Some Heroes Don't Wear Capes - They Just Stop Blow-by
The direct-injected and turbocharged 2.0L Hurricane engine found in the 2018+ Jeep Wrangler JL is the most advanced engine ever fitted to a Wrangler. But, despite all the high-tech features that make the Hurricane great, it’s still vulnerable to a very low-tech problem: blow-by. Blow-by becomes an issue with direct-injected engines when it passes the intake valves. Without fuel spraying over the valve, there’s nothing to wash off the blow-by and heat from combustion and eventually causes it to build up as carbon on the back of the intake valves. That carbon buildup prevents valves from closing fully and disrupts airflow. The result is poor running, misfires, and if left long enough, engine damage. The best solution to the problem of blow-by buildup is complete prevention. Instead of letting blow-by enter the intake, the Mishimoto 2018+ Jeep Wrangler JL 2.0L direct-fit baffled oil catch can kit
saves the day by diverting it away from the intake valves and into a 7.5 oz catch can.
