Quick RMS seal question.
 
I was told the RMS issue is not due to an out-of-round Crank but is due to a defect in center-line boring the block.

And that it affects all Boxster years untill present.

Does anyone have insight to this?

Thanks.

On some engines the crankshaft is not concentric within specs to the bore for the seal.

There are several theories (as you have indicated) as to why our cars are prone to RMS issues (as are the 911s). Of course Porsche denies they have a RMS problem but we all know that they do.

However, I would assert that the most important issue here is that the company that has engineered our masterful cars cannot or will not get the issue resolved, irrespective of WHY it happens.

In my experience, a RMS can strike on any year Box or 911 and I have not found any particular year to be suspect. They all seem to be.

I do know that I have had several 911s that have had multiple RMS repairs and some that have had none. To me, that seems to indicate a build issue rather than design.

Alas, that is just my opinion and the issue goes on.

I can only imagine how many thousands of hours they have spent looking into
this problem.
Porsche hasn't fixed the problem because they have no idea how to fix it.
The fact that the new 987 was reported to have had an RMS failure already tells
me they are still scratching their heads.

Geesh! That's not good.
