Nissan Primera P12 2.2 diesel vacuum pump

 

I am new to nissan cars and obviously new to this excellently supported forum. I recently purchase what i thought initially was agood value 2002 primera 2.2 diesel. after a week i noticed noise from top right hand side of engine, soon after on way home from work i lost my brakes, anyways it turned out to be vacuum pump. i had to purhcase a secondhand pump and a further kit. however when the mechanic put the pump in, jacked up the car, turned the front wheel, he noticed that wheel and subsequent engine came to a halt. now he has to further strip the engine. anyone any ideas ?

 

the car was driving ok in  morning except for noise from pump. on way home brake pedal went hard and was of no use. no further noise or any warning lights were apparent. left it then at garage who confirmed vacuum pump had completely failed. and as he was checking out things with the changed pump without starting the car and using the front wheel with the car in 6th gear he noticed that on rotating the wheel, it then came to a stop. he suspects that the some chain may have skipped a cog and changed the timing, indicating as he think that perhaps timing chain & tensioner etc may have to be replaced. 

 

 

car wasnt started at all, thats why i gather fron wheel was rotated, although when he removed the vacuum pump again and rotated wheel, it hit stop. probably as suggested that skipped cog!
