Rebuilt the 4.8L engine have codes and problems!

[nitrogass2000]

Ok i just put together the 4.8 X5 engine and it starts up but runs like crap.

I took it to Advanced Autoparts to run codes and this is what i get:


P0201
P0202
P0203
P0204

Also Maf/vaf code. which i cleaned it and its not helping. But i noticed that it DOES NOT have the grill on it for air disbursement and i wonder if that can do it?

And P0014 i think its the ignition is Advanced. I guess i did not set it correctly it was a pain to set the ignition or i guess its called timing, on this thing.

Also I got a code that says P0013.

Also, i read something about VCT the 4 Solenoid Valves that apparently have the ability to retard or advance the timing/ignition, and one of my codes i think says i have advanced timing and also the internet says that the cam sensor code maybe caused by these VCT solenoid valves so i am suspecting that because all 4 of them have the exact same plugs and i have no clue which one goes where, if one of you have the 4.8 can you look on your engine and tell me if the short ones go on the buttom or the top, or is it different on each side like i heard that the short plug goes on top on pass side and then on the driver side the short goes in to the buttom on the driver side? Help with this would be great, and the thing is i tried swaping them different ways but i think the computer may need resetting of some sort to recognize it?

ALSO ONE LAST STUPID QUESTION where is cylinder one and where is cylinder 8 i still cant figure this out! lol i am totally new to the x5. I am learning a ton.

Can some one help me out and tell me what these codes are and what they mean and what i could try?

Thank you
