e s catch, can you tell me exactly where it is and what it looks like. i have looked all over this thing. thanks randy the model # is 8905

How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
The PCV valve allows air to be drawn through the engine`s crankcase, using the vacuum of the intake manifold to do so. The air enters through the crankcase vent side and then is sucked into the intake manifold. This helps draw out moisture from the crankcase.
A typical catch can plugs into a hose running from the top of your engine`s crankcase to the intake manifold.
The oil catch can is necessary for direct injection engines. In port-injected engines, the fuel is sprayed into the intake manifold, and it works as a cleanser. It washes off the oil and reduces debris build-up.
An oil catch can is a canister that is installed, or spliced into the intake system between the positive crankcase ventilation valve and the intake manifold, and its function is to “catch” excessive amounts of oil that might be present in the intake system before it can enter the cylinders.
A clogged hose or PCV system or inoperative valve can increase oil consumption because pressure builds when the vapors in the crankcase aren`t allowed to flow into the combustion chambers. That additional pressure can force oil past seals and gaskets.
A catch can is an addition to the breather hose between the PCV & the intake system. This breather hose from the PCV is disconnected from the air intake and either replaced or connected directly to the input of the catch can.
The oil catch can is placed between the pcv valve and the crankcaseOpens a new window. The excess oil collects in the catch can, which must be periodically emptied and rinsed. Although there are some commercial oil catch cans available, some people create homemade models from old food jars or steel wool.
Catch can legalities
Catch can`s are 100% legal, and on some well designed diesels they actually come as standard.
Your car`s engine has a very intricate way of taking care of itself. For example, when oil blowby occurs, the engine is set up to recirculate the oil through the engine again, however, that can lead to power loss over time unless you install an oil catch can.
Curing the nonexistent problem of oil blow-by with a catch can, which pressures up the system and blows a seal, allowing sump oil to escape could have the nasty feedback effect of catastrophic engine failure, and you will not be covered by warranty.
Even with meticulous maintenance, sludge build-up is inevitable. Therefore, the best way to keep a CRD diesel engine running at its peak performance always is by using a Ryco catch can. A catch can separate oil, hydrocarbons, soot, and condensation from the crankcase gasses, making the recirculated air cleaner.
“Yes, I would definitely recommend a catch can. Now, the main issue is when the oil and the EGR gasses mix and it turns into this crusty looking stuff. The next problem you have is that the oil vapour goes through the whole system. You can actually get a build up of it, particularly in your intercooler.
Although its never recommended to drive any longer than you should with a damaged component, driving 12 hours with a damaged PCV valve could be very risky.
A stuck closed PCV valve results in excessive crankcase pressure. It forces oil past the engine`s seals and gaskets. A stuck open PCV valve or leaking hose results in a large vacuum leak, a rough idle, and drivability issues like surging.
An oil catch can will not add any power to your vehicle, which is why it`s so often overlooked. However, an oil can will ensure you always have a clean intake, keeping your engine running better for longer and ensuring you don`t lose horsepower over time.
It leaves an oily residue throughout your vacuum and intake system which can over time clog valves, sensors, etc. This is particularly dangerous for boosted cars, as it can cause your blow-off/bypass valve or wastegate to stop functioning properly, or in some cases at all.
They can significantly improve performance by catching residual oil and preserving the valve and intake manifold from contaminants. They can also improve fuel economy by capturing oil that would otherwise be burned in the engine and recirculated back to the crankcase.
Yet if modified, the addition of a catch can is almost mandatory to ensure a healthy, equalized crankcase atmospheric pressure as well as a clean, uncontaminated intake charge – which will result in greater engine efficiency and thereby, increased acceleration and horsepower.

When your PCV valve is malfunctioning, it throws the air to fuel mixture out of balance and can lead to poor performance and rough idle, as well as misfires. In the very short term, these issues should not damage your car, but if you don`t fix the issue, you can do lasting damage, so it`s best to get it fixed promptly.
