Should I Change Head Gasket? - Toyota Yaris Forums

WeeYari · 03-10-2015, 04:38 PM

The 1NZ is a naturally noisy engine. Mine has always had taps and rattles which used to lead me to believe I had valve and chain issues. That is until I learned on this forum that these noises are normal. Had gotten used to the silence of a timing belt.

I concur, my 2012 Yaris' engine was noisy brand new and still sounds the same. Toyota tech at dealership said it sounds perfectly fine.

The head bolts for the Echo require a double hex bit. It looks like a T-5 Torx bit but is not. Snap-On sells the proper bit (8 mm, I think but it's best to check).

If you choose to do the head get the proper tool.

I am assuming the Yaris uses the same head bolts.
