Yes, I've heard about the oil line failures, but I haven't been able to find a line fitting the description. I'm a new owner of a used 2007 ES 350 with 70,500 miles and it appears to be in excellent condition. But I want to prevent any problems, such as destruction of the engine by oil loss! So, where is this oil line? I have searched all around the engine and don't find any lines that appear to be oil lines. Is it possible my vehicle doesn't have it? If so, what options are required to have an engine oil cooler? The only visible oil lines go to the radiator for the transmission oil cooler, and they return to the transmission. Thank you for your assistance, Santaklos
