Update :
I took the oil pan down today and there are no broken pieces of timing chain guides in there. I checked the chain from the oil filler hole and it looked tight and well placed as well. Tomorrow I will take a look at the tensioner as well as a cable I saw going down the engine (3 wires brown / green / white or gray) which looked a little exposed. Cheers, Ozzie

Have you checked the connectors to the DME ? Also if the M62 has the IVM voltage regulator like N62 has, that can cause your symptoms.

I noticed I somehow cross connected (Bank 1 -2)the O2 sensors and corrected them which did not make a difference. The car starts and runs without dying for 20 secs. After 20 secs, something in the engine starts working and seems to 'limit' things and that's when the engine dies unless I apply gas to keep it going. In that process if I apply extra gas to try to get higher rpm, I am noticing smoke starts to come from the back of the engine. Would the exhaust be blocked somewhere and it's smoke tries to come out of somewhere else from the engine? Meanwhile, I am still getting the 1-2-3-4 misfire and Bank 1 and 2 Camshaft sensor errors. Since I can keep the car running now, I can also get live data which I can video if you guys would be interested.. Thanks, Ozzie

My understanding is the car will not run without having CPS working. You are getting actual CPS error? What's the exact errors? I think the DME gives a lot of systems a "pass" during the first few seconds before it clamps down. You could simply be having a case of no clean signal from the CPS. Weird that the misfire errors only bank one. I would usually swap CPS in a case like this.
Save that, also make sure your connection to the DME are in good shape. Clean connectors and maybe continuity test to the sensors while you're in there. Also: back to the comment earlier: no coincidence: just like the O2 sensor swap, you may have missed some other important connector like say SAP valve or motor. That's on bank one side even though there is a crossover pipe to get sap to bank 2 look at all the wiring

Nothing wrong with your cam sensors. They are reporting that the timing is "Over-Advanced in Bank 1 and Bank 2. Since you didn't mess with the timing chain or vanos during this fiasco, we need to go back and look at what other thing you messed with. Th only thing that comes to mind is that the flywheel crank sensor is sending a signal to the DME that doesn't match with the cam sensors. You need to find a shop that has a scope and a technician that can perform a crank / cam correlation between the three sensors before throwing more time and money at this project.

No start after transmission repairs..
Over advanced often comes from lack of chain tension but usually only see that on bank one so ual is correct need to access what's up with crank position vs cam position. Is there a chance your aren't getting proper oil pressure? Are you getting chain rattle at start and does the oil light stay on longer than normal?
I would bring up real time requested vs actual on CPS anyhow just to see why DME is mad since everything is synced relative to the crank, that's a good place to start since you were down there maybe CKP or wiring to it got damaged?

FYI : 100% of the time I had "camshaft over advanced" on M62, it was AFTER doing timing chain guides and reset the timing and the cure was new CPS.
That doesn't necessarily increase the odds of that being the problem in your case.
