OK before you watch this video, the car has been just on a 20 miles trip so it was at idle temp, heres a

Turbos seals gone or worse? I had the exhausts done, was on the way home and i just had a huge amount of smoke trail, it looked like i was on the dirt road, at traffic lights i couldn't see the car behind or anything.

 

Can someone please suggest what it is?

 

Thanks for looking

 

*Edit: Smoke is extremely bad out of the left one, and a tiny bit on the right one

Sounds to me like rear turbo seals then. :( But get Paul to check it.

Yep was a turbo seal, if i dont use the turbo no problem, if i use a turbo then tons of white smoke

So you coming to sundays meet then? without using turbos:x:

To be honest if the seals are gone / going on the turbo's, it's not long before the spindle will start to come loose. When it comes loose, the blades will start making contact with the inner housing walls. Little metal shards then get pushed around your engine, they eventually get into your cylinders. Most of them will be melted down but some of the bigger pieces may find a lovely home between your piston rings, where they will have lots of fun scratching up your cylinder walls. you will then start to drop on compression on the effective cylinders.

 

Before you know it you'll not only need to replace the turbo's but you will also be looking at either a new block or a bore and fitting bigger forged pistons.

 

So my advice would be don't drive it.

 

Ps.

Forgot to add, above I just told you what happened to my car back at Billing 04.

Dam... Im sorry bud. Sounds like bad news. Hope you get it all sorted soon!

hope this helps:)

Have you thought about refitting the old exhaust for the time being? You've obviously changed the back pressure which is why the seals are weeping. Refitting the original exhaust will/should change the back pressure to stock and therefore should stop the seals weeping. The turbos will need replacing/reconditioning at some point, what you've done is uncovered a problem that was always there. Refitting the exhaust should stop it being noticable.

His old exhaust was rusted out I think so dont think that will be an option...:(

maybe a roll call for someone who is taking of a standard exhaust for the emergency "stop murts car braking even more than it already is" campain??

No it wasn't, it was just the shields that were rusty.

Oh ok, so maybe he can then.....

Jimmer had some spare exhaust stuff knocking about. Not sure if he's still got it though.

buy a bicycle........ like me :D

Just back from pauls, did a compression test all are 130/140 so normal for the age of the engine (14 years). The white smoke is the turbo seals and it likes drinking my nice dear oil! going to phone paul tonight and hopefully and reslove the problem, maybe get the turbo seals changed or maybe an engine swap. If worse comes to worse then im sorry but i will have to sell her :(

I would of said it was defo the turbo seal, No need to sell tho just get bigger turbos :D

Engine swap? Unless you have the cash to rebuild an engine, I'd keep the current engine. Just try refitting the old exhaust. Should go away. The back pressure in the old system was stopping the old seals from weeping.

cannot afford rebuild :'(

Then why change the engine?

replacement engine is usually cheaper

His compression isn't too bad though.

very true si

Putting in a used engine is always a bit of an unknown quantity. I made the silly mistake of buying a second hand engine. Never fitted it. Used it as a benchmark to rebuild to a good stock standard. Contemplating building a high performance engine now with uprated internals, turbos, injectors, intercoolers etc.

I dont see how putting on another exhaust is going to help. The damage is done. The seals now leak oil and only new seals/ recon will fix the problem.

130/140 compression is not brilliant but isnt terminal either. There should be more mileage in the engine provided it isnt abused/thrashed.

The back pressure the original exhaust had masked the problem of weeping seals though. Refitting the exhaust will mask it again. Just a temp measure if Murt doesn't want to drive round with a smoke screen behind him.

Murt, don't change your engine, it's sounds quite acceptable. Just get some known used turbos. There are people on here that have changed their turbos for bigger models when the old ones were still running good. They will surely let them go quite reasonable.
