Adamc Posted September 22, 2019 Share Posted September 22, 2019 Hey , I'm having intake vct issues, it's very noisey and rattling at revs below 2600rpm. I have checked everything, even pulled motor out and changed all timing gear and oil pump, had vernier cam gears and still had the noise. I'm getting 14v at the plug but when supplying a constant voltage from a battery source (I have tried 9v and 12v) noise completely goes. I'm about to get car tuned with pcm tec but been putting it off due to the noise. Uploaded a pic of what the vct is doing at idle Any help would be great cheers https://photos.app.goo.gl/BEJfkRTdnHcXpygU7 Quote Link to comment Share on other sites More sharing options...
Adamc Posted September 22, 2019 Author Share Posted September 22, 2019 (edited) *** should note this was a new (54,000kms) motor after I had a harmonic balancer destroy itself and wrecked the crank and bent valves in my original motor. Motor has made the noise since being installed. Edited September 22, 2019 by Adamc Quote Link to comment Share on other sites More sharing options...

Motor has made the noise since being installed. Going to go with you have a problem with the actuator. Datalog the camshaft position vs requested position (eg the position error). Also check for DTC codes relating to the VCT sensor. Quote Link to comment Share on other sites More sharing options...
