IMS article
The latest copy of Excellence magazine has a two part article (first part in this June issue, part two in July I suppose) concerning the M96 IMS failures and fixes by Tony Callas and Tom Prine. There will be input from Charles Navarro of LN and probably by Jake Raby in the July issue. Good to know the topic is still alive and more fixes etc. are on the way down the pike. Check them out.

Allen,
What is the date is this issue so I can order a copy. Does This article give info on other fixes? As far as I know there is only L and N.

As per my message: JUNE issue has part 1 and I imagine JULY issue will have part two with the information you are interested in.

Tony and Tom did a great job on the article with a ton of research going into it's composition. They made lots of contact with Charles and I and just a few minutes ago I did a quick review of the second part.
Should open people's eyes further, for sure.

For what it's worth, this years Consumer Reports listed used Boxsters ('97 to present) as models to look for

Thanks for the heads up.
I had a look at the article and found it to be excellent; very comprehensive and detailed with a good frame of reference....great job Charles and Jake! I dont know too much about the M96 and always had though I had a three chain set-up but I have five!!!(2000 3.2).
Which chain arrangement has been found to be superior? I would guess at the three, but there are certainly a lot of chain guides and tensioners if I recall the schematic correctly...

The article commented on the positive effect of high pressure loading on the IMS bearings due to elastohydrodynamic effect. First time I recall reading that.
IIRC the failures were thought to be more frequent in lightly driven cars. Maybe this explains why. Or maybe frequent track-type loading is required?

I has read the article and I was stuck! But sometime it could be happened.It was high pressure on IMS bearing so it has fast oil pressure while driving on the road.So if you has to see long drive.It could be better for you.

FYI- Oil is not delivered to the IMS bearing via pressure at all.. what causes the seal to break down and fail is high oil temperatures.

Thank's Jake - you are correct.
I don't know what I was thinking about, must be the old age brain fade happening (again)
