New Engine Pre Run In--- How is this so??

[insatiable]

Thanks Guys for these comments.
I had assumed the engine was new and not a rebuild or thereabouts. I did note that the new engine No. is some 160,000 newer than the original which would have been built about Dec 02 .
Guess I will er on the side of caution and keep the lead out of the right foot for a while.
As to the reson for the failure at 27000kms. I was told the "jack shaft " bearing failed and cracked the housing which is why I dumped about 8l. of oil onto the road! Which begs the question what is the jack shaft?
Cheers,
Glenn
