A combination of imitation and competition between auto manufacturers has bred some of the best cars of all time. As certain cars become benchmarks, auto manufacturers and marketers take aim at their. What defines success when it comes to a car? There are plenty of ways you can quantify and qualify the merits of a specific make or model. There is price, performance, sales success, and those. That last 1 percent was when the engine was operating at wide-open throttle WOT where engine vacuum drops to nearly zero in the intake manifold, which disables the PCV system.
This test revealed there was a clear need for an adjustable PCV valve that would establish a sufficient flow that would create a vacuum in the crankcase. The Wagner valve is beneficial because the optimal transition point between these flow modes can be tuned to each specific engine using a vacuum gauge. Stock PCV valves only offer one airflow path that is not adjustable in any way. This lack of sufficient vacuum in the crankcase is important because gasket leaks are amplified when pressure in the crankcase is sufficient to push the oil past the seals.
This occurred even after trying two different PCV valves. Surprisingly, in addition to these improvements, our minor but annoying off-idle stumble when the clutch is engaged has all but disappeared. All of these improvements were the result of a change to a simple adjustable PCV valve that took less than 10 minutes to tune and install.
As mentioned earlier, early LS engines tend to fall into this excessive oil consumption trap and the more-efficient Wagner PCV valve may actually aggravate those issues. This is because along with the additional flow through the crankcase is the inevitable oil that is pulled along with the vapor. Wagner suggests combining a vapor separator tank along with the dual-flow PCV valve. The separator is really nothing more than a small reservoir with inlet and outlet fittings and a small drain petcock on the bottom.
This also allows you to adjust the idle circuit on the Wagner valve to be slightly more aggressive, using the reservoir to separate the oil from the vapor. We substituted better, heavier wall vacuum hose to replace the cheesy stuff the reservoir was shipped with. We plumbed a filtered air inlet line from the throttle body that sources upstream of the throttle blade and ran a Dorman PCV valve hose with molded bends to prevent kinking into the passenger side front LS valve cover inlet.
If after a few hundred miles of use with the billet PCV valve you find the system is still pulling quite a bit of oil through the separator, one improvement for Gen III LS engines might be to use a larger vapor separator. The external nipple would then be attached to the inlet of an inline PCV valve that would connect the vapor separator canister. The PCV is mounted on an body which looks like a breather but it is not. The body is just there to twist the PCV valve in the valve cover.
I am going through this same process on my 68 with similar MP valve covers. Thanks for the pics. Last edited: Jun 14, SPF Required said:. I am tracking you now.

A PCV valve hose failure can cause poor fuel economy, a Check Engine Light to come on, and can cause the engine to run rough. Step 1: Locate the PCV valve.
The PCV valve is located on a valve cover, which is in various locations on the valve cover depending on the make. Step 2: Remove the engine covers. If there is a engine cover in the way of the PCV valve hose, you will need to remove it. Step 3: Locate and remove the PCV hose. Spring hose clamps are removed by using a pair of pliers to collapse and slide the clamp away from the hose end. Quick disconnectors are removed by releasing and slightly pulling to remove.
This requires first examining how the quick disconnect works. Once you have identified and removed the connector, remove the PCV valve hose by gently twisting and pulling the hose away from the fitting. Step 4: Install the new PCV valve hose. Position the clamp on the PCV valve hose. The hose will typically slip right over the fitting when installing. If needed, you can apply a very thin layer of grease to help slip it over the PCV valve or the intake fitting. Step 5: Clamp the PCV valve hose.
Clamp the hose by using either the clamps provided or the old clamps. Step 6: Secure the clamps. Make sure to secure the hose ends with the type of clamps it is designed to use. Step 7: Replace any removed covers. Reinstall any engine covers or plastic covers that were removed.
