Question.Isn't there a lot more stress and and wear on a 6 cylinder motor putting out the same power as an 8 cylinder motor?I know my 6 cylinder cummins were a lot beefier then the 8 cylinder diesels but that was years ago.

A very long answer short; yes.

When you put a big 8 cylinders worth of air through a 6 cylinder engine the rings are going to load harder against the cylinders and the cylinder pressures are going to go sky high. (comparative speaking)

The reason the Cummins parts were bigger is because they had to be. They are putting the same amount of power through 6 pistons as other manufactures are putting through 8. So things like rods and wrist pins and things like that have to be built bigger and stronger to hold the power put through them. Think how big and strong the rod would have to be if you put 350 HP and 800 ft/lbs through a 1 cylinder Cummins!! :E

Ford performed a tear down from a abused engine in front of a live audience and actually measured some of the parts that illustrated that were still in factory specifications. Again I would have no concern of the engines internals holding up to boosted cylinder pressures.

You may think a 13% leak down is acceptable; I don't and don't know of any engine builder alive that thinks that's Ok.

LOL at Fords "factory specifications."

I still remember GM's "factory specifications" for BBC oil use. 1 qt for 600 miles was ok with them! :E

13% cylinder leak down must be just like the GM oil use deal and be within "factory specifications"! LOL :R

I don't know about the leak down test but the bottom line is it still made the same HP and Torque as it did brand new. :W

Perhaps GM should grow some ballz and perform a identical test with their V8 engine and dissect it for the world to see. :B
