The only time I ever "flooded" an engine was after or while I was
driving through a deep puddle. Maybe a foot deep. The fresh air intake
for the Rabbit was under water so it sucked up a lot of water into the
cylinders. I removed the spark plugs and water sprayed out of the
cylinders as I ran the starter. I do not recall if I checked the
dipstick for water in the crankcase. In any event I sprayed about
100psi from the air compressor in to each cylinder, replaced the spark
plugs, started the car and tried not to drive in really deep puddles
again.
I am with the others that you need to check for clogged drains in the
cowl and the air intake. But in my case some water in the intake
pretty much just stayed in the intake, cylinders and out the exhaust.
Not much migration in the crankcase that I recall. That much water
also messes up an air filter. You should inspect your air filter for
clues and damage.
Are you sure you have dry gas in the tank?
If you do not have water bans can you turn on the hose to simulate a
heavy rain? Start by making sure the drains in the firewall work.
