Question about 1990 Nissan Maxima
How do I get the top part of the engine off so i can get to the injectors
Take off the plastic air duct then split the plenum ( that's the aluminum thing on top) this should be 10mm Allen screws. you will need a new gasket for the plenum. inside the plenum there are a few more screws to take off the lower portion of the plenum attached to the intake manifold. remove the lower plenum ( you will need a new gasket here too). Once here there are 4 more allen screws to remove the fuel rail. if you pull the injectors from the intake manifold you will need "O" ring gaskets and a drop of oil to reinstall.
here is a side note that will make your life allot easier: If it looks like it's in the way, remove it, because it is. This will save you hours in the end.
