Click and Clack at it again - De-carbonizing an engine.

[roccaas]

This guy puts his Blazer hood first into a Florida pond. No water gets into the cylinders. Mechanic checks everything over, replaces some electrical parts, and the truck runs MUCH smoother than before the half drowning.

Tom and Ray feel that there was enough moisture in the intake manifold to de-carbonize the engine, hence smoother running (who knew??). They admit to introducing water by a vacuum hose (off the carb?) into engines to take out the carbon.

Now there is a machine they can upsell to clean your engine, so they don't do the water thing anymore.

Two questions:

1. How much water, where and how introduced to rid the A of carbon?

2. Does this have anything to do with the thread some 2 years ago on FB about how much smoother a car runs after a rainstorm? (I thought we'd decided on denser air providing better combustion?)

First Carb icing, now de-carbonizing with H2O!
