Long story short.....Leaking coolant , dealer says head gasket gone, there would be a possibility bolts would strip upon removal. if they did strip it would mean replacing with a new short block $6500 + or used engine $4000 vicinity. bolts did strip during removal . I've decided to go with used engine 20K . I'm not impressed, this is one of the nicest cars I have ever owned but it sure leaves me wondering if I'll ever own another Toyota. We'll see after I have the final bill and chat with Toyota as the dealer has already told me there was nothing they could do for me
