GOtcha, please share more pics! the Boxster is seemingly in a class by itself with everyone else fighting for 2nd place. Lovely vehicle!

(My last Boxster was an S, plenty of smooth power, superb steering and handling and braking like no other car.)

Thanks for the clarification, therefore 09/10 has DI and no intermediate shaft.
Although that doesn't really change the statement, "Fortunately it seems the last of these failures was prior to model year 2010, if that's any reassurance."

I read that the early-build '06s were the last to have the weak intermediate shaft. A beefier IMS design was introduced and failures still occurred after, but much less frequently.
I believe even at '09 and newer, only the S models have DI and therefore here in 2010 the base Boxster and Cayman engines still have an intermediate shaft.
And guess why I've been looking into this problem...

As alot of people know Boxster was created to increase Porsche sales volume using interchangable parts with that other car they make. Heads, camshafts, rods & crankshaft of the 3.2 are identical to 911's 3.4 of the same year, so basically if you install bigger pistons you equal 911 power curve.

My trouble is that the 2005 normal Boxsters are now entering my price range these days, and as far as I could tell, they made numerous improvements on that generation verses the original, including a more modern interior. Whether or not that makes it worth extra couple of thousand is still up in the air.

To avoid the possibility entirely, you're safe buying a 997.1 with 3.8L engine, which is 2006 and newer. 2009 and newer are 997.2's, and are DI engines. Check out rennlist if you want the poop on Porsche's. And if you're thinking about buying a Porsche, all i can say is do it. Awesome cars.

IMS bearing disassembled
I tried to remove the grease seal from the IMS bearing with this small pick & unknowingly caught the bearing race also. The race was loose enough to come apart very easily & the BB sized ball bearings were now loose inside the IMS shaft which is a hollow tube. Conclusion: This bearing had excessive freeplay & I guess it would have come apart within 5,000 miles. This engine has 88,500 miles & has had Mobil 1 0-40 oil & filter changes every 7,000-8000 miles twice as often as Porsche recommends & with the approved Oil.

yeah I was shocked at how small the ball bearings are in this first of 3 designs. I'm not sure about the oil though, several professionals have said that when BP bought Mobil they reformulated Mobil 1 (watered down). Most of these people recommend Castrol which is approved by Porsche also. I changed to Castrol Extra synthetic for all my cars. So glad I pulled the engine when I did.
