Toyota Previa JDM engine running! Noise? Lifters or Exhaust?

[Kurtanius21]

Hey guys, my JDM is running and performing well? Is this valve tappet sound, or exhaust leak? I know I have an exhaust leak, but I don't know if that is causing the noise or not.

Hey guys. I found out what the noise is. It's not the lifters. I measured every one. They are all in spec.

The noise is a ticking fuel injector. I realized the ticking stops whenever I let go of the gas while in gear. Not a major problem at all! Case closed!

Outstanding.

Yeah, not only that. The ticking has resolved itself. No more ticking at all. Fuel injectors have been sitting for 20 years. Just had to be freed up!
