My dad bought a 99 mk3 jetta with a broken timing belt. I put a new belt on it but when I align the TDC marks on the balancer and lower case the #1 cyl in at BDC not TDC. If I align the #1 cyl to TDC the timing mark is on the bottom of the balancer. What could cause this. If anyone has any ideas please let me know. All my yrs of auto repair I have never seen this.
