I have a 3100, 2A82, and 2A87 code. Its resulted in low power and a rough-idle on start up but it goes away after 4 seconds after readjusting itself. Did you also have these symptoms?

I'd like to add that, perhaps in your case both your camshaft bearing ledges are to be replaced. I noticed from my searching, that when it was the exhaust bearing ledge that was to be replaced or people were having exhaust codes, people were having bad idles and rough running. If you did all the other troubleshooting already (Oil filter cage, VANOS solenoid, VANOS filter check valves) I'd check the camshaft ledges.

Just tighten them down evenly and make sure none of the rollers fall off the top of the cams. Only certain valves are up at top dead centre so you just ne

Hey gordon513, I had a bit of questions regarding the tray alignement.

I just put back in my exhaust cam now and unfortunately I can definitely feel the alignement isn't 100% with my fingernail. It catches going up on one side and catches going down on the other. Was yours really perfect? I'm this close to just say **** it and run it like this, the worse I can think of happening is needing a new ledge.

TIA!

Update. I finished the job. Ended up borrowing the C clamp special tools from someone and the alignement felt perfectu sing that.

Sorry to have missed this but glad you got the job done in the end. When I first tightened mine down I could feel it was slightly misaligned so I loosened off the bolts on the cylinders that were under tension and then tightened them back down in an 'equal' sequence - seemed to work for me. By the clamps were probably a better option!

Just figured I'd do another post here to confirm my issue is definitely resolved as well. Got my liscesne back and took it for a drive and did not get the code in the same way I drove before. Have a little bit of metal shaving in the filter though but I think it's just normal wear in, I will check again in ~ 500KM.
