1986 bj74 3.4 turbo diesel wont turn of , well sorta....

[krawczuk]

hi, i have a 1986 bj74 3.4 turbo diesel , which has developed a weird problem.....
when i have my foot fully pressed down on the clutch and in neutral , then after i turned the key in the off position , the engine still keeps running on, BUT as soon as i let the clutch pedal come up say even 10 mm or so the engine will cut out , and also when i have my foot resting on the pedal , just enough to get the free play out then a LITTLE more the engine still wont turn off, as soon as i take me foot of- cuts out.
i`ve noticed there is a power booster type device on the clutch pedal , so i presume this is connected to the vacuum pump , and since the engine cut off is connected to a diapragm which in turn is connected to the inlet manifold , that there is POSSIBLY some sorta vacuum leak ???
any clues ?
