Installing ByPass Oil Filter Components on the 5.0 Cummins

• Now that we have seen what the systems looks like with everything installed, let's take a look at installing the individual components
• NOTE: Since we are merely showing the system and component installation to give you an idea of the installation process, general shop practices such as "set the parking brake...:", disconnect the negative battery cables" or "wear appropriate personal protective equipment (PPE)" will not be discussed below.
• Below we will look at locating and drilling holes to mount the bypass oil filter mount
• Replacing the OEM full-flow oil filter with the engine filter adapter
• The illustrated Installation Instructions (pdf) are quite detailed if, at this time, you want to see the details.

Where to Locate the Filter Mount

• I elected to go with the right side of the engine bay to mount the filter mount
• Remove the right battery
• Attach the bypass oil filter to the filter mount (not shown) and determine which position will allow you to remove the oil filter for filter changes
• Position the drill template (post card looking paper on the body)
• Center punch the hole locations using the template
• Drill the holes (below)

Install the ByPass Oil Filter Mount

• Install the filter mount with the hardware provided in the kit
• In the top photo the two street-elbows are not installed in the top of the mount
• In the photo below the two street elbows and fittings have been installed
• The battery is back in place
• Almost ready to start routing and connecting hoses.

Install the BK1104 Engine Adapter

• View looking up and aft from the left front of the engine
• The OEM engine oil filter is removed
• BK1104 engine adapter (blue ring) is installed on the OEM filter boss
• Notice that there is a 90-degree fitting inserted into the side of the adapter; pressure oil is ported from the engine to the bypass filter via this fitting
• Make up your hoses/fittings and route the hoses.
• The next photo (below) shows an AMSOIL EaO80 full-flow oil filter mounted on the adapter.

Filter Adapter with Full-Flow Oil Filter Installed

• View looking up and aft from the left front of the engine
• AMSOIL EaO80 full-flow oil filter installed on the BK1104 adapter
• Oil pressure line that feeds the bypass oil filter is connected to the 90-degree fitting

5.0 Cummins Return Oil Through Oil Fill Cap

• View looking from left to right side under-hood
• After the engine oil passes through the 2-micron bypass oil filter, the clean oil is returned to the engine here
• The blue machined billet oil fill cap is tapped for the elbow shown installed
• The billet cap has a swivel in the center to allow the cap to be removed without disturbing the oil return line.

Nissan Titan XD 5.0 Cummins By-Pass Filter Kit

• View looking from right side over to the left side
• Engine is filled with ~11 quarts of AMSOIL 5W-40 (DEO) synthetic diesel oil
• All bypass components are connected and no leaks

• A percentage of the engine oil is continuously flowing through the 2-micron by-pass oil filter.
