if you dont know how an EGR valve looks like, look at the picture, the arrow in the image is pointing to the egr.

i have a 1996 nissan 300zx non turbo and the location of the EGR is behind the engine.

out of all the cars i have own, this is the hardest place where the EGR is located.

to remove and install the egr is simple, but on the 300zx is a very difficult task.

removing it is not as hard a installing it. to replace one takes alot of time and patience.

so to remove it, i had to remove the top intake manifold. once the manifold was removed i can reach the two screws in the back that bolted to the intake manifold.

once i have it removed, it gets more harder to put it back, i had to use a puller to align the holes so i can thread it back it.
