'Motor Vac' a rotary? Good or bad?

So I put waaaaaaaaay too much ATF into the top of this engine we're working on. And while we've gotten most of it out, we're pretty sure that there's still some up in the intake manifolds. Now, we aren't looking forward to ripping them apart after we just put them together.

A neighbour suggested getting a Moto Vac or Motor Vac. Take the car to a shop and they vacuum the **** out of the top of the engine, or something like that.

I don't like the sound of this, yet the idea of sucking the ATF out rather than a disassembly is kind of appealing for obvious reasons.

Comments? Or suggestions on alternative ways of getting the ATF out of there? It keeps fouling the plugs each time we go for start-up, so 'burn it off' won't be such a great suggestion.

Motor Vac

The Motor Vac process DOES NOT vacuum the motor(Engine). The Motor Vac is a Fuel system cleaner/diagnostic tool. It (Motor Vac) interupts the fuel feed to the engine (becomes the new fuel pump/tank) which has heavy? (effective, IMO) cleaners.

It is used to clean the fuel rails and injector baskets and pintles of any deposits. I have try this with mild return. Also part of the motor vac process is to spray with a long straw throttle body cleaner into the intake track to clean carbon/gum bluid up.

So, once again, my neighbour doesn't know wtf he's talking about.

You should have heard the fairy stories coming out of his head when he saw that I had a 7. :tard:

Thank you!

Dude, ther eis not really such a thing as too much atf. You cannot flood a rotary with atf, and you cannot hydrlock a rotary with anything. All that will happen is you keep pouring it in is that it will get pushed right back out the exhaust port, which is near the bottom of the engine. TH most it will hold(before pushing out the rest) is about 1 cup per chamber. Just crank it over a few times and all the excess will get thrown out the exhaust, wher eit will smoke its way out upon startup.

No way in hell Id worry about or try to get atf out of the engine. This situation will handle itself.
