These guys are a specialist at fitting LN bearing upgrade.

there are about 5 common reasons for engine failure and IMSB is just one of then.
They have only seen one IMSB fail in the last year, yet many others with cracked cylinder heads, or broken timing belts etc.
What I got from this conversation is that, yes, the IMSB can fail, gut it's just as likely something else will fail too.
My car is worth about £5K - the upgrade will cost around £1K. So it's all a gamble of course.
My oil is clean so I'll take the risk
This of course is always a heated subject, but the phone call did open my eyes to other engine problems that seem to get forgotten.
has IMSB failures overshadowed other reasons for engine failures?

The Boxsters in the UK have timing belts? You should change those every 100,000 miles.
