All "IMS failures" are not IMS failures! Carnage within!

It does appear that the unit was overloaded, but all the up stream components that actuate it were in fine condition..

It appears that the tensioner wear pad may have worn and then been ripped off and that created the tensioner to operate at an odd angle that could have made it break..

An oil sample could seek out the wear materials from the tensioner pad in the oil and then if the chain is going metal on metal before a failure the elements of the tensioner would be in the oil as well..

Its a long shot, but we are already observing so many oil samples its just one more thing to add during analysis.

The newer tensioner being thinner with the plastic contact patch doesn't help anything.

Jake, you are the Stephen Hawking (who could explain concept of black hole to common man) of M96. Thank you for your time effort in diagnose these engine. I have 2001 Boxster S and it is right at 43k miles mark. I am holding my breath now. :-)

Don't be afraid.. Just drive it. If it breaks, then deal with it.
A lot of these engines fail, but a lot more don't...

Thanks for the info. Too bad its not going be to an easy DYI preventative project for most guys, but its good to know that when and if it needs to be rebuilt, then it will be 'better than new'.

Until that time comes, as Jake said, just drive and enjoy the damn thing.

Not to worry Jake, your advice from Excellent magazine article helps. I do drive my Box year-round even at -35C here in Canadian winter. I guess if it breaks, I will be talking to you for a new engine. :-) Cheers and thanks again.

Now that's the right attitude!
Jake maybe I missed it but was this off a trip or a manal trans?

Jake, I don't think they use gavels all that much in suits, but maybe Lovebunny can weigh in on that one.
