Can bad phasers sound like its coming from underneath the truck?? And will I lose power from it or throw any misfire codes?

 

I've heard that it will throw all kinds of codes when the phasers mess up...

 

I have an 07supcrew, phasers not an issue on this year?

 

Yes it sounds like the crank is about to come out the bottom of the pan, yes you will loose power, yes it will most likely throw a bank camshaft cel and/or a misfire cel.
Like I tell everyone, get a hold on a good scanner and watch The cam phasers adv or retard, if you see one not adjusting then boom there ya go.
Keep me posted.
