the new phasers are vastly different then the old style i have had mine on for 2 years and 35k with no prob. you did not get the timing correct, you did get the timing alignment tool didn't you. sounds to me like you got one side or the other out some how ditch those pos lock outs.

Yes, I have the crank tool, I bought all the specialty tools. I also have video proof verifying mechanical timing, all timing marks lined up. Also had another person check as well to just to be sure.

 

Well, sounds to me like you succeeded. They're not knocking!!

As for diagnosing what the problem actually is - If you temporarily ditched the lockout 'tune' and went back to 'stock', I believe you could use Torque Pro and the dashboard posted here:

to get an idea if chain timing is correct or not. At 'idle' - NO retard is ever requested - being the same position they are 'locked' into, so (although I have never tried/tested this theory), It seems to me if cam timing is off it should show up in "CAM ERROR". It being simply the difference between PCM REquested Retard and actual positioning of the cam phaser.

Same would be true if Cam Retard is requested, the Error should reflect the -positive or negative- difference between Requested and actual, ie OVER ADVANCED with lockouts in place.

This approach might require you to purchase the $4.95 Torque Pro App, and a $25.00 Bluetooth dongle. Possibly an old used or discarded Android phone or Tablet if you don't have one or can't borrow one.

Other than this - I know of no way to verify chain timing other than another tear down.

 

Could it be the CAM position sensor isn't seeing the position or failed some how? When the dealer did the timing job on mine, I got about 10 miles out, made a stop and when I restarted the check engine light came on. It was running like it had a slight miss to it. Took it back and they found that one of the tabs on the phasers was slightly bent. Thus the sensor was only seeing 2 of the 3 tabs. They bent it into place and never an issue since. Maybe one of the tabs is bent out of place.

Just a thought.

 

I would think it 'could' be, but that should produce a code - (P34x ). The PCM 'polls' the cam position sensors at the appropriate time window when the cams are _supposed_ to be in the appropriate position. If it doesn't see it at all should give a P0340 or P0345, If it's intermittent, a P0344 or P0349.

Of course - its a good thought. Bent phaser fingers is certainly a subtle condition that will definitely cause problems. A lot goes on in the PCM that none of us can imagine when it comes to defaulting tables and calculations trying to handle a fault condition.

 

Could be...at first I had a P0345 code being thrown, tried cleaning the sensor plug, putting the plug on a multimeter to check for shorts. Even changed the sensor in a last hope that would fix it. I spun the phasers around before installing chains to check if they run true, and they did, but maybe the tabs got hit by a valve cover and got bent...hmmmm.

 

Again, I put it back to stock and it still is shaking, missing, and smells rich.

How did you do that? Were ALL the roller/followers out?
