Lexus Engine Ticking Noise
I have a 2011 Lexus GS 350 RWD with the 3.5L V6 engine (2GR-FSE), automatic transmission, with about 82K miles on it and no codes. However, I've noticed that it makes this pretty loud ticking-like noise from only one side of the engine though. See the link below to hear the noise, I've read that it may be the fuel injectors- since this engine has direct and port injectors.
What do you think it is, should I worry?
