VVT on L99, or what?

Thats good to know-I'm still concerned about it's complexity. I've learned that the more complex an engine or transmission is the more it costs to fix it or deal with it. I apologize because I'm old school-the technology in the new cars both amazes me and confuses me. It's incredible what they've done with both engines/transmissions and engine management; but you can't seem to even open the hood of new cars without an engineering degree lol.

They days of carbs, distributors, big fans and 100 belts is truly over, huh?

Seriously, though -- THIS AFM isn't too complex. I suspect the original system that debuted in the Caddillac was mechanically activated. This one is computer controlled. The mechanical parts consist primarily of de-ac lifters (collapsable lifters), and an piece that sits in the valley (called the LOMA, or Lifter Oil Manifold Assembly) that controls oil-flow to the lifters. If it does go bad (which is very rare in this version), as somebody already mentioned - it keeps itself in V8 mode until you can get it checked out.

I was gonna say, fuel injectors are way easier to play with than carbs, basically all fuel injectors are is jets that spray directly onto the back of the valves. With carbs you're always in danger of one slip that sends all the little springs clips and other parts everywhere.
