Is it easier to rethink the entire design that has been used since like 1988 on ALL turbo cars? Or is it easier to make it better? Your current idea provides no vacuum to the crankcase. I'm saying it's a bad idea so that others don't think it's going to work.cause it won't.Īsk yourself this. So the crankcase pressure will be vent to atmosphere freely (no PCV valve). I think I will connect the PCV valve opening and valve cover opening to a oil catch can with a breather.
I saw many professional race car/drift car also use this setup. If excessive oil is present in the PCV hose, replace the PCV valve (Type 948C) (2) with a new-style fixed orifice PCV valve, GM P/N 12572717(1). Venting PCV and valve cover breather to atmosphere is not the best way, but it works fine for many people. Remove the PCV valve and inspect the hose going to the intake manifold for signs of excessive oil being present.

I ended up tossing them and went with Motorcraft and oil use stopped. Here to fine tune my original DIY post on fixing the P2076 intake manifold tuning valve issues It's all here Send us a pic of your part if you don't see it here First, make sure your new PCV valve resembles the one in Figure 2 We stock a huge range of spa plumbing parts for your DIY spa repairs Reduction of power at higher RPMs Reduction of power at higher RPMs. Both started using oil soon after replacing the PCV valves with aftermarket parts.
Next post shows how a proper single catch can system needs to be configured.After reading ton of PCV system threads from Nissan, Honda, etc., the only ways to create vacuum are to connect PCV valve to exhaust or install electric pumps.Ĭonnect the PCV valve to intake is not a good idea, because having unmetered air entering intake will create idle/tuning issue, and the PCV valve will shut under WOT/boost. demarpaint said: I had problems with aftermarket PCV valves on two different Ford E-150 vans with the 4.9L I6.
In a naturally asperated carborated car of the past this check valve prevented any fuel/air mix from entering the crank case, in a modern car it prevents exhaust gases from the EGR system from entering the crank case, and in turbo applications like ours prevents the crank case from being pressurized due to the positive pressure in our intake manifold. The PCV valve itself is a check valve (one way valve) to prevent back flow from the intake manifold into the crank case. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV check valve closes and, thus, this hose experiences no flow. This maintains a negative pressure in the crank case and carrys out moisture and any blowby gases thus preventing corrosion and sludge buildup in the crank case. STM -10AN Aluminum Valve Cover Fitting - Front 2008-2015 Mitsubishi Evo X. In the stock configuration fresh filtered air enters the crank case through the vent connection and exits through the PCV valve into the intake manifold. This kit maintains the OEM closed system operation of the PCV valve while keeping oil and other contaminants from entering the intake manifold. Please Note: Removes the PCV Valve and re-us.
Here is a simple diagram of the stock configuration. In case people did not know, both the connections that are on the head (PCV and vent) are actally connected too the crank case, not to the air volume in the head itself. These Billet Specialties PCV valves are designed to fit into a standard 1.22 in. In addition, they recover quicker than the OEM valves which allows for better spool after shifts. Grommet Included Yes PCV Material Billet aluminum PCV Finish Polished Quantity Sold individually. I did some research so I could answer this question better since it has always bothered me seeing jacked up oil catch can setups.
