Nothing more than a split intercooler hose.
possibility i suppose................
|
|
Let us know ! This could be a reference thread !
|
maybe it does sound like compressed air being force out, then again you mind can play tricks on you, cos that would probably be cheaper to fix!
where is this pipe, under the ally heat shield on the exhaust side of the turbo?
|
the noise/hestitation/hiccup is load+throttle related, revving the engine up at standstill gives no noise or smoke, driving steady isnt a problem
its coming under load (hill) or harsh acceleration where the problem comes in, once 2500 rpm is hit, which means to me it must be turbo-related.
|
cursory examination has revealed nothing, i squeezed a few rubber sections joining metal pipes (2" dia) - one had bands of wires round it, is that boost or aircon, damned if i know
theres no oil mist anywhere, no drips, no leaks
revved up at standstill looks/sounds perfect...
crank pulley feels ok too....

As you look at the engine the pipe is situated between the engine and intercooler. The intercooler is a secondary radiator that cools the air and is located behind the water radiator. In appearance the intercooler hose looks the same as a water hose and is easy to get the two mixed up by just looking at them. It runs from the top left hand side of the engine to the bottom left side of the intercooler. Look for a damp spot on your hose and surround and also watch for a fine mist. The intercooler is a high pressure system and if you pipe is split the turbo will not function at full boost. The split will open and close very quickly and it is this that gives the impression of an engine missfire or hesitation.

Looks like a trip to Ford between hospital trips

I still say this is nothing more than a split hose. It took me the best part of a week to find it, and it was right there under my nose. Keep looking there are more flexi pipe around the back and under the engine.
|
my under car days are over, ill have to ring the sick bay....
|
looks like its a split hose, found the tell tale residue right under the EGR, on a bend in the 2" pipe running straight down
ford say it should be p/n 1122510 bout £20 plus vat, can i go to look at his screen....but no stock
wheres my gaffer tape...................
|
|
6 feet of duct tape and 4 cable ties sorted it till ford get me one
|
glad I was able to help.

glad I was able to help. Paul
thanks a lot, cheaper than a new turbo, thats for sure!
after a run and some STP injector cleaner (and a quick clean of the EGR valve) its back to its old rip-snorting ways, when i locate the fuel filter ill give it a service, i found the oil filter while i was underneath the sump....
|
part number PF 1222831 £25.10 plus vat
at least dick turpin had the decency to wear a mask
|
seems besides the regular problem of this hose splitting, the EGR valve and MAF sensor can both cause problems, i have pulled of and plugged the vacuum pipe tp the EGR (which i have cleaned out and the car is running almost smoke free, and certainly without the big plume of black smoke it had before
i shall also be cleaning the MAF sensor
|
i shall also be cleaning the MAF sensor
Best way to ruin it.
|
only with some contact cleaner from maplins, not a wire brush
|
Contact cleaner will finish it; it must be a totally residue-free solvent and preferably don't clean it at all - if it ain't broke etc....
|
|
shall investigate the state of the intake manifold then, which seems to be another culprit, with large build ups of gunge just like the EGR gets.

Hi All,
I have a very similar problem on my focus tdci 04 115. Under load it sounds like the exaust is blowing with a whiring sound, that and the engine is a bit rattley? When I depress the clutch the rattling stops.
I will check the turbo pipes the weekend but any advice would be gratefully recieved.
|
If there's soot on the underside of the engine cover it's a sure sign of a split pipe.
|
I have the same noise problem, rattle goes away when clutch depressed, if clutch pedal pressed slowly it tries to push jerkily back. this is on a Mondeo 130 tdci 52 reg,
141k . I thought the turbo had gone but traced it to a split hose. Noise still there though. I thought maybe the thrust bearing or clutch as they are origional items.
|
|
thanks for the very usefull information . had the same symptoms on my 54 tdci 130 mondeo. missfiring and whooshing noise on acceleration, checked it out on this advice site . found problem straight away .Big shock when ordering new hose from ford dealer. £48.75 !!!!!! daylight robbery ..
|
|
I had the same symptoms - temporary loss of power and puffs of black smoke etc., so I took Paulontour's advice and found a split on the bend of the intercooler hose which I have sealed with super glue and loads of duct tape and everything is now fine.
Many thanks to Paul - you are the man...............
