Jeep Cherokee XJ CCV (PCV) Upgrade

Upgrading the CCV connection from valve cover to intake manifold on 2001 Jeep XJ Cherokee Sport 4.0L. Should work on late 90's-2001. The stock setup relies on a rubber connector to a plastic tube. This goes from about 1/2" at valve cover to 3/8" at manifold. The rubber cracks (air leak) because it isn't heat resistant. I replace it with strong gas/coolant line. I did this on my own XJ but I'm not telling you what to do on your own Jeep. My goal was simply to not have to replace cracked rubber fittings every few months (success). Parts The change in diameter from valve cover to intake is accomplished with a 1/4" MIP x 3/8" barb brass connector. 1/2" Gas line & 3/8" Gas line. hose clamps Support the Channel: Venmo: DIYwithDrJeff sponsorship or enquiries: [email protected] Warning: Only professionally trained mechanics should work on autos.
