Yeah, I realize that. But, to the extent overall the 911s are worse than others, perhaps that's a contributing reason. Since no one described it, I thought I'd throw it out there.

When I recently had my 911 rebuilt, I received quite a bit of information, some of it contradictory about all this. First thing is that when my engine was back together, it was puffing oil smoke on start up and not stopping all that quickly. It ended up being most likely the Deves oil rings, rather than the OEM ones. Once we pulled it apart and put in the new OEM rings, it was much better.

Also, there were some engine rebuilders out there that absolutely insisted that the right way to rebuild a 911 engine was to put it together with the rings/cylinders mostly dry for immediate scoring and seating. They insisted that lube would delay seating, if not prevent it from happening ever. These were some pretty well known, publicly praised rebuilders (not MM!). One is even known for racing engines. Others absolutely insisted it was folly.

So, depending on which of these procedures are followed, the outcome can be largely different. The big question is, who is right?
