Help with cleaning engine components and Cylinder heads
I have a 2000 Ford Expedition 5.4L and I am doing a top end rebuild by myself due to blown head gaskets. I have 195K on the engine and I bought it fairly recently so I have no idea of past maintenance or upkeep. I am going to be replacing the head gaskets, plugs, igniters, and all the gaskets I come across. As I'm pulling things off i'm coming to realizing that the head gaskets were not the main problem. The entire throttle body is clogged up, the iac is pretty bad, and generally my engine is just terribly dirty. I've used TB cleaner and gotten the TB cleaned up pretty good and I used some TB cleaner on the iac as well.
My question is what can I use to clean the TB to factory condition, like no carbon buildup at all.
Also, how do I clean the egr? Everyone says it needs to be cleaned, but I don't know how.
I have the fuel injectors removed, is there anyway to clean them outside of the engine?
The entire Intake manifold is disgusting and I've used some brake cleaner, but it doesn't seem to be making a huge difference. What can I clean it with?
I am obviously going to have the heads machined flat, but they need to be cleaned thoroughly as well. I don't have a huge budget so I would like to clean it myself. Is this a plausible thing to do and what would I be using to clean it?
Is there a good concentrated solvent that I can dilute in a bucket and soak bolts and various smaller parts in?
I pulled my coolant crossover off and it, along with the rest of my coolant system is ridiculously dirty and almost rusty looking. Is there something I can do while the engine is dismantled or should I just do a coolant flush once its reassembled.
Is there anything else that I can/should clean while I have everything torn down? Anything that is common to break or deteriorate? I'm almost at 200k so should I be doing the 200k routine maintenance as well?
Sorry for all the questions, but i'm trying to do this right so that I don't have to do it again. Thanks everybody!

Throttle body I would clean it in gas and get some bottle brushes and run them through all orifaces. TB/carb cleaner through the EGR, IAC. Clean the head and block surfaces w/ alcohol. It dries quickly and leaves no residue.

Hi,
I have a 2000 f150 with the same 5.4l engine with 236,000 miles and I just had to replace the intake manifold because the plastic cracked and coolant was leaking into the cylinders and causing misfires. The leak was on the passenger side right in front of cylinder 1. I just bought a new Dorman intake manifold off amazon for about $150 and it solved everything. I'm not sure if you have the same problem but this might be something to look out for.
