I have a rudimentary knowledge of how an engine works, and if you have seen my other post I have been plagued by IMS demons. Now I have a question, and let me know if my thought process is wrong. It has to do with the tube the IMS sits in. Where in the oil cycle is it located? If I understand engines right it goes like this (I wish I was better at pictures, but I will try to describe it. Oil flows in one direction. Oil from engine goes to oil pan, oil from oil pan goes through filter, oil goes through pump to engine. From engine back to pan. It's closed circuit type thing. So where is this tube in the circuit? Before or after the engine? If its after the engine then all the debris goes through the filter first and gets trapped. If its before the engine then all the debris circulates though the engine before going to the pan. Does this question make sense?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The intermediate shaft tube was never supposed to get oil inside it. That is why Porsche used sealed bearings in the shaft (after the bearings were packed with grease). The fact that the seals on the end of the tube fail, allowing hot oil into the shaft, eventually making the bearing seals fail, washing out the permanent grease with said hot oil, and then keeping the oil trapped in the tube/bearing allowing it to accumulate moisture and other contaminants to really do a numer on the bearing. The shaft "sits" towards the bottom of the motor but is not a part of the "oil circuit" as you describe it.
