Vented sounds interesting.
If you consider that the IMS is a sealed tube, and that the air gas volume inside is constant, you'll have a very different air overpressure at let's say 10 degrees celsius and 110 degrees celsius. At the same time you'll have a constant underpressure of around −2 mbar in the engine. Does anybody know the inner volume of the IMS tube, so we can calculate the air overpressure at different engine temeratures?
This might also be a cause why the OEM IMS sealing is stressed by temperature change.
The term vented is used as ventilation i think. How does that work? Because if you do not use a sealed bearing the pressure in the engine should be the same as in the complete engine. Or am i wrong?
PS: sorry that i use the metric system.
