I see your guys point for doing it the "right" orthodox way. But, the thing is, this is my daily driver and if Sea Foam was indeed extreemly safe, at least for the induction system, then what the heck? I've scoured the Internet and can't find one bad report on Sea Foam and it's been around for years. Surely there must be at least ONE bad report out there if there was even the minutest danger.
I got a reply from Sea Foam Sales and they said it would be fine (after fixing the oil problem). They don't seem to be paranoid about giving out advice that doesn't strictly follow the directions on the can.

Remember, the intake manifold, even if you fix your PCV oil consumption problem will probably NEVER get clean unless you took the manifold off the engine and physically cleaned it. Even after cleaning, other contamination is going to happen as the engine consumes air through the throttle body, and with the valve timing needed for today's engines, unused fuel/air and exhaust get into the engine induction system and contaminate.
That is why you need to clean the throttle body assembly, blades, seating areas for the blades, etc. They get contaminated with the dirty air coming into the engine through them, as well as the contamination that comes from the intake runner and valve called "Backwash".
Backwash is caused by engine camshaft overlap/timing that throws a small amount of both fuel and air mixture back into the manifold as the intake valve is closing with the piston beginning to come up in the cylinder, and the same scenario as the intake valve just begins to open while there is still some exhaust pressure in the cylinder.
Fix your PCV oil consumption, there are aftermarket PCV fixes that help restrict the oil's ability to get to that valve, and there may be one designed for or can be modified to fit your engine. You'll have to talk to a really savvy parts guy or someone in the speed equipment business to start with. Aftermarket manufacturers who offer solutions include Mr. Gasket Company and Moroso Performance.Maybe check with Chryslers old "Direct Connection" outlets now called Mopar Performance, through some speed outlets or your dealer.
It is not going to hurt anything to do 200 top end cleanings to your engine using SEA FOAM, as long as it is done properly. Sea Foam is OIL, and it looks like you understand the benefits of "a heat soak period".
Be really choosey as to where you put Sea Foam into the intake, you want the intake and the engine AS WARM AS POSSIBLE to help Sea Foam spread into the contamination and work at cleaning it. Look for any size vacuum port as close to the blades of the throttle body as possible, and be sure that from that location product will distribute to all cylinders equally, otherwise don't even bother, you got to get them all!
As for other brands of cleaners, for safety sake, protect all the components by using only 100%OIL based products, I believe your 44K is very heavily CHEMICAL!!
