping onto a hot exhaust manifold is a fire risk that makes this worth prioritizing over other maintenance items regardless of how slow the leak currently seems.
