Er, thought I'd blown the engine just there but..

[j-j]

Just had a heart-stopper there. I floored it in the diesel and held a steady throttle to pass a cluster of slow hazardous drivers and all was well until the engine hit what on a carburetor you might call a 'flat spot' accompanied by a massive cloud of soot out the exhaust. It didn't blow up or stop and seemed to 'clear' but it was a "..FAAAAAAAAAK..!!!" moment.

 

So what the hell just happened? What bit of my old 1.9 XUD turdblow Diseasel just broke a bit?

 

Oddly, it hasn't recurred. It had shown a bit of a flat spot like this before that only has ever shown up on the first rush of a journey and then the engine performs as it should thereafter.

 

Any clues? Turbo dumping oil into the exhaust or manifold? I don't know diesel problems as well as petrol/ LPG problems

Cleaning its sinuses!

[j-j]

Haha, made me near clean my pants.

 

It's still running and sounds OK (for a deezell) so hoping it's alive

It's a burp. Could be anything involving an incorrect combination of air and fuel.... leaky pipe to the turbo, air in the fuel filter. Perhaps a bit of digestive biscuit getting stuck in the injector.

Mine does it when cold, there's a point where it's warmed up enough to give it full welly. Trying before then feels like a massive flat spot, then all of a sudden it just goes like stink accompanied by lots of smoke.

Sounds farked, sell it quick and buy mine

Are you sure you didn't just hit the rev limiter (were you revving the balls of it?)
