So I replace my Ign wires the other day and noticed I few breather hoses and air hoses that were bad so I replaced them today now the car is running like **** and blowing oil smoke

I would start by making sure the ignition wires are on correctly and making good contact with the terminals.

there was a hose connector that was broke on the front left side of the motor and I think that is the problem!!!

wires are fine checked them and drove it for days before this problem came up

What specifically did u change and what brakd parts did u use? Reason I ask, I did a complete intake job on my sec and chased a drivability problem for a month becuase of a substandard air hose (URO part).
