PVC is first primed (both contact areas) and then cement is applied, again to both areas. The primer slightly softens the PVC, enabling the glue to do a better job. I would guess that any odor at all would dissipate rather quickly, but I really don't know where that specific "diesel" odor would come from. PVC is pretty much the standard now (where copper pipes were used before), so there is a lot of primer/cement used in homes and commercial property. By the way, PEX piping is now being used more and more often. Though more expensive than PVC, when water freezes in a PEX pipe, the pipe expands and does not burst. That's what was installed in my new solarium.
