As well are the aftermarket fixes really a fix? Or has it ever happened aft the fix?
So i should take a dip into the water cooled pool eh?  |
The cause of the problem has been researched by experts in the Porsche business and has been found to be loss of lubrication to the bearing, The reason for this is that the original bearing is a sealed unit, with grease packed inside - similar to a rollerblade wheel bearing. However, over time, the seal wears just enough to allow the grease to escape, yet not enough to allow engine oil in the area to seep in sufficiently enough to lubricate the bearing. It scores eventually, and can eventually just fail. The newly designed bearing by LN Engineering redesigns the bearing to eliminate the seal and allow engine oil to freely lubricate the bearing. Additionally, the bearing is made of a much more robust material that resists scoring, even when dry.
It's something Porsche should have come up with originally.
