I am interested in testing how waterproof the snorkel installation is on my Paj.
If a large plastic bag was put over the top of the snorkel, and the running engine stopped, this would imply that the snorkel installation is air tight, and therefore it would be reasonable to assume it would be water tight.
If the engine dropped revs and struggled to run normally, this would indicate an air leak in the snorkle system, but would this mean the installation might or might not be water tight?![Dunno[1]](https://www.pajeroforum.com.au/core/smilies/0/0/5/4/3/6/images/smilies/dunno[1].gif)
If sealing the snorkle head resulted in no change to a running engine, does this mean there is a big air leak, and that it is unlikely to be watertight?
Many snorkles also have a drain facility to allow rain water to drain out of the snorkle - does this provide an alternate air path into the engine, if you blocked off the main intake?
Has anyone done any testing along these lines? How would you test to ensure your snorkle does not allow water into the engine without parking in some deep water and exposing the engine to potentially expensive damage?
