Is the rear main seal problem...
 

engine specific? Meaning: more common in 2.5, 2.7 or 3.2.. or production years..

I read one statement where a tech said it was an out-of-round crankshaft vs. simply a bad seal itself.

Any thoughts?

If you get a real bad casting then you're in for multiple replacements, although PCA do seem to replace engines after a while, whereas the UK just have to keep going with new seals (and a 2 yr warranty :( )

A porsche mechanic told me it was not a rear main seal at fault in the older boxsters... this was secondary. The primary cause was the crankshaft, which fouled out the RMS.

how many over here needs rms problems multiple times and at what mileage and time.how much the average cost if you don't have warranty? hours and labor? thanks.
