Let us know what ya find.

 

So I'm getting 13.5 to the injectors and the signal ground to fire injector at least to cylinder 1 so and the same to the coil. Could when I was doing torque converter bolts I rolled to engine both ways getting bolts out. Could it have jumped time on driver side. It sounds pretty bad from front of engine

 

Shouldn't have.... unless the tensioners are really bad......

 

There's a bunch of racket coming from the front
But its got 153k and I know these 4.7L engines the timing chains are their down fall
If I pull the valve cover I should be able to see something, right?

 

Maybe. I would think you would at least be able to turn the crank to TDC on #1, and see whatever passes for timing marks on the cams.

 

That's why I'm pulling the valve cover so I can verify timing marks and look at chain guides

 

The problem with checking timing on 4.7s is the timing marks line up once every 32 revolutions I believe. Short of rolling the engine over up to 32 times until all the marks line up, you cant really know.

You could pull the valve cover and see what things look like, if there's lots of carnage visible it should be obvious. Its funny this issue would present itself suddenly doing a transmission changes. Rolling the engine back and forth should not cause a timing jump unless something was already happening. Short of a plastic guide failure I couldn't see them being loose enough to jump, and this you would notice prior to the transmission I would thing. The tensions have a ratchet design so they can only collapse so far with loss of oil pressure.

If you're mechanically inclined I would find it more cost effective to just pull the front cover. Or first pulling the valve cover and seeing what you can see, if there's carnage already at that point, pulling the motor seems mostly inevitable, but short of bleeding the upside down cooling system, the front cover is a relatively easy job and good chance its due for a new water pump anyway. Then you can see the guides in full view, and reset the timing and/or replace the guides/chains/tensioners.

With the valve cover of you could vice grip the cam in a non critical place and try rocking it, it should not move or just slightly if anything. There's just the pressure of the lifters against the came so its not hard to turn it over if the chains are that loose

However based on your codes a mechanical failure doesn't make much sense anyway. #8 control circuit I would test if #8 injector has signal to fire, and #7 misfire could be a companion fault due to #8 not firing. Noise rotating the engine by hand definitley is concerning though, could also do a compression test to check for dropped valve seats, that would rattle.
