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?

I think this is the intermediate shaft. This is the same issue my neighbor had.

Not uncommon I hear.
