1993 Bronco engine wont idle
 

I have a 1993 bronco, that the engine will not idle on. When I give it gas. it backfires and has no power. Funky smelling smoke comes out of breather and the dip stick, when you put a rag over them there is oil on the rag. we did a engine flush, it helped but did not fix the problem 100% still acting really rough any ideas?
Thank you,

Clean or replace the PCV (valve) for starters, if that doesn't solve the problem at least partially then I've got bad news for you... a ring has probably failed, you should also inspect the spark-plugs to see if there is any oil there (which I suspect from the misfires you report).
