This view is becoming too common:

I neglected to post this picture during the build - it shows how the restrictive collector was removed and re-jiggered for a flanged 2.5" Y-pipe outlet:

After your blower has eaten a roller bearing cage and roller, here's why you don't just change the oil and filter and hope for the best:

Not only do those pieces of steel and aluminum go into the cylinders and get smashed into the valve seats, some make their way past the ring end gaps and find their way into the sump:


from where they can migrate into undesirable areas - like between this rod bearing and journal:

The main bearings and journals look ok:


Since I had the piston pins pressed instead of installed as floating, I'm hoping I can clean up the pistons without worrying about contamination between the wrist pins and bushings.... since the mains are ok, I'm assuming the oil filter worked and kept stuff out of the oil gallery. The rod journal contamination probably was from sump splash which shouldn't have gotten on the wrist pins.

Anyway, it looks like a cylinder rehone, crankshaft polish, new bearings, rings, a valve and seat dressing, new valve seals, gaskets and oil seals..... and a very thorough block, piston, rod, oil pickup and oil cooler/lines cleaning is in order.

The Magnacharger rep called to say they've inspected the blower and found that I experienced a rear bearing failure..... really? <img src="/forums/images/graemlins/lol.gif" alt="" /> They're now rebuilding it.
