[DML] Re: #1 cylinder problems

["content22207" <brobertson@xxxxxxxxxxxx>]

"Blowby" goes the other way -- from the cylinders into the crankcase.
Is what causes oil to get pushed backwards into the air filter when a
PCV valve is stopped up (intake suction also contributes).

Atomized fuel will indeed coalesce in a dead cylinder and run down the
walls. Rings are not tight enough to hold a low viscosity substance
like gasoline. Plus they are not solid the entire way around (are gaps
in each one).

Didn't steve say the plugs were carbon fouled, not oil fouled? Even if
they were oil fouled, problem would most likely be disintegrated valve
seals, not rings.
