3VZ-E Engine
The V6 with the head gasket reputation. Tune-up parts that fit, and the guides that explain the rest.
The 3.0-liter V6 has more power than the four and a well-documented head gasket history. A well-maintained one is a good engine. The parts here are the tune-up items that fit it — Denso cap and rotor, wires, OEM plugs, the intake pipe — and the guides cover everything from the head gasket question to the idle-up valve delete.

Questions
Is the head gasket problem real?
Yes. It's the engine's defining issue. A V6 with documented head gasket work is worth more than one without; the guides below explain how to tell which one you have.
Why delete the idle-up valve?
The power steering idle-up valve is a common failure that causes idle problems. The delete kit removes it cleanly.
