What causes these faults -- following the manufacturer's break-in procedure? Again, where are the data?data is in the people’s hands that have tore apart motors and seen the leaking pistons, the oil consumption and the blow by everywhere.
What does a builder do? What builder has designed, manufactured, and supported more motors than Subaru? How valuable is less experience compared to more?its just common sense when you talk to builders about this stuff.
At best one can learn about that specific motor. To get a meaningful idea of what a process will do to a motor, isn't sample size important? Wouldn't having to design and test and support, say, 100.000 motors provide more insight than tearing down one, or ten, or 1.000? Who's built and supported 100.000 or more motors?... Subaru.when you tear down your own motor and see how your break in worked, you know.
I understand, I think, what point you are making -- and if I don't, I am in no way saying that's anyone's fault but my own. I just don't see a justification since everyone's collective experiences are still going to pale in comparison to those of the manufacturer.all i said was dont follow the manual, "the way people imply it."
No. I don't have to. They're working for the people most experienced with those motors. If I had one of those motors, I'd follow their directions instead. It is likely their directions will be similar to those given by Subaru, isn't it?The last part of the assembly line is your car on a dyno doing full redline runs, well above the 4000 rpm limit wonder why that is??
