HELP MAJOR PROBLEM :-/

[gazdkw]

I have broken down and it doesn't look too good.

I was accelerating and I heard what sounded like a stone under my car, then lost power. I drove for about half a mile then engine light came on. At this point it starting accelerating by itself. When I put it into neutral it just revved so I out it back into second and was able to crawl a little. At this point there was major smoke kicking out the back, so much that I couldn't see out the review mirror...



I stopped let it settle and it wouldn't restart. It eventually started and I crawled another 2 miles or so with no power/smoke/high pitched noise/random acceleration and then It said STOP LOW ENGINE PRESSURE.

Iv just had the car remapped so there was probably more pressure on parts.

Early thoughts are

turbo?
Balance shaft (although it didn't show oil pressure warning straight away)
Maybe a burst hose?

Please help!
