Jeep Wrangler engine smoking after 30 minutes of driving with 150 pounds compression test result on Jeep Wrangler

Some Jeep Wrangler owners report experiencing engine smoking after 30 minutes of driving, which may be attributed to several potential issues. One common cause is leaking valve covers, where oil seeps onto the exhaust, resulting in visible smoke. Additionally, some owners notice blue smoke, which typically indicates an oil-related problem, such as leaking valve seals. If the smoke emits a sweet celery smell, it could suggest coolant burning, pointing to a possible coolant leak into the engine. Although a compression test result of 150 pounds is generally considered normal and indicates that internal components like piston rings and valves are functioning properly, it remains crucial for owners to inspect the valve covers for leaks, check for coolant leaks, and monitor the smoke's characteristics to accurately identify the underlying cause of the smoking engine.
