...Alright, give it to me straight Doctor... I heard the infamous "BOOM" associated with a broken timing belt and the symptoms that come with it yesterday while on the freeway. Got it towed home, instead of the dealership (confident with all the work on my 1999 GS400; 150k on 1uzfe). Given that it's an interference engine, should I even bother with changing the TB? How do I know/check/tell if the pistons damaged the valves at all? Any advise as to where I should start, prior to shelling out $500 for this job? Thanks for the help guys! ~Kay
