So, I'm in the process of replacing my timing belt because it failed and it's all ripped, but before I removed it, I'm trying to set the timing, so crank shaft is set the to right is set at 1 on the line but the one closest to the fire wall is offset its ahead of the mark. All match except this one. So how can I get them all set to the mark? Or at least this one because the other two are already set. But everything I turn the engine to reset the marks it always ends up ahead. I'll post some photos hopefully it's clear enough but if not I'm sure you know what I'm getting at. Always am I also able to pull the belt off then set the timing before I place the new one on. I'm just a back home mechanic so still learning. Please need help. Greatly appreciate it.
By the way the belt is still on but pretty much rip to shreds.

Hello,

Look below for the timing belt replacement procedures. The diagrams show all the markings and procedures. I think it will be easier to follow.

This Odyssey could be equipped with a J35A6 or J35A7 engine, both are 3.5L (depending on where it was manufactured). I have included instructions for both of the engines.

Thank you for thus info, I followed all instructions I got all marks online placed the new belt, turned the engine about 7 to 8 full rotations clockwise and marks still lined up. Put everything back cranked up the car and car won't give. My obd shows all 6 cylinders misfiring. It cranks but won't turn over. As I press down on the gas pedal it finally cranked over but sputters and backfires and shuts off. And the motor just sounds really bad. I think I got some bent valves. Any suggestions at this point?

Was the timing off before you took off the belt? If the belt gotten starched enough it can damage the valves. But it will have to be really loose or broken all together.
As for checking for bent valve, you will have to remove the cylinder head to find that out.
If you like just open another thread for the cylinder head and I will provide you with the instructions for that.

Will do thank you, yes when taking off the timing cover, I notice the front sprocket was off by almost 2 to 3 inches. Everything else was lined up correctly. Belt was ripped in shreds. But still holding on.

It's tough call. But if the sprocket was off by that much, there is a chance of valve damage.
