I spent considerable time researching several forums to learn about oil catch cans specifically installed on Dodge 4.7 engines, and there aren’t many examples to find. So I decided to detail my installation to help anyone who is considering this modification.
I purchased a new PCV valve (Mopar part # 53032925AC) from Ebay and the oil catch can from Elite Engineering. The kit that I chose is the 2006+ Hemi 5.7 because it comes with ½” rubber hose and a hose barb coupler to make the connections to the PCV valve and plastic line on the 4.7 motor. The kit also comes with a short bracket to mount the catch can in the engine bay.
1. Disconnect the black rubber elbow fitting from the PCV valve which is at the rear of the driver’s side valve cover. Pull the elbow fitting from the plastic line/tube that goes to the intake. You may have to twist the fitting to break it loose before pulling it off.
2. Remove the old valve and install the new. This requires a 34mm socket.
3. Install the hose barb coupler to the smaller hole on the rubber elbow fitting that was removed from the PCV valve. This coupler will accept the rubber hose to the catch can.
4. Reinstall the elbow fitting onto the PCV valve, pointing toward the front of the truck. This step helped me better determine how to route the rubber hose and where to cut it.
5. The rubber hose with the kit comes as one long piece, DO NOT cut it until the catch can location is determined.
6. Assemble the hose barbs to the catch can with thread tape and mount the bracket. Originally I used the brass hose barbs that were included with the kit, however I chose not to use the straight fitting in either location. It would cause the hose to kink over time. So I purchased black nylon, glass reinforced, elbow fittings (Eldon James L4-8GFBN) from Amazon that were actually a tighter fit with the rubber hose than the brass fittings. The catch can ports are ¼-18 NPT.
7. Install the catch can - I installed the bracket on the brake booster and sanded the corner down to fit in the recess on the brake master cylinder. I used an M8 flange nut and medium threadlocker to secure the bracket.
8. Install the rubber hose on the PCV fitting, route it to the catch can, trim to length and install it on the hose barb on top of the catch can. Before cutting the hose to length, I marked it with tape and then routed the other end from the exit port back to the PCV tube just to be sure - measure twice, cut once! A little WD-40 on the barbs and PCV tube makes it easier to install the rubber hose.
9. Install the 2nd hose from the exit side of the catch can back to the PCV tube that runs to the intake. I ran this hose behind the brake booster to keep it away from the exhaust header.
The catch can from Elite Engineering is a high quality, well designed and manufactured unit, so it wasn’t cheap. The kit I purchased was $160, but after seeing its construction and attention to detail, the cost fit with its workmanship. I try to purchase upgrades for my truck that support American jobs and in my opinion this kit is worth the cost. I know Billet Technology manufactures a high quality catch can that is very popular with 4th gen Hemi owners, but there are a few reasons why I chose the Elite Engineering kit. The “Z” bracket mount on the BT kit would be difficult to use on my truck, the EE bracket worked better. The kit from EE also came with a spare O-ring for the cup, which is nice to have. The EE inlet is on top while it’s on the side of the BT can - I needed the top inlet based on my mounting options. The base kit from BT is $135 but is $160 from EE which includes several color choices. If you chose a color from BT, each kit costs the same.
Not all 3rd gen Rams with the 4.7L have the same PCV hose routing, this install was on a 2006. You may want to update your truck by reviewing TSB 25-002-08 (found here). Some earlier models (02-05) have the PCV valve on the oil fill tube, this TSB details the parts and steps to convert it to the valve cover. The revised routing is much simpler and less likely for condensation to freeze during winter months.
I hope this information is helpful to someone who is considering an oil catch can on their 4.7 motor.
