Single row or double row?
The other day, curiosity got the best of me and I crawled under my 2001 BoxsterS and wrote down the engine serial number. My engine number is M96.2167103372. According to the lists of engine numbers I have seen published in the Pelican book and elsewhere which show the change points for double to single row, my engine should have a double row IMSB. My question is whether anyone has kept track of engine numbers of cars with the single row bearing to see what the earliest serial number for the single row bearing would be? I know the only way to be certain is to pull the transmission and have a look, but I wondered if anyone has seen a single row bearing in an engine with a serial number as low as mine? Is roughly 8,000 engines away from the published change point enough to be sure I have the double row? John
