In the manifold there is a set of buterflt valves .
the shaft has worn out and 1 of the plates fell off .
I cannot find a used one, can i remove the shaft alltogether and plug the shaft hole? what is the purpose of this shaft anyway ?
it is the intake as the plate that fell off was found next to the intake valves ,and the shaft being loose is causing a bad vacume leak..
yes its the middle part of the manifold
the dealer sells it for 400 and change you can try what your doing if it doesn't work buy a new one i don't see why it wont work those things rattle like crazy when the car gets a lot of miles on them for me i get paid to replace them so i do if it were my car i would take them off
Engine Intake What is the plenum area of an engine's intake manifold? Is it just a void after the throttle body?
To add nitrous oxide injection to an engin, the fuel/gas mixture:
....."preferably wants to be injected right under the carb in the Plenum area, or for fuel injection, right after the throttle body PROVIDED that this is close to the engine! If its not, then inject at the last part of the tube before it enters the plenum area, so that all cylinders get the same amount of additional fuel/gas mixture"
.....but i can not find any info on exactly where the "plenum" or "tube" is located ! Thanks for anyone who can explain this detail clearly
The plenum chamber is the part located between the throttle body and the part of an intake manifold where it splits to go to individual cylinders, used to distribute the intake charge evenly and to enhance engine breathing. It is, indeed, a box-like void. They're saying that if you can't get at it you should use the tube leading into it from the throttle side instead.
When VW was being conceptualized, their primary goal was to build a people's car. Something that ordinary people can afford and yet be functional enough for their lifestyle. Hence the VW beetle was produced. Adolf Hitler one of the people who supported the concept of the beetle. VW has been making quality cars since then. As the vehicles were continuously upgraded to suit the people's needs, various car parts were also enhanced to fit the vehicles design. One innovation that have helped the engine is the VW cold air intake.
A VW cold air intake is a system used to bring down the temperature of the air going into a car. Its primary purpose is to increase the power of the internal-combustion engine. A secondary goal is to increase the appeal of a car by changing the appearance of a car's engine bay and creating an attractive intake noise. All VW cold air intakes operate on the principle of increasing the amount of oxygen available for combustion with fuel. Because cooler air has more density for a given volume, cold air intakes generally work by introducing cooler air from outside the hot engine bay. However, the term cold air intake is often used to describe other methods of increasing oxygen to an engine, which may even increase the temperature of the air coming into an engine. The make of cold air intakes has a direct effect on the type of performance one wants or needs. One strategy used in designing cold air intakes is increasing the diameter of the air intake, that allows increased airflow. Another way is smoothing the interior of the intake to reduce air resistance. Providing a more direct route to the air intake, can also result to a better VW cold air intake.
Intake systems come in many different styles and can be constructed from plastic, metal, rubber or composite materials like fiberglass, carbon fiber or kevlar. Due to the limited time, air actually remains inside the intake tubing. The materials often do not impact a kit's ability to deliver cool air. The most basic cold air intake replaces the stock airbox with a short metal or plastic tube leading to a conical air filter, called a Short ram air intake. The power gained by this method can vary depending on how restrictive the factory airbox is. The placement of the filter is usually directly in the engine compartment. The overall benefits depend on the specific application. Power may be lost at certain engine speeds and gained at others. Because of the increased airflow and reduced covering, intake noise is usually increased. This effect is usually amplified on applications where a resonator, a part intended to reduce intake noise on some vehicles, is replaced by the intake.
Though the VW cold air intake can really help the engine, there is still some potential risk when using it. One thing is to avoid getting water in the engine by installing a water shield in the intake or not driving in the rain at all.
VW cold air intakes can really have a powerful effect on the car. But considering the possible risk, it should also be properly maintained just like any regular car part.
