Looks like another 1kz-te cracked head

Pretty sure the head is cracked, loosing coolant, blowing bubbles in radiator.
Can anyone in Dunedin recommend a garage to use for head replacement?
Has anyone had experience with AMC branded heads, as opposed to toyota ones.

Buy a genuine head, use genuine yota coolant and thermostat. I've found it helps to block off the egr (and clean the crud out of the manifold while its apart), and reroute the pcv into a catch can. If yours is intercooled then clean all the oil out of the intercooler before it goes back together. May also want to check/rod/replace your radiator but absolutely test/re oil/replace your viscous fan.

I used a chinese head when mine went. symptoms were exactly the same. Yota head went at 160k its now done another 310k on the aftermarket one.

Thanks for the advise, will definitely look at checking/cleaning/replacing cooling system and block off egr.
Have heard it is hit and miss regarding chinese heads, would rather go with something more dependable. Have seen some positive comments regarding AMC heads, would be good to hear from anyone who was satisfied/dissatisfying with the product.
