Thanks for documenting this. I am about to dig into the valve seals myself. I have all the tools, just need to find a few days to spare.
Let us know if you hit any snags. I know there are some great videos out there. I am curious how you deal with the intake cam springs, the 2 long videos on Youtube each do it differently.
Good Luck!!

When I bought this car 2 years ago, I replaced valve cover gasket, and the internals look the same as now, so it could be the previous owner who wasn't on top of oil changes.

Installed flywheel locking pin and cam timing locking tool
Removed intake side Vanos
Removed timing chain tensioner
Removed serpentine belt
Removed crank pulley
Removed engine mount and support bar
Removed friction wheel and belt tensioner
Removed top chain guide
Removed 2 cam gears
Removed 3 tensioner guide pins
Removed timing chain and guide -> the car ran fine before, but VERY surprise to find the guides were broken already. I was really running on borrowed time.

No kidding. Totally didn't expect that. The car ran fine prior to removal. It was on its last leg.

Day 4.
Replaced valve stem seals
Installed eccentric shaft and camshafts
Installed cam timing locking tool
Installed new timing chain
Everything went pretty smooth. All screws are hand tightened for now because found that my torque wrench only goes down to 20NM.
Ordered new torque wrench from Amazon.

Actually. Not bad at all. The first one is always tricky, but after that, quickly learned how to do it.
The tool I used.
And this is how I did.
Also used this youtube video.

I saw few videos on how to use the spring tool, and looked very complicate. Now I've done it, definitely think the modified screwdriver method is easier and quicker.

Day 6.
Install U brace/support
Fill the coolant -> was drained because I had to replaced a coolant pipe.
Reset variable valve timing adaptation
Knock on wood and fire her up.
YES. She is running well and NO CEL. Fxxk YEAH!
I'll drive her around for a couple of weeks and change the oil.
Here is the video of her running!

I'm so glad it's all finished without any major hiccups.
I've been driving last couple of days and noticed the engine sound have changed. It could be placebo, but sounds more smooth.

R56 timing chain advice wanted
I've got a 2012 R56 Mini Cooper (not turbo) with about 90,000 miles on it. I've been told by my local mechanic that I ought to be thinking about replacing the timing chain. Does anyone have any advice as to what's typically accepted as the recommended mileage for this maintenance?
TIA
