Hi All,

Does anyone have a diagram, parts list, or just know what the bolt sizes and bolt grades are for the upper and lower intake manifold and valve covers on the VG33E engine?

I am planning on replacing the knock sensor and leaky valve cover gaskets on the 2003 Xterra XE and would also like to replace the hardware while I am doing the job. I have snapped a bolt on a valve cover and have had rusty bolt issues in the past and just don't want to repeat re-using old hardware.

I have also been looking in the"Engine Mechanical" section of the service manual and on nissanparts.com but only get bolt lengths and part numbers, not the actual sizes. Any other sources I should look at? Thanks!
