Ever since the dealer recommended replacing the timing belt… “before something catastrophic happens” I have been trying to get one simple answer. Does this car have an interference engine or non-interference engine. The Lexus mechanic couldn’t (or perhaps would 't) give a straight answer to this question. He only eluded to the fact that if the belt was to break the piston “may” come into contact with the valves and the engine would be toast. I have done the obligatory web searching and have found that everyone under the sun has a different answer for this. Does anyone out there have a clue?
