Hi all:

In the "complex" unflooding procedure,
it is always mentioned to put some ATF in the plug holes.

My question is:

Why not just use plain motor oil for the same purpose ?
After all, that's what the OMP injects.

Has ATF advantages over regular motor oil in the unflooding procedure ?

Just wondering,

Widely held speculation is this:
The ATF has detergents which can break down and remove carbon buildup within the housing and on the rotors themselves. Say you had a buildup of carbon which resulted in an apex seal remaining in the depressed position, the ATF might be able to free it up.

Assume your engine is flooded due to rotor washdown (from the excess gas) and that all is needed is to reseal the apex seals (carbon buildup not an issue here)

Why use ATF instead of plain motor oil ?

Still wondering,

because atf burns very good and oil does not. If your car is flooded just go into your engine bay and pull the egi fuse (the injectors one) and crank the key for about 20 seconds will holding the gas pedal down. Put the fuse back in and the car will start up.

Just thought I'd share...

F-Type (Ford) ATF has strongest cleaning capability of all ATF. Most people clean their transmission with F-Type ATF.

Dexron III, is the second strongest. The other stuff has the weakest cleaning power.

Perhaps F-Type ATF will clean better?

Well, then I suppose, if you read between the lines, that YES, you could use motor oil.

I don't think the original poster thought he had to say it, but if you want it spelled out, there you go.
