Those damn rods! but wait what about the crank?
With all the discusion about the engines being blown lately, did anybody consider the crank as the culprit? We all know the rods are a weak link, but the crank may be at fault! NO? I mean if the crank fails to flow the right amount of oil for cooling & lubrication, then there go's the bearing, then the rods. The damage could be mounting & mounting, you wont know until boom!

...tomThe crank would set me back another $3 to 4 K... and I rather put that money onto the head with cams...
I should be good for a while... my weak link is the crank if any. But how often do we really stay in it for 15 minutes nonstop at 8K rpms...

I understand,but you could of done work to the stock crank for pennies once the engine was apart! Epecially for those RPM peaks! It's just an added security measure. IMHO....tom

Just to put in perspective the detail work going in to our setup, we are having Porsche Motorsport rod bearings custom clearanced to each specific rod journal. Each individual bearing will be set to its own journal. Rod bolts will be prestressed as well. The crank bearings will have machined grooves in them to increase oil flow as well... The case will have oil gallery work to increase the oil flow to the crank bearings....If I have learned only one thing from Kevin, it is that the details are what separates the good from the great....kevin
