[DML] Re: vacuum leaks

["content22207" <brobertson@xxxxxxxxxxxx>]

I suffered a similar failure in the hard plastic line under the
console to the HVAC mode switch. Totally barbeque'd the driver's side
plugs (passenger side intake rail feeds driver's side cylinders).
There's a pic in #5939's photo album. I'm lucky the pistons weren't
damaged.

are a lot of places for it to leak, some of them obscure.  I talked
recently with a shop that had done what I considered to be an
extraordinary job of finding a hole in the system.  By clamping of
hoses, they had traced their rough idle to a crack in the rigid vacuum
line running forward from the right side of the engine to the front of
the car to feed the brake booster.

vacuum puts the power into the power brakes and pulls the flaps that
direct hot and cold air from the dash.  The hot water valve is
modulated by vacuum.  All of these places are potential trouble spots
whose only noticeable effect is on engine performance.
