4.7L fuel rail removal

I'm trying to get my fuel rail off because I need to change my intake manifold. I've got the 4 bolts removed and all the electrical connections removed. I've read, I just need to rock the rail back and forth and the injectors will pull right out. I've tried that, but the damn injectors are stuck. I've rocked and put all my strength into it, and they won't come out. I've even tried to pry up on each injector, but they're still stuck.

I'm getting pissed at it, and my neighbors are hearing me cuss at my Jeep, so any pointers in how to get that f'n rail removed would be appreciated.

Re: 4.7L fuel rail removal

The seals on the injectors can get quite dry over time and keep the injectors from moving. Try some penetrating oil like WD40 to get it moving. There is nothing else holding the injectors in the head.

So, I've got everything removed, except a couple injectors are still stuck. I'll get them out, but I have a question about cleaning out the carbon/oil build up in the ports.

I'm wanting to get most of that crap out before putting on a new manifold. Would wiping it out, then using carb cleaner work? I could probably stick a shop vac in the other port to keep as much shit from getting any farther in. Thinking this would work? Or should I just leave it alone cause I could mess more up?

Re: 4.7L fuel rail removal

I would take a lot of care not to get any loose dirt, which could enter the combustion chamber or get stuck between the valve and its seat. I would prefer to run some carb cleaner or seafoam afterwards, to clean it out.
