4l V6 Engine Ticking

Hey guys!

I've noticed the past few days when the 4l V6 engine in my 05 (83k miles) is warmed up, it ticks pretty loud. The driver side ticks a lot more than the passenger side.

When I was in security, our mobile patrol (a '12 4l V6 Taco) developed a ticking sound similar to mine. The Toyota mechanics said that because it basically idled and only patrolled in first gear, "the lifters were bad" and Toyota ended up replacing the whole engine for us (after MULTIPLE times in the shop).

Back to my truck. Mine is starting to sound similar, but wanted to get everyone's opinions before I go on a wild goose chase. Is it a lifter issue? Is it normal?

Thanks!!!

Anyone?

 

Sounds like taco tick to me, they all do it to varying degrees. The tick is vacuum switching valve, which happens to be located on the driver side of the intake.

 

It's normal .. we call it the taco tic

 

that's a VSV ventilation valve ticking away, nothing to worry about but there is a write-up to place a washer and remove or reduce the ticking. Plus having a timing chain instead of belt ads to the noises... but it's not the valvetrain...
