Has anyone had to change a cam phaser I have the e51 with vq35de and the mechanic is stuck...
Have had the mechanic service the van,had a heap of codes changes both cam sensors crank sensor and vvt solenoid and alternator...motor still appears way over advanced hard to start and no power...not displaying any codes...could the cam.phasers be the problem?

Thankyou for time..
