So I was test fitting some s2k injectors to check for leaks and my friend decided to crank the engine instead of turning it to the "on" position.

Long story short, There was a puff of dust that came out of the engine, it sounded like "POOF" and there is maybe about a cup of oil that leaked out. Anyone know what could have happened?

 

Did you turn it off immediately?
A cup of oil missing for a few seconds will probably not hurt anything. Just make sure to fill it back up asap

 

yeah, it was shut off instantly. I just don't know if I blew any gaskets or where the oil came from.

 

what area did it leak from?

 

s2K injectors? niiiicee , but wtf that caused you to leak oil?

 

maybe it shot out through the valve covers if they werent tightened completely

 

No clue where it came from, it was just dripping onto the floor from under the car. AP2 S2k injectors don't fit, don't bother trying to make them fit... go with the RDX, it's the same amount of modifications + a whole lot cheaper. I'm going to go with RC 440 or 550s, and just save myself the headache.
