plz.help Rx7 wont run[detailed]
so my brother stalled it off of a cold start, once he tried to start again its wouldnt run. So i came t the conclusion that the spark plugs might be fowled, so i went to the cities and got new plugs. I installed them, and still it bellows smoke, and even seemed to spit a little bit of oil from under the upper air intake. Not knowing what could be possibly wrong i have searched through forums of similar situations and found nothing that is really the same. i have checked compression which turned out to be fine(whew). checked plug wires and all of them seemed fine, but one looked kind of iffy(the T2 wire) which shouldnt make much of a difference on the idle, because they dont spark until 3800 rpms? am i right?
i have also tried multiple unflooding procedures several times. nothing has seemed to work.
i came to the conclusion that it could possible be a coolant seal. once i researched about coolant seals, i learned that there is a white smoke that will bellow and smell sort of sweet, But the smoke seems to be more blueish. Would anybody be able to point me in the right direction, because i am lost.

The trailing plugs fire at all rpms, as do the leading plugs. How did the rear trailing plug wire look iffy?
Are you *sure* your brother just stalled it? he wasnt driving the car, or messing around under the hood? How long have you let the car idle for?

Blue smoke is oil, btw.
It's a shot in the dark, but make sure your MAP sensor is plugged in.
the map sensor is the white sensor on the back of the firewall? if so i have checked it.
And ya im sure he only stalled it, cuz i watched him do it. The car doesnt really idle, but barely on gas i let it idle for like 5 mins, seeing if it would unflood itself.
i dont really know what else to look for? but i did find a vacum line off, the one with a black plastic thing on it.

the map sensor is black, not white. it's located on the rear driver's corner of the engine bay, along the back wall (opposite the steering wheel).
if you found a vacuum line off with the small black check-valve inline, then that's most likely your problem.
