Its a Stock L28e with a 4 speed transmission

Hi guys this is my first 1977 Datsun 280z with a 4 speed transmission i having trouble with my L28e engine (everything is stock) cause some people say that it sound like it has a dead cylinder but other people say that it just an air leak somewhere I really don't know. The other problem is that when i try to use my turn signals one blinker work fine but the other one is just a solid light if you guys can help I'll appreciate it a lot thanks for reading my annoying problem.
