Twin Spark - Conrod disaster : Advice?
I bought a W reg Spider 2.0TS three weeks ago from a local sole trader.
It seemed very well looked after, with an 83k mileage and FSH, and I enjoyed the first 500 miles or so.
Last night, I was travelling home on a busy dual carriageway and there was a massive bang and smoke.
I have a huge hole in the Offside of the Sump, so it looks like a conrod has tried to make its escape.
For a brief few seconds before the bang, the revs started rising, which was odd.
Obviously, my first call is to the retailer as the car had a one month warranty.
However, I would appreciate advice:
1) How much is the going rate for a recon/secondhand Twin Spark engine?
2) What could have caused the increased revs before the bang? I'm wondering if the piston rings went and let oil into the combustion chamber, creating that effect I've heard of on diesels when they run uncontrollably on their own oil? Or if it was something external, such as the ECU or throttle potentiometer? I'd like to establish this, as I don't want the same thing happening on a replacement engine.
There was no warning. Temperatures were fine, and the oil level was OK. Judging by the amount of oil that is now on the road, it wasn't a starvation issue...
I'd appreciate any advice and guidance.
