First thing I noticed: Fuel trims were -25, smell of gasoline, and a lot of white smoke from the tailpipe at idle, in addition to 192 misfires (I think the max my Aeroforce reads) and a rough idle sound/feel.

I drove it... thought maybe I could power it through it. I was wrong.

Now I see that there is a lot of oil coming out from the front exhaust manifold, I'm not sure what the rear looks like. I've also got a CEL that flashes when I accelerate by my Aeroforce won't read any codes. Since I drive for work (150 miles a day) I'm going to rebuild it but I'm not sure how far I have to go, I'm thinking head gasket and new heads (ported) since I'll be in there.

I'm hoping theres no bottom end damage as that is outside of my scope and I would hate to pay for that.

Any advice?

Update: So I failed to mention that when reinstalling the rails, I touched the alternator post and sparks flew so I wasn't sure if it was something electrical damaged. Turns out it was: but not the wiring. I shorted the injectors themselves into a stuck open position, and even after telling the repair shop this is probably the case, they still used 2 hours of labor diagnosing the problem. Injectors on cyl. 1 & 3 had to be replaced (so all 6) and the final cost was $775.

I learned my lesson, I will always disconnect the battery when working on the car.
