| 313 cdi nightmare, blown engine
Hello,
I am deep in despair. I have a yr 2000 313 cdi with 200,000m or so. About 6 months ago we discovered a VERY severe case of injector blow by. Approx 3 garages and £2000 later we thought it was fixed when suddenly the engine started making a loud whistling noise then stopped working.
We replaced the engine with a re-con unit. It was still whistling and burning lots of oil then the turbo expired. We replaced the turbo.
I finished the job this afternoon and started the engine. It was idling fine, warming up nicely for two minutes or so when I noticed a fair bit of smoke from the exhaust. There was a lot of oil through the induction system and intercooler presumably from the turbo failure and I assumed this residual oil was causing the smoke.
I increased the revs a little to say, 2000 to try and blow the oil through a bit and see if the smoke got any better when the engine suddenly revved out of control right up to say 4500 rpm or more (revving it's nuts off) without me being on the throttle at all. I turned the key off and removed it but the engine kept revving really hard and I was frantic trying to think how I could turn it off. Before I could do anything the engine stopped abruptly. This was because it had blown no. 2 injector a good three inches up out of the head, snapping the hold down bolt and spearing into the induction manifold........I did and still do feel sick. I think I'll be able to laugh about it in a few years time as it was very spectacular.
I don't know what to do and need to have a think but does anyone have a clue what would make the engine go crazy like that? I've never seen anything like it ever. And also surely it should be able to rev as hard as possible without blowing an injector out of the head? |
