Exhaust full of soot after engine damage, how to improve?

[Gingerbread Man]

The engine blew up in my van, I believe referred to as engine over run caused by my turbo. The exhaust billowed black sooty smoke and made a nice puddle of soot on the road also. I've since had a new engine and all is fine and well.

Bar the plumes of black smoke that exit the exhaust when the turbo boosts as I accelerate. The garage said a new exhaust would fix it, but it's doing no harm, just a visual aspect and will one day disappear.

Can I hurry up this process as I need to sell the van in October and no body is going to want a van that chucks out black soot.

Now, could I get the hoover out....

Italian tune-up. Regularly.

Apart from that? New exhaust.

The problem is that the exhaust boxes are full of soot and oil and crap. When the pressures and temperatures get high in there, some is blown and/or burnt out. Not a lot you can do to accelerate that, really. Even taking the exhaust off, standing it on end, and banging it repeatedly isn't going to free it all.

You could take it off and soak it in something, then jetwash down the inside, but not sure if you're going to do more harm than good, and for the time and effort it'd be cheaper to get one off a scrapper

I stamp on the accelerator when no body is behind. If no other options, I'll continue in my ways :-)

When you say a 'new engine', I take it you mean brand spanking new including the injectors/fuel pump/turbo etc ?

Generally speaking, the smoke should clear within 50 miles or so. If it doesn't there are other issues...

Hmm, that doesn't sound right.
Getting an exhaust full of oil will make white/grey smoke until it has all burnt off, but black smoke would point to overfueling, a badly set up turbo or a boost leak etc.

The engine was a 54K engine removed from a car. So not 100% rebuilt as such. The turbo was a reconditioned one. The car drivers perfectly bar the smoke.

I can see the logic of the exhaust being full of soot as it did black out the road when it went and coated the tarmac, so a lot of soot was produced. If it's still clogging the exhaust I can see it being likely.

But you say it should clear pretty quickly? The garage said it would clear but after a while.

Currently there is a slight whistle from a air leak on the EGR valve which is being sorted next week.

Hopefully might all sort itself out next week then. I know nothing mechanically of cars!
