Yes u need to pull it the first time, once you know what your dealing with I would say it's up to you. That first time your going to want it out of your way tho.
If your good you won't lose much coolant
Dayum! Good work Shane. It really doesn't look very hard, just time consuming. It really won't remove without removing the hpfp? Maybe uu should add the steps you used to clean the valves, and pictures of your valves?
Damn!! Nice Find... I like DIY'ing, but this one for some reason kind of scares me like others have said tho looks more just time consuming than anything.

Awesome!
Is it common to see injectors come out with the manifold? Im planning on doing this in the future but I think the injectors scare me the most.. They seem like a fragile thing to handle and reseal..
Also what tools/scrape/whatever do you use for removing the carbon?

I do not remove the hpfp, I did the first time and since then have not, I use a 16" flathead with a thin head to scrape the valves.
The injectors may or may not come out in the manifold, and the plastic cages that hold them in don't necessarily need to be replaced, either do the o rings. The manifold gasket is of the reusable type, and make sure u have a magnet to get those manifold bolts and nuts out because they like to fall into this black hole down by the oil filter housing.
