Howdy. My problem was the upper timing case covers were not flush with the top of the cylinder heads. Once I purchased the BMW "profile gasket tool" which is just a valve cover gasket made of flat plastic and also switched to genuine BMW upper timing cover gaskets, I pressed down on the upper timing case covers while torquing the six hex bolts onto the head. This tightened them in the proper position. A few millimeters off and you will get an incorrect timing code. When going through this, I wasn't sure if the impulse wheels were bent or not (they were not), and ended up buying new wheels to install. I also proactively rebuilt both my Vanos transmissions with Beisan kits, so unsure if those could be causing an issue if they're sticky or not. You also need to have a code reader to reset your engine adaptions and then the system can relearn everything once you've completed the job. I used the iLand for that, from Atlantic British. Hope this helps.

@@mjrgroup Thanks for the reply, much appreciated! I’ll try the adaptations reset first and see if that helps. The guy who did the work is really good so even if the code reset doesn’t work, he’ll be ok digging back into the engine. Sounds like it doesn’t take much to upset these engines. Thanks again - Jon 👍
Awesome! I’m in the middle of rebuild from the heads up including timing guides 👍🏼
Thanks for showing ❤ mine sounds the same so I guess we good
Wow this sounds amazing
What was the engine rough idle fix
How did you resolve the rough idle? I have this on mine after new timing guides.

How much was the rebuild
