I was wondering if it would be easier to use engine vacuum to draw in the ATF/Seafoam/MarvelMystery fluid into the engine?

Cranking speed of 250-300rpm seems to create enough vacuum to pull fluid straight from the bottle using an extended vacuum hose. Both rotors pull own fluid and coat entrails evenly and everywhere.

Anyone know which vacuum hose feeds both rotors somewhat evenly? What is the big vacuum hose(pcv?) connected to the top of the dynamic chamber intake (drivers side U shaped hose)? Using a funnel, I can conservatively pour fluid into it while someone else cranks the engine over(fuel pump & coils disconnected). Anyone ever try this?

I have thought up of a couple of cons:
dead battery, starter toast, hydraulic lock

But, if your careful, this seems to be an easier more thorough way.

CAN THIS WORK?

I did the atf trick using vaccume last thursday.

I made some pics on my site

I was looking at it though and i forgot to mention that the hose I used had a 1/8 diamater, but if you take the BAC hose off that i showed in the pictures and take that into the hardware store you'll be fine.

(my service provider ususally shuts down on fridays for an hour but the link is working right now.)

You could also just let the engine suck water up through a vacuum hose instead of ATF. Works great, just don't do it for more than 30 seconds or so. I did it for 3-5 minutes (1 Liter of water) and my exhaust got so hot it started to glow.

Thanks for the link. The picture that showed where to connect the hose and bottle was great.

I had a friend turn the engine over(several 30 second cranks) with the fuel pump unplugged and crank position sensor unplugged. I did this on a cold engine to prevent any of the Marvel mystery oil from evaporating. I want to remove carbon not create it.
The engine sucked up half a quart of Marvel Mystery oil. I can only imagine how much smoke will be created tomorrow.
Enough air is being sucked in at the same time that there is no worry of hydraulic lock. Hopefully, the inside of the engine is washed.

I plan on pulling the catalytic out to allow some of the fluid to drain out of the exhaust manifold.
I might even run some FI cleaner to wash out the Marvel Mystery stuff tomorrow.
Now I have to wait 24 hours and maybe another 24 after the FI cleaner.

STEAM is an excellent way to rid the engine of carbon. Heated water regulated/injected through the vacuum lines should help blast all the carbon deposit away. I would have done this but my car was running very poorly.
