Exhaust giving out lots of smoke?

[hussnainh8]

You've obviously broken something - Not sure what you are expecting when running flat out - things get hot and go bang.

Whether it is the turbo, or something engine internal related remains to be seen, further investigation i.e. stripping down will be needed to resolve.

I'd be pulling the downpipe and checking the hotside of the turbo for play and evidence of oil leakage, I'd be dropping a boost pipe and checking if it is full of oil to see if originating from the cold side, I'd pull the intake and check for evidence of oil originating from the PCV feed in to the turbo housing, along with the PCV on the front of the engine going in to the inlet manifold to understand where the oil is originating from. Don't fit a silly PCV delete - if the current one is working correctly (5 seconds to check) then leave it be

I will check all that later.. how can I check if my PCV is still working? There are no codes for it on VAGCOM but maybe it is faulty?

Factory ED30 is limited to 155mph, and only runs 0.9 bar boost.

Your car is very different.  Double that boost and derestricted.  The turbo gets mega hot when nailing it round to those speeds because of gearing and wind resistances.  99% of people rarely exceed 100mph in this country, too many people, too many sh*t drivers, too dangerous.  160-170 is uncharted territory for these cars and UK tuners.  Max speed they see is flat out in 4th on the dyno, so 120ish.  In other words, although you may not understand it, it is possible to cause damage to a tuned engine running it flat out for an extended period.

It was literally 3 seconds.. I saw the speed at 160 and revs at 6000 and thought this is too much and let go of the accelerator.. its still running perfectly fine other than the silly smoke I do not seem to understand. Lets hope I have not broken it. Just paid £6500 for the car :(

It's probably the turbo then if the engine is still running smoothly and pulls well, but you'll need to get it checked out as per Dan's suggestions.  Turbos are easy to come by, so not the end of the world.  If it was rebuilt 8K ago, perhaps there's some recourse with the reconditioner.  Any paperwork with the car for the rebuild work?

The turbo was also replaced the same time as the engine was done so I am very suprised that the turbo could be faulty but I guess im going to have to spend some money and get it all checked out.

Remove the oil cap with the engine running.  If the diaphragm has popped, it will create way too much vaccum under the cam cover making it very hard to remove the oil cap.  This can actually cause your white smoke issue in extreme cases. You should only feel a slight bit of vacuum when removing the cap.

Might be worth replacing it anyway as it's not an expensive or difficult part to replace.

Yes today I tried taking the oil cap off to see if the engine would judder and it was definately really hard to get the cap off the engine while it was running .. was twisting it a lot thinking why is it on so tight but eventually got it off and as soon as I got it off the engine started juddering a lot as if it wanted to turn off. I also took the pcv pipe off to see if any change would happen and the engine started juddering again... does this mean I need a new diaphagram (whatever that is) or a new pcv valve or is it all okay??

I only wanted to show matey what a machine it was and he had a black GT and was doing 120mph.. I had to get passed him so had to do more. Never again.

There's no 'had to'. I hope this has taught you a very serious lesson. Immaturity and Sheer Muppet Zone doing 160 on a UK road - unbelievably irresponsible. You are very lucky not to have killed yourself, or worse some innocent family out on the road. If you haven't totally sha**ed your engine already, I suspect it won't be very long before you do manage to completely knacker it - and no blaming anyone else. IMO......

Excuse me? Who even asked you for a lecture? If you cant help with the question then fuc* off. I didnt ask you to give advice on speeding.

Right, a warning.

I'll tell you the same.

Do not post up on here that you've been doing 160mph on UK public roads.

Do not verbally abuse a forum member for speaking sense in the face of idiocy.

Do try to be grateful for the advice you've received from several forum members in a short space of time.

Locked.
