Rod Bearings

Is it me or are the price quotes to fix the N55s are higher than S65s for rod bearing issues?

From what I have seen and heard, the N55 is far riskier to replace the bearings in as the camshaft journal is much more sensitive to being warped.

As far as price, im sure it comes down to design and the S65 allowing to to reach the bearings easier.

Yes, my mistake. The crankshaft journals are what can end up being warped.
