Jake, if this "sticky lifter" issue afflicts nearly all M96 engines why haven't we seen more posts/discussions on this topic? Do the 996 engines have the same issue with the lifters? Is it just me, or does this seem to coming out of left field?

You need to understand that these methods are so temporary that they pose little (if any) risk.
We're not talking about running the engine thousands, or even hundreds of miles with these 'cleaners' in the motor. Setting up to do the clean and running the car 30 min. @ 60mph means you're putting 30 mi. on the car - that's all.
And, ATF is generally better quality base oil to begin with because it has to last much longer in a tranny. It's advantage is that it is chock full of detergents/dispersants designed to keep the numerous small checkball valves and such in a tranny clean and is of a lower viscosity and so can penetrate areas your motor oil cannot. Also, realize that with the Boxster, you would be effectively diluting it 8:1. I wouldn't hesitate to add it to my engine in those circumstances, even with Jake's caveat about variocam solenoids, in fact I'll be doing just that this fall a month to two weeks prior to seasonal storage so I can do my final oil change just prior to hybernating it for the winter. An auto trans contains solenoids too (the tiptronic surely does), and it's made of the same materials as the variocam solenoids, yet it survives a 'lifetime' being bathed in ATF, not merely 30 min. I share the same degree of concern as Jake for longterm effects to the internals, but not if used under the guidelines I previously described.
30 minutes! That's it, then a full flush, and then another within 500 - 1000 mi. as a safeguard.
Be aware, I'm not promoting this, people have to decide on their own if it's worth it or not for their own car. I'm just pointing out that this method is not new and has worked successfully for years on many types of engines and it does clean up sticky lifters. According to the experts, your M96 engine is gonna grenade sooner or later anyway, from any number of possible causes, so how large is the risk really?
