Warmly recommended: clean the existing PCV valve in thinner, or replace it with a new one.
Locate the PCV Valve if you haven't done it so far. Wikipedia says regarding possible locations: “The PCV valve connects the crankcase to the intake manifold from a location more-or-less opposite the breather connection. Typical locations include the opposite valve cover that the breather tube connects to on a V-engine. A typical location is the valve cover(s), although some engines place the valve in locations far from the valve cover.”
Your car's maintenance manual (find it at your the auto parts store) tells you right away where each major part is located. Usually be the first couple pages in the engine-related book. Another source is www.AutoZone.com – click “Repair Info” and then select “Components Location”.
Under the hood, choose an easy to reach space for the PCV Enhancer. The device itself needs only a small space - but remember that you'll need access to check the contamination level and also be able to reach it with your hand for cleaning.
The best position would be below the level of the intake manifold (to enable water to sink into the device after the engine has stopped, rather than dripping back into the engine). Due to its plastic parts it is also recommended to keep the PCV Enhancer away from engine heat as much as possible, but no more than 2 feet away.
I chose a location at the of level of the PCV and easily accessible from the side of the car, near the brake drum.
If you want to, and if there is something in the vicinity to hang on to, you can add brackets to the PCV Enhancer (use the 4 threads at the upper body of the PCV Enhancer, they look like they'll take standard 1/8” screws). Then install those brackets to the car. If not, attach the device using bungee cords. To protect the device it can be positioned into a plastic can and/or padded with durable foam.
Disconnect the hose attached to the PCV Valve. Make sure you understand where the air flow is going in the system (start the engine for a second and see for yourself if you're not sure). This is important because the PCV Enhancer has a certain AIRFLOW DIRECTION even though it may seem symmetrical at first look.
Connect the OUTPUT of the PCV Enhancer [the black filter housing is embossed with clear IN and OUT markings] to the intake manifold port for the PCV Valve, as shown in the picture below. Use 3/8” hose. You can use the original hose if it can reach the location of the enhancer.
IMPORTANT: The hoses should not have any low spots that might collect water (since this water will freeze in cold weather and block the PCV system). Any liquid that may accumulate in the in or out hoses should be free to run into the enhancer when the engine is shut off.
Inspect the installation visually. Make sure all hoses are secured with clamps. Make sure the filter bowl (the transparent part) is tight – hand tight only!
Add a cap at the bottom opening on the PCV Enhancer. Closing the valve will not actually close it because the Husky filter was designed for POSITIVE pressure and will stay open under vacuum. The cap can be any ¼ cap, even as simple as a piece of hose with a bolt tightly screwed into it.
Start the engine and check the system by observing the transparent filter bowl. You should be able to see condensation – this is an indication that the system is working.
It is advisable to protect this device by placing it into a plastic bowl or bottle.
