I have a 1998 s reg renault grand espace 2.2 rt-x dt thats a non runner, its my moms car she was driving to work when she noticed the oil light came on and the engine stalled so she dipped the clutch rolled to a hault and checked the dipstick and it showed that the oil was empty, so we towed it home put some oil in but the engine wont turn over, any ideas of what this could be or how to fix it or what it would need? thanks
