Following last month's CFM Plus intake manifold install on the 7.3L Power Stroke, we decided to bring you another easy bolt-on option for your '991/2 to '03 Super Duty-BD Diesel's crank case vent filter kit for the 7.3L Power Stroke. This is an aftermarket product that prevents the factory crank case breather system from introducing oil into the air intake. By adding a filter and oil catch can system to the factory closed crank case vent system, its kit also prevents crank case oil vapor from contaminating the intake tract, which keeps intake boots from blowing off and increases boot life. The system also reduces the amount of oil found in the intercooler. Since it's a breeze to put on, the guys at Diesel Tech in San Jacinto, California, had our system installed in about an hour. Here's how it went. BD Diesel's kit required just a few wrenches to get the job done: 1/4-inch, 7⁄16-inch, 1/2-inch, 9⁄16-inch, and a Phillips screwdriver. First to come off our '02 Power Stroke was the air filter and intake tube.BD Diesel's kit required just a few wrenches to get the job done: 1/4-inch, 7⁄16-inch, 1/2 Next, the guys at Diesel Tech removed the turbo inlet tube and pulled the hose off the factory breather box at the rear of the driver-side valve cover.Next, the guys at Diesel Tech removed the turbo inlet tube and pulled the hose off the fac Then the two Phillips head screws that hold the breather vent box on were loosened and it was removed. After that, the large O-rings on the valve cover were replaced with the supplied ones (PN 1302187), the breather vent box was rotated 180 degrees, and it was reinstalled using the new hex studs and O-rings (shown).Then the two Phillips head screws that hold the breather vent box on were loosened and it With the breather vent box snug (be careful not to overtighten or it will crack), the inlet hose (PN 1302178) was installed onto the breather vent using one of the supplied spring clamps.With the breather vent box snug (be careful not to overtighten or it will crack), the inle Next, the CCV canister was mounted to the supplied stainless steel bracket via two 5⁄16-inch bolts, washers, lock washers, nuts, and then the supplied drain hose was connected to the CCV canister with an included spring clamp.Next, the CCV canister was mounted to the supplied stainless steel bracket via two 5⁄16-in With the CCV canister secured to the mounting bracket, it was placed over the hex studs in the breather vent box and tightened using the supplied Nyloc nuts and washers. After that, the rubber breather hose was connected to the upper port on the CCV canister via a spring clamp.With the CCV canister secured to the mounting bracket, it was placed over the hex studs in The second hose was then connected to the turbo inlet tube with another supplied spring clamp, and then reinstalled on the engine.The second hose was then connected to the turbo inlet tube with another supplied spring cl Then the new hose was connected to the lower port on the CCV canister. The idea behind this design is that air will exit the valve cover, travel into the top port of the CCV canister, and allow clean air to leave through the lower port, which flows back into the intake system. BD Diesel recommends the filter in the canister (PN 1302171) be changed every 30,000 miles, or once a year.Then the new hose was connected to the lower port on the CCV canister. The idea behind thi After that, the air intake was reinstalled and the fasteners were double-checked for tightness. The Diesel Tech guys also made sure no hoses were kinked or pinched off. Then they lifted the truck up in order to install the catch can underneath the CCV canister.After that, the air intake was reinstalled and the fasteners were double-checked for tight Before the catch can could be installed, the supplied barbed fitting was threaded into the top of the catch can using a 9⁄16-inch wrench and tightened until it bottomed out. Then the supplied 1/4-inch bolts, washers, and lock washers were used to mount the catch can to the provided bracket.Before the catch can could be installed, the supplied barbed fitting was threaded into the Once under the truck, the CCV canister's 1/2-inch drain hose was located (arrow). BD Diesel recommends you utilize an existing hole in the bottom of the framerail (on the driver side, just behind the crossmember) when mounting the catch can bracket.Once under the truck, the CCV canister's 1/2-inch drain hose was located (arrow). BD Diese The guys at Diesel Tech used the supplied hardware and mounted the catch can to the framerail, then connected the 1/2-inch drain hose with the last spring clamp. Notice the red lever at the bottom, which is shown in the closed-valve position. To open the valve and drain the catch can it simply turns downward 90 degrees. BD Diesel recommends the catch can be drained every oil change.The guys at Diesel Tech used the supplied hardware and mounted the catch can to the framer SOURCES Diesel Tech 1685 S State St. San Jacinto CA 92583 951-766-5777 http://www.dieseltech1.com/ BD Diesel Performance PO Box 231 Sumas WA 98295 800-887-5030 www.dieselperformance.com By Mike McGlothlin Enjoyed this Post?
