I was driving to work the other morning and got to a spot where there are 2 stoplights that are very difficult to catch both green. The 2nd light turned and then my light turned, it is an entrance ramp to a highway, so I hit it pretty hard trying to make it. In 2nd grear, at full boost, high revs, about to hit third, I get a boost cut. Engine light on, high emissions code, no boost, lots of oily smelling exhaust. I limped it back home and pulled the codes tonight. B2AAA, P0100, P0302, P1113B. What did I break? I thought I blew a boost hose or something but they all seem intact. I have spark plugs coming. The misfire code concerns me a little. Has anybody else had the same issue before? Could I have damaged the BOV or diverter or whatever it is called on these things? Thanks in advance!
Not looking good so far. #2 is full of oil, the plug was completely dry and clean. The other 3 plugs are carboned up, cylinders were dry. I'll post some pics when I figure out how. Running to town to get and adapter for my compression kit so I can run the numbers.

Yeah, you next step is compression to make sure. If compression is good across the cyls, then that was gas in the cyl not oil. In that case, your coil might've given up. You could swap coils to see if the fault moves
Swapped the coils and cleaned the plugs. Codes all went away in the shed, but it is still running bad and smoking like a 2 cycle. New plugs come in the mail Monday, I'll get some used coils Monday too. See if it all goes away.
New plugs and "new" 70,000 mile coils installed. Got a new code. Rich on bank 1 and she backfires a little. Do I need new O2 sensors too? Car has 109,000 and it was blowing oil for the last week.
Assuming it is - there's the two most common N14 issues, 1) carbon build up, 2) PCV system gone bad causing oil high oil consumption and even more carbon build up.
This particular car had the head off at some point after a timing chain failure, all done by a Mini Dealer. I would assume they took care of the carbon buildup while it was apart. As for the PCV system, I'll look into cleaning that our or replacing it. For now, i think i'm just going to go run this this hard and see if i can burn out the cat. I think it is a little full due to the misfire and running rich for a miles.

Doubtful they cleaned the valves or the PCV when it was in for the timing chain.
I found one potential leak point. On my intake manifold, there are vacuum points on each rubber. The plastic tee fittings are all brittle. Where can
I find replacement parts? The local discount Auto parts places don't carry fittings individually.
Just an update... I stopped by my local Mini Dealer (3hrs away) and picked up the vacuum tee fitting for the cold weather intake. I then dove into the pressure side of the boost circuit. I found the diverter valve to have failed. A replacement is on the way, along with new intake manifold seals, a new valve cover seal and the vacuum pump rebuild seals while I'm in there. I will probably blast the valves too since it is all opened up. I'll report back if these all solve my issues. FWIW, the throttle body was super clean due to the cold weather intake. All that PCV oil mist goes directly onto the valves!
