Also , When I revmove the "Plum Intake" on top of the Engine ,do those bolts also need to be torqed?

you're using funny terms for these parts that I've never heard before ![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
All of the bolts are supposed to be torqued to spec. Particularly the upper intake manifold bolts [I think you're calling it a plum intake]. ![Over Here](https://www.clublexus.com/forums/images/smilies/overhere.gif)
Maybe you can find someone to help you and maybe you can find the FSM [hint: search]

its called an intake plenum, not plum...
the VCG job on the 1mz-fe is pretty easy if you just follow the factory service manual to a tee, and you take your time...be sure to properly seat the gasket in place and torque all bolts to the spec in the manual.
while your at it, change the spark plugs if needed because the rear bank is much easier with the intake plenum off.

Thanks for the Replys. Sorry for the Terms I used. I tried searching to find out the torqued specs but the search engine does not agree with me. Does anyone know the Torque specs for the Valve pan covers and Intake plenum ?

Here are the specs that I found. Remember that cleaning the mating surfaces is more important than the exact values that you torque these fasteners down. If you go a little deeper into the engine, the torque values then become much more important.

my two cents on the valve cover tightening... valve cover is 5 ft lbs... but going by feel is going to help more due to thread deterioation, dirt, and those rubber spacers.... remember to criss cross torque it...

Yeah, I was putting the head back on my Altima, and mistook the camshaft saddle torques - it said 15 - but it was IN/LBS, not FT/LBS - snapped one off, and then I double checked the torque specs!!!
