years and never had problems except the normal maintence (timing belts, oil changes, etc). It has over 273K miles. I also have a TT that I pulled the engine in the first two weeks of owning it and took about 1.5 years for the rebuild. After 5K miles the TT has a knock in the motor at 2500RPM. It is a fully built bottom end also. I always seem to be tracking down boost leaks also.
