Winter maintenance project 4.6is

I have reset the timing today. I have done following
1: lock engine at tdc, aligned camshafts with the camshaft lockingblocks
2: unlock everything, spin crankshaft with a ratchet 1 full turn so that the marks on camshafts face up again, re-check camshaft positioning, adjust what is out of time.
3. Rotated the engine once more, this time all camshafts aligned perfectly! intake cams on both banks are fully retarded to the left when i check the realigment.
4. When i released the chaintensioner to put the upper covers on, i noticed there was some slack between bank 1 and 2 cam sprockets (around the U-guide) that goes away if i gently pry the tensioner guide piece, is that the way it supposed to be? I have put the valve covers on and soon be ready for startup again 😄

Started the car today, no more water leaks, engine sounds really good. But i still end up with the p0022 code. What is going on?!? The only thing suspicious ive noticed is that the inspection holes on the upper timing covers doesn line up with the holes on the sensor wheels. Shouldnt those line up since the cam positioning sensor mounts in the upper covers? I have used the timing jigs when tightening them down. I have made a little video of live readings from my icarsoft, if it helps. This car is soon gonna make a nice playhouse for the kids in the backyard!

From my experience, you should make sure that the timing wheels line up with the holes in the timing cover, since that's what the sensors measure. Unfortunately, the timing jigs are not always accurate. Back when I was using the old BMW-style timing wheel jigs, I always had camshaft timing error codes and I would have to tweak the timing wheels afterwards. Now that I've switched to using the GAS timing tools, I've gotten the timing spot on with the first try.

I have the bmw style timing tools, im going to swap the cam positioning sensor between bank 1/2 to see if the code switch side. If that doesnt work, im going to set the sensor wheels by the holes in the upper covers. Thx for reply

Adjusted bank 2 sensorwheel today, now it alignes with the inspectionhole in the upper timing cover. But still throwing code p0022. What a nightmare this has become

Guess what, went out in the garage a bit frustrated about the error code. Took out the electronic degreaser can and sprayed the connections on solenoids and camshaft sensors, wiggled them in and out a few times. Hooked in the code reader, reseted the adaption values for the ecu, cleared the p0022 code. Started up the engine and read the trouble codes one more time. The code is GONE!! Happyface atm

Now that the engine runs great without any faultcodes, i have done some of the other things mentioned in my first post. Here are the rear brakes painted.

Passed the yearly car inspection this monday, so now the car is on the road again, and she does run fine! Thx for all the help under the chain and guide swap!
