Having problems with your 1996 Nissan Maxima ?
After car runs for a while it runs hot sounds like loose valves and car smokes oil on engine could it be a warped head?
Don't know how many miles on yours but it sounds like you may have multiple problems; possible bad valve cover gasket, failing oil pump (this can be checked with a pressure gauge pretty quickly) worn rings or one broken and worn valve guides and seals.\012Too many different chances for good diagnosis from a distance.\012If you have a high school near you, check with them for an automotive shop. Many will check for you free under guidance of an experienced instructor/mechanic.
