Best Answer

I had my Lexus GS300 timing belt replaced by dealer at 110K miles including a new head gasket. After three years at 145K the head gasket was blown, and it's obviously the dealer didn't do a good job to install and torqued it properly. Defective head. Never torqued properly at installation. Ran the car for a long period of time with little or no coolant/oil.
