I'm following this thread with great interest, as I am attempting to gear myself up to do it, as well.
2 questions, if you don't mind responding.
If I understand correctly, you want the engine at #1 TDC prior to tear down. This would be indicated by the keyway on the crankshaft being at the 6:00 position, and in this position the timing marks on the cam sprockets and the chain guides should be aligned with the colored links on the timing chains. From this position, you can install the camshaft locking bars and the flywheel lock and proceed with tear down and then reassemble with new chains with colored links again aligned with cam sprocket and chain guide timing marks and engine should be in proper time upon reassembly.
Question 1.
As indicated in your first post, there is not an index mark on the crank pulley. Can you set the crankshaft keyway to 6:00 after removing the crank pulley by threading the crank bolt back in after pulley removal and then using that bolt to rotate the crank/engine to the keyway at 6:00 position with the transmission in neutral?
Question 2.
Am I understanding your most recent post correctly in that you are finding there is enough chain slack to replace the timing chains without removing the sprockets/vvt units from the camshafts?
ETA: Question 3. Are there timing marks on both both camshafts on each bank? Looking at the service manual, it doesn't appear to show them. It looks like there are marks on the exhaust cam on bank 1, and the intake cam on bank 2.
Thanks. You have my vote for thread of the year so far.
