Sad How do I realign my camshafts and crankshaft.

Hello! I'm currently working on the 3.5L V6 in my 2008 Dodge Charger. I'm trying to install a new timing belt since the the bearing in the tension pulley literally exploded. I'm having issues trying to get the timing marks on the camshafts to line up with the marks on the engine housing. my passenger side cam is lined up but my driver side cam is about 45 degrees away from the mark and I'm wondering if rotating the cams and crank individually to line them up with the marks is a bad idea. If so, what are some things I can do to get them to align properly without causing any damage to my engine. Any help would be greatly appreciated and I hope you all have a great day!

Interference engine. Timing belt trashed. Most likely bent valves. Good luck!

A couple weeks ago I helped a friend with a shredded timing belt.
I set the crankshaft on the TDC mark.
I was able to turn the cam shafts to the correct spot.
(At this point it doesn't matter which way you turn them)

Then we put on a USED timing belt and a breaker bar to turn
the crankshaft over. Probably turned it about six revolutions before firing it up.

It fired up and sounded just fine. Then we put on the new belt and water pump.
(The idea behind the used belt was that if the engine was toast, I wasn't going to take it back off)

He says that he was doing 30 or less and just idling along when it broke. That may be what saved him. Pretty damn lucky!

It's an interference engine so, if the valves are bent, the damage is already done and you can't make it any worse by moving the camshafts into position.
45 degrees isn't very much, I would think you could rotate it to the correct position and install the new belt (unless you have a used one laying around).

With the belt and tensioner in place, check your marks, then rotate the crankshaft twice.
The belt keeps the pistons and the valves in synch so, nothing should be hitting anything.
After two revolutions check your timing marks again. Rotate it a couple more times just for good measure.
Nothing binding up? Camshaft and crankshaft marks all lined up? Try firing it up and see what it sounds like.
Don't worry about putting it all back together. See what it sounds like first. If it doesn't run right, then
you're probably looking at rebuilding the heads.
