01' Nissan Xterra. - Suddenly just hours after shop replaced valve cover gaskets! Have been having some oil leak issues and shop determined it was most likely valve cover gaskets needed replacing.
Yesterday they did so and confirmed they were bad upon inspection so they were definitely the problem. Picked it up at 5 and drove it home perfect. No more smoke from dripping oil! Went out to crank it again a couple hours later and it wouldn't crank at all. Turned over a little but barely.
It finally cranked but idling very low, wanting to shut off and engine sounds horrible suddenly! Knocking etc. This problem was non-existent until the repair. Could something have happened during gasket replacement to cause this?
