Bypassing is often a smart thing to do. If you've got bypass tubes on your shocks, you've got more suspension control and adjustability than with smoothies. If you're on a trail and happen upon an obstacle that's likely to damage machine or wallet, it's good judgment to bypass said obstacle and keep your ride alive.
Bypassing also turns out to be a smart thing when it comes to filtering your oil.
The Filtration Challenge
Your engine oil needs to be filtered in order to keep large particles of whatnot from damaging your engine. At the same time, proper oil flow volume must be maintained for the same reason. Low oil flow also means engine damage. As such, your stock oil-filtration system is designed so that 100 percent of the oil passes through the filter. Not coincidentally, your stock filter is called a full-flow filter. In order to maintain full flow, the filter can't be too fine. Stock oil filters typically work on particles down to 20 microns in size. The problem is that particles two microns or larger will eventually damage your engine.
Bypass Filtration Explained
A bypass filtration system takes a portion of your engine oil and diverts (bypasses) it into a second filter. The second, or bypass, filter is capable of filtering particles as small as two microns. Since only a portion of the oil goes through the bypass filter, there's still sufficient oil flow in the rest of the system to prevent low flow engine damage. With a bypass filter, you effectively change your oil every time you get behind the wheel and drive more than a few blocks. This means your engine will last much, much longer and that you can go further between oil changes.
The Old Way
Bypass oil filtration systems are nothing new, but they're a relative newcomer to the light truck enthusiast world. In the past, bypass filtration was commonly found on commercial, heavy-duty trucks. Installing a traditional bypass filtration system means tapping a source of oil flow, running it through a bypass filter, and then returning that extra-clean oil to the rest of the oil. The tapped source is often found at the oil pressure sending unit, and the returned oil usually goes into the oil pan via special plumbing. Tapping the oil source can be time-consuming, and running a return line into the oil pan usually involves cutting and welding. Installing a traditional bypass filtration system can be a daunting task. A disadvantage to traditional bypass oil filtration systems is that the oil flowing through the bypass filtration system is "sidestreamed," which reduces the oil volume that reaches the engine's main bearings, camshafts, and other vital engine parts.
The Topdog V Difference
The Topdog V bypass filtration system from Pareto Point Industries makes it easy to install a bypass filtration system on your truck. Instead of tapping into an oil source and plumbing a return line into your oil pan, the Topdog V makes all of its connections to your stock oiling system at a sandwich adapter that goes between your engine and your OEM full-flow oil filter. What used to take several hours now only takes a few minutes. Besides the easy connection to your engine via the sandwich adapter, the Topdog V system does not "sidestream" any oil. Instead, the oil from the bypass filter joins in with the oil from your full-flow filter. This means 100 percent of your oil is available to protect your engine. This is critical in hot weather and under heavy loads.
The Topdog V comes with a sandwich adapter, a hex-shaped adapter installation tool, a bypass filter, a bypass filter mounting bracket, four push-on hose fittings, and high-grade, abrasion-resistant hose. The trickiest part of the installation is finding a suitable location to mount the bypass filter and adapter, but there's enough hose included with the kit to allow you to remotely mount the bypass filter virtually anywhere in the engine bay. We used basic fabrication tools to custom build a mounting bracket for the bypass filter and guide brackets for the oil lines.
