After spending a couple of days thinking about it, I have decided to clean out the tube as best I can, install the new bearing and DOF, and reassemble. I spent about 8 hours this weekend doing just that and am waiting for the sealant and new oil plug to arrive this week. I ordered Loctite 5900, but have since read that Drei Bond is a better way to go. I am going to call the local VW dealer and see if they have it or can get it fairly quickly, otherwise I will place another online order.
In the end it turned into an economic decision. I do all of my own wrenching, short of internal engine stuff. I have done that type of work before, but never on a Porsche and I don't have the specific tools or knowledge for an engine tear down and rebuild. I could acquire the tools and knowledge, however, when rebuilding an engine there is no sense in doing just the part you think needs to be replaced, you should check and replace everything necessary from pulley end to flywheel end if you're already there. Since I would be having a shop do the work, the bill would be in the $12k range, give or take. A used 3.2 is around the $5k mark and a used 3.4 is not much more than that (what not upgrade if you can?). There is an X% chance that the metal specks were from the original IMSB and a Y% chance they were from the replacement IMSB, and a Z% chance they are from some other undiscovered source. (You can decide what values you place on X, Y, and Z, but I place a high number on X because of the location of the debris). The car was running just fine when this project began and
may continue to run just fine from here on out, thus costing me $0 of engine parts/work. If it does give up the ghost, I will swap it myself and be out about $5k. I know what a lot of people will be thinking, "you have no idea what the condition of the donor engine will be and could be inviting more problems". True, but most used engines come with at least a 6 month warranty and even if the 2nd motor goes poof, I will do the same and replace it, being out another $5k ($10k total + fluids and other misc expenses). I would still be ahead of the price of a rebuild of the existing engine. That's why I chose what I did.
So, I'll install a magnetic drain plug to catch any further ferrous particles hiding on the inside, change the oil every 1000 miles, and see what happens.
