Antwoord op "Timing belt on my 2002 Volkswagen Jetta"For future individuals who stumble onto this thread. The 1.8t is absolutely an interference engine. Very expensive and you will have some valves bent 100% of the time usually 80-100% of the valves being damaged. Head will likely need to be replaced not rebuilt if a timing belt breaks in the 1.8t. The 2.0 petrol is also interference but people sometimes get lucky and have no damage when a timing belt breaks. Most of the time they are also damaged.
