We've got an '82zx non that's starting to burn some oil ( 1/2 quart every 800). I don't have a lot of time to put into it, but can anyone give me resonable pros / cons on rebuild vs. purchase of rebuild. long block vs. short. Amount to expect to spend in each situation. I've always done my own work but never rebuilt a z's engin. I expect to stay stock. All other aspect of the car are fine. If purchase of rebuilt most resonable any recomendations in the Dallas area ? Thanks in advance.
