2001 LS430 timing belt change

I replaced my '01 LS430 and '04 Lx470 Timing belts and everything else that was recommended (and more) myself. Overall, it was pretty easy. Just a lot of steps, but no single step taht was extremely difficult.
As most mentioned, I was really suprised at the condition of the parts I was replacing. They really looked like they only had 20-30k miles on them (btw, I replaced my belts at 100k on both cars). Lexus is really overbuilt! in a good way of course.
Stuff I did:
-Timing belt, water pump, timing belt tensioner, idler pulleys, thermostat, spark plugs, coolant, and a few more things I can't recall.
I did have to get a special tool for the crankshaft pulley. This was very critical in making the timing belt DIY a success. Luckily the same tool worked on both vehicles.
Good luck!~

When you turn the crank to 50 degrees ATDC the belt is still on. Therefore the cams rotate and are also at 50 degrees ATDC. But, more importantly, you align according to the marks on the crank and cams (the belt markings assist with this aspect) so that everything is in alignment despite the 50 degree offset.

Thanks for the reply. The left side cam is spring loaded and will move approx. 1/4 turn once the belt comes off. Prior to installing the new belt can I turn the left cam clockwise back to it's correct marks or does that screw everything up because it was moved and the other cam and crankshaft were not moved? That being said, can both cams and the crankshaft be moved independantly of each other (no belt on) as long as they are moved clockwise and end up on their timing marks?
Thanks
