Here's a new idea to get to the dive site!

It seems pretty plausible, though I would think you'd have to run the crankcase and transaxle vent up the snorkel as well.  Perhaps they tapped them into the intake snorkel?  I'm guessing longevity wouldn't very good though, as the shaft seals and other sealing components of an automotive engine are mainly designed to keep oil in, rather than pressurized water out, so you'd end up with water in your oil. The Lada probably has no electronics to speak of, so there's nothing else to ruin (well, aside from every suspension joint and metal component in the vehicle).  Very cool!
