Technical Intercooler Hose Split (sounds like a hoover)

re: JTD - Exhaust Smoking

Have a go yourself or get a local, absolutely avoid the dealer at all costs.

LOL definately

IF it is that lower inter cooler pipe, then its dead easy to replace if you dont mind getting a bit oily!! I recommend replacing the two metal clips that secure either end of the pipe with "real" jubilee clips.

Get someone to hold the revs over 2k whilst you have a look underneath. the pipe should become pressurised as the revs increase and you should hardly be able to squeeze it. If its split, you'll hear leaking air and the pipe wont pressurise properly.

If its fine, then there are other things you can look at before going to fiat if you so wish.

i have abolsutey no idea what i would be looking for, so i wouldnt know what to do... unless of course you can take a picture of what i should be looking for. I will prob have to take it to the garage over the weekend.

Ok ... ive done that and there does sound like there is a hissing sound coming from underneath, but how does that explain the smoke coming out the exhaust?

I got my dad to rev the car higher and smoke POURED out unbelievably excessivley and oil came out too, pictures below shows what it did to the drive way ... what can i do? and what could it be? and how much is this going to hurt my wallet?

re: JTD - Exhaust Smoking

It sounds identical to the problem I had (split hose) and the whooshing sound. As said earlier, worst case is just short of £200 but if you get the part and fit it yourself then you can save a lot.

i dont get why a split hose would make smoke come out the exhaust though? would a local garage do it for cheap do you reckon? what if i get the part and its not that?

If you are getting a hissing noise then it's a split intercooler. I nearly shut down the M6 motorway as my smoke was that bad I could have caused an accident. Not an expert by a long way but if the hose is split the turbo can't kick in so the ECU stops the EGR valve from working thus the black smoke - something like that but someone with the right technical nouse will let you know.

Any garage could do the replacement if you get hold of the part. I would have done mine easy had I not been a long way from home at the time.
 
re: JTD - Exhaust Smoking

ok ... any ideas where i can get the part from for a good price?

You mean the part you think you might just maybe need but on the other hand it may just be something else you actually need. It's seems clear that you are out of your depth, it's time to bite the bullet and take it to your local independent Fiat garage. Oh and don't forget your credit card!!
 
re: JTD - Exhaust Smoking

One more thing to check, what's the state of the air and fuel filters ?


you reckon that could be the problem? when i had it serived they only did a basic service and didnt change these on the car? and i assume they must of checked for cracks and leaks. It was only 2 months ago since the service, could of happend since then i suppose.
 
re: JTD - Exhaust Smoking

Can't see them checking for cracks myself, especially when their idea of a service is an oil change. Did this come on all of a sudden or was there a build up to it. The hose splitting will create extra smoke almost immediately. Filters & the like might give a slow build up to the problem. You can order one from a dealer for around £60. Bet your bottom dollar you can sell it here if you don't need it.

If the hissing is there then it's the hose, simple as.
 
re: JTD - Exhaust Smoking

where would the hissing come from, my dads had his head under the bonnet and there nothing there that looks broken, would the crack be noticeable? its hard to tell if it came all of a sudden, but we were revving the tits of it yesterday and the smoke wasnt that bad, but the other day it was so excessive, i mean you have seen the pics of what it did. its due to have the filters cahnged on thursday because i want the changing anyway as they havent been done before that i am aware of so if the doesnt sort it maybe somone can help me to fit this other things that it could be?

re: JTD - Exhaust Smoking

He will need his head under the car not the bonnet. Where the undertray touches the intercooler hose is the obvious place to look. Sometimes the tray rubs the hose and creates a split/hole. Do a search on intercooler hose and you can see some pics.
 
re: JTD - Exhaust Smoking

You've been given plenty of useful advice on what to look for in this thread but at some point you're going to need to get your hands dirty (very dirty). You must get under the car to properly check for a split intercooler hose (obviously you must remove the undertray).

If you don't want to do that then a get a competent garage to check it for you.

The reason a split hose produces lots of smoke if because the air which the turbo has compressed escapes from the hose (hence the hiss) but the ECU doesn't know this so it keeps squirting diesel into the engine which produces a very rich mixture with lots of unburnt fuel (which you see as smoke out the rear).

It may not be the hose but you wont be doing your engine any good running it like this :(
 
re: JTD - Exhaust Smoking

Hello to all, been a while!

Just to throw a spanner in the works i have a front mounted intercooler, and have the exact same problem hissing, nice whooshing at 2 1/2 grand and my pipe work is sound all brand new from turbo rite thru to engine! i Do how ever get the occassional black smoke if im holdin speed but nice white smoke wen i cain it!

But sum valid input is always helpful, sum say that fuel can leak into the oil sump and this results in being over oiled! i had this once AA man resued me by suckin a load out! but my engine royally died ticked over for ages jus coughin the s*** out! now i never fill my oil to the top line jus monitor it very carefully!

If you do figure out what ur prolem is dude i wud be very interested what u have found?!?!?
 
re: JTD - Exhaust Smoking

my pipes are also all ok, no cracks in them as far as me and dad can see. Checked both pipes below and cant find any cracks in them. The smoke seems to decide when it wants to be bad, its doesnt do it all the time, mostly when i floor it. However at low revs when the engine is struggling. say for instance when i go into a corner on a really steep hill to slow and the engine is strauggling to find revs, the smoke will poor out.

Im having the Fuel, and Oil filters changed on wednesday to see if the helps anything, if not its back to square one.

re: JTD - Exhaust Smoking

That picture only shows the turbo to intercooler pipe. It's the one the other side which I gather can be the problem (intercooler to manifold - it's hard plastic).

Another check to do, that's real easy, is to disconnect your MAF sensor and then see if smoke decreases and mpg goes up. If you don't know what I'm talking about then use the Search tool. Absolute doddle to do.
