Need help with timing Chain

i have a 2004 4runner. long story as short as possible
blew the head gasket at 154K, doing research here seems like i got a little farther then most.

no big deal. bought a remanufactured motor because i didnt want to deal with the vvt and timing junk.

motor swap was as easy and a pontiac v8 in a firdbird with headers. no big deals once you figure out what you are doing.

swap went great. fire the new motor up and everything is great. get 30 miles on it and pop a check engine light.
p12 intake timing over retarded on bank one.

checked my oil control valve and replaced cam position sensor. no fix. take it to my brother shop and let their master mechanic check it out.

he says the cam isnt timed properly. and vvt etc is all good.

call motor place, after a month fighting the send a transport and tow it 300+ miles , from cali bay area to LA somewhere. month goes by and one expired reg ticket because they parked it on the street my car comes back.

they put 1 mile on it says its fixed.
30 miles later same thing.

goes back to my brother shop and they check all wiring and everything again and says if its not motor then there has to be something wrong with the ecu. $250 for a used comp and 330 to reflash and program keys later at the local dealership i get the same code.

getting really really pissed off now. it is october 4th, i swaped the motor dec5th 2012. see its kinda getting tired of this.

i am going into the motor to verify cam timing. does anyone have a run down on how to do this.

my brother is getting me the all data printout but real world experience would be great.

thanks

motor was a complete remanufactured motor. i bought a rebuilt because i didnt want to deal with the vvt timing etc. i am not familiar with it. what has to be removed to check the timing marks.

the company i got he motor from said he just pulled the covers and was able to tell from there. it this true or was he blowing smoke again.

thanks

Yeah they right pull the timing cover off and see if you are able to line up the tdc mark with the cam marks.
 
is there a step by step for this somewhere for this. i have read i need to pull the pan to accomplish gettin the timing housing off. is this true?
 
does anyone have a diagram of how the alignment marks are supoosed to be. i have the valve covers and intake off right now. tryin to find the marks on the intake cams and how they align with the exhaust cam.

going to start pulling rad and front cover soon

the car has a mis at idle, and is st 500rpm in gear. i cant imagine intake and exhaust both being off andnit still running "ok" was getting 20+mpg when i was driving it.

thank you all

okay i found a diagram with google and with the balancer at 0* ,all 4 cams check out in the correct position, could the actual vvt actuator on the bank one intake cam not be working properly. i have replaced the oil control valve and also cam position sensor.
also have checked and cleaned the oil control valve filter.

whatbelse could cause a p12?
 
Ok I have everything back together and running. I checked the ocv filter while I was in there. And switched out the ocv valve on the driver side with a new one I had purchased and dismissed as the problem.

The motor was rebuilt. I don't know how tight they were on tollerences and I don't have an oil pressure gauge but I put in 5-30 like the motor came with.

Could the oil be to thin causing problems with the vvt. Now I have to find my notes but for some reason I am thinking before the comp was replaced it was reading bank two as the problem.
 
Could it be the vvt controller on the front of the cam acting up and not working properly? Everything else has been checked and rechecked.
