Sorry to hear... Can you tell which bank threw the code?

Bank 1-3 unfortunately.

Have you checked your oil filter? That may tell a bit more about the issue. Keep us posted!

Unfortunately I changed the oil a week before I found this discussion. I am pretty sure the “rattling” is becoming louder Tho, when starting the car cold. Once it’s started it runs well and subsequent starts are normal.

I am not clear on the work to replace these 0-rings and the actuator. Is this something a competent shop can do with the engine in the car? Is this a $3k repair or $6k?

Just to make sure your actuator is failing, I would still pull the the filter and cut it apart to see if you have similar green rubber debris to that of shown in several threads in this forum. I believe the replacement can be done with the engine in the car, it`s difficult though because of the limited room. It`s quite straigthtforward with the engine out of the car on a stand if you have the right tools. No clue how much the labor costs, the actuator unit is around $1000 new.

Ok, I don’t get this. Just received my new OBDII scanner yesterday. I cleared the 3141 error code (Camshaft Adjustment Bank1 below limit value) that threw the CEL. I cleared the code with the engine running. The moment the CEL cleared, the engine idled down maybe a hundred rpm. In addition, when I start the car after the CEL was cleared, the car does not really “rattle” the 1st second or two after starting as it had. Other than this anomaly, it runs normally otherwise.

Why does the car start and idle differently with the CEL on than off? Why would the chain “rattle” be different? Is that the nature of the 3141 code?

Sounds interesting. What I can think of is that your solenoid got stuck in one position and clearing the code made it go back to where it should be at low rpms. But i`m just guessing. Did the CEL come back? You may wanna ask this question in a separate thread, perhaps more folks will chime in with knowledge about these error codes.
