I'm in the process of replacing the timing belt on a 1991 Lexus LS400, and I noticed the timing marks are way off - When the timing marks on the cams are lined up, the crank is off by a good 90 degrees - when I first lined up the crank to 0, the cam marks were off by 10-20 degrees, and I rotated the crank to double check and they are off now. Now, the 1UZ-FE for this generation of LS400 is a free-wheeling design, and my instinct is to leave the cams lined up, pull the crank pulley and when it's time to install the new belt, rotate the crank to align with the timing marks on the oil pump, while using the harmonic balancer to reference my work. Does this sound doable or do I also need to find TDC on the #1 cylinder?
