148-horsepower 1.8L I4 6-speed manual FWD

13020 mi I had the dealer inspect a loud ticking from the top of the engine. It sounded like a valve that was out of adjustment, its a single prominent consistent loud click that changes with engine speed. They said it was a fuel injector - normal.

22320 mi Still ticking from the cylindet head, brought in a 3rd and last time, they said it was fuel injectors. (I disconnected each injector one at a time and the ticming was still there) I think its a lack of oil supply problem to the valvetraon. Now waiting for the engine to seize as Hyundai is replacing engine blocks on the 1.8's as they fail. Stick with Honda or Toyota.
