Have not done this to my 4runner yet, though.

Best point of entry is the brake-booster vacuum line. I just disconnect it from the booster, turn it upward and use a small funnel to guide the SEAFOAM in without a mess.
Don't pour it in too quickly or you can cause hydrolock........engine disaster.
It is hard to stall the engine, but if you can, do let it sit for an hour or so and then come back out for the show.
I suggest changing oil pretty soon afterwards. You don't want to chance running with diluted oil.
