Well I been talking to a few repair shops and I am getting mixed opinions and suggestions. Please keep in mind that I am not going to race or boost this car. As for as the re torque of the heads I get mixed opinions as well. I am getting confused.
1. One shop tells me to drive the car till it blows the head gasket and if I am careful not to overheat the engine it might never blow the gasket. Sounds like a cheap option but blowing a gasket sounds like I could cause more damage than necessary and make for a costly repair.
2. Shop number two tells me even if I am proactive and repair the HG with a metal one I will still be no better off. They claim that the cooling system is to fault for the HG blowouts and the alloys in the engine cause the HG to fail regardless of the HG used. They feel that the 7mgte just never was quite right. Toyota missed the mark and the Bullet proof performance was never achieved.
3. Shop number three goes along the same thinking as shop 2 above and suggest replacing the engine with a 1jz-gte. Shop number 3 owns two supras and shows and races them.
