smoking exhaust, sucking turbo, spitting dipstick

Hi

I have read a number of threads about smoking exhaust and lack of power and I thinbk I am pretty much screwed. However. Just to check, here is my list of woes:

Last week:
Wednesday night - main engine warning light comes on at 70MPH. stays on for 10 seconds only. I have not seen it on again.
Thursday morning - things 'not right'. Noticed a sucking/hissing sound at about time turbo cuts in - 2000RPM or so. Auto box not changing in right places. Power loss throughout range.
Thursday evening - impressive amounts of grey smoke prevent normal tailgaters from spoiling the journey home.
Friday morning - still no tailgaters but then I might not see them. Smoke only when engine accelerating under load. Not much smoke if I sit in neutral and rev the engine. Engine spools up to 4000RPM in the normal time.
Friday evening - managed to get a look under the bonnet. Oil has been coming from the dipstick tube and the oil level seems high. (I had the oil changed a couple of weeks ago). Nothing seems loose. Unable to check hoses. Smokey journey home. Took car to local (independent) garage for them to look at on Monday.

This week:
After significant messing about by local LR parts supplier, no real progress. They were unable to even identify the part numbers of any hoses that might need relacing and have refused to give local garage any technical assistance. Local garage took car to nearby LR specialist. On the trip the engine warning light was apparently flickering on and off. Diagnostic computer shows error code P1E30. This, I am told, indicates a shot boost pressure control valve on the turbo. Craddocks and the local LR dealer both agree that will mean a new turbo unit at over £1000 as the valve cannot be replaced without the turbo.

Mopped up tears and repaired nearby breakables. Decided to ask for help on here. Am I out a turbo? Could this all be due to the breather problem mentioned elsewhere? There is no record of the car having a turbo replaced before so I guess the error code is not an old uncleared one. Any other ideas?

Hi Topknot ,sound very much like the same fault i had ,i'm assuming its a td4, check out black smoke by myself, it twas an easy fix it is possible youve stuffed ya turbo,but very unlikely, the other problem ya have with ya oil ,again sounds very much like the de-compresion filter is shagged,again think its in that same thread ,again a very easy fix, if its not the td4 then ignore all i told ya ,hope this helps ya,and best oh luck earthling. . .

Silly me...

Yes, it is a 2002 TD4

Thanks
Pete

OK, so, The garage replaced the breather filter thingy (What is its proper name?)

Oil no longer comes from the dipstick tube but - still plenty of black smoke, sounds of air rushing and lack of power, engine warning light on under heavy load. Garage washes their hands and suggests I take it to a LR specialist. Thank you very much but they at least don't charge me much.

Next I have a (remarkably good) mobile LR chap out who took all of ten minutes to find that the turbo output hose has de-laminated and a flap of liner is obstructing the flow of air. We pull out the entire lining and replace the hose to see what improvement it makes. After blowing through some oil, the smoke is reduced to a grey haze and power is pretty much restored. We decide to leave it like that until a replacement hose can be fitted.

Four miles down the road and the power drops, smoke returns. All this is intermittent. A couple of miles later and the whol slow smokey thing is back properly. Suspect the now weakened hose so nurse it back to base, poisoning the owners of a number of lesser vehicles on the way.

While starting to replace the defective hose, it is immediately apparent (at least to the eagle eyes of my new hero) that the intercooler output hose has let go, unaccustomed as it had been to the kinds of pressure levels now available. Blew a 3cm tear. Quite impressive really. I had no idea there was so much pressure in the damn things. Taped that over to allow the vehicle to be moved back onto my drive. Will go to local LR dealer for a couple of hoses in the morning. Best to replace both the potentially weakened hoses now. The intercooler input hose seems to still be pretty firm.

I will post progress so that others can learn from my misfortunes.

Righty ho...

Went and got the two new hoses this morning. Quick and easy to fit.

After a few minutes, the smoke went away - much better. But....

Now I get poor performance. Low revs seem OK. In neutral, flooring the throttle brings the revs up to 4000+ in a couple of seconds. Thus I suspect the MAF is fine. I can hear the whine of the turbo so that seems to spin up OK.

As I accelerate, all is ok until about 1800 RPM. car won't pick up. Very dead until about 2500+ RPM. At the same time I am getting sucking/blowing noises from the engine during this phase. These noises don't happen when the engine is revving freely.

So I am thinking that either I have another dodgy hose somewher that was OK until I put in the new ones or the Turbo boost actuator thingy is shot and the turbo is not delivering enough of a boost. This last seems unlikely to me because it did, after all, manage to blow out the intercooler output hose yesterday.

I guess I will try disconnecting the MAF and try the disabling the EGR job.

Anyone any other ideas before I trade it in for a different set of problems that will, at least have a warranty attached?

Pete

Hellow and welcome Pete!
Just a thought did you check the short 90 degree hose at the EGR,Apparently these are the ones that usually split first (according to the dealers).
While you have that hose off its easy to see how gunged up the EGR is.
good luck!

Could be fixed now.

I had replaced both the intercooler output hoses and noticed how much gunge was in the EGR unit.

After a good read about and some serious sulking I decided to try disconnecting the MAF top see what would happen. While I was at it I turned up a little plug for the EGR vacuum tube - just in case.


After a bit of fiddling, I finally managed to get the air filter lid off but could not work out exactly how to pull of the MAF plug without risking dome damage. So I had a peek about while thinking. Waddaya know! the lower end of the plastic part (name?) that takes air from the MAF to the turbo inlet had not been pushed on properly.

I guess that air was getting into the engine but the MAF told the ECU there wasn't enough and it restricted the fuele - or something like that.

Anyway, I fitted the plastic doodah properly, put it all back together and went for a run. What fun! I had my engine back. Had a bit of a boy racer session around the local lanes and I am now pretty happy. At least with the engine.

Since this cannot all have 'just happened' - it started with the breather valve filter clogging up - I wonder how much performance had been down without me noticing. I shall have to check fuel consumption now as I only average 27-28 normally. Rather less than promised by Land Rover. My previous Freelander was a 1.8 petrol and that did exactly what was quoted on the published figures.

Now, so long as my injectors hold together....

Fingers crossed

Pete

here is a picture of the longer intercooler output hose to show how it had a hole blown in the side...

Oh!!!!
Thats a nasty gash!!! as the actress said!
