Getting closer every day to finally pulling the trigger on a Boxter purchase. Cannot say how pleased I am about the topics / readings on this blog; the education is priceless. I think Jack Raby and Pedro have done an enormous service for us all; I for one would like to thank them both.
Please understand I am not a technical type – I am only pondering the IMSB situation and fixes, and asking questions. I hope someone with a much better technical grasp of the situation can explain some things.
If Pedro (Pedrosgarage) is correct and a small amount of oil weeps (seeps?) through the original sealed bearing into the shaft, (which in turn turns acid), why can’t drain holes be drilled into the shaft? Would it weaken the structure? Would oil, which might be slung outwards from inside the shaft, cause havoc somewhere else in the engine?
Utilizing the DOF fix, the bearing has one end “uncovered” (for lack of a more technical term) in order to have pressurized oil from the engine. If the other side of this bearing stays sealed (is it?), wouldn’t the pressure from the oil system eventually force even more oil past the sealed end of the bearing and into the tube? Why is this a good thing?
Another question I am wondering about – perhaps someone who has experienced the process can supply an answer. Regarding the Flat Six Innovation / LN Engineering fix: when suspect bearings are removed from the shaft, does oil in fact come out? How does car mileage affect the quantity of oil in the shaft?
Please excuse my lack of knowledge here. As stated, I have just been pondering and how I will handle it all when I do finally buy a Box. Thanks in advance.
