Experiencing Heavy Smoke in Cold Weather from Soothing Blue 1.9 TDI Golf 4, Engine 90 km ALH

Question

Hello . I have a problem from somebody
Time with my golf 4 engine 90 km ALH. It smokes very hard when it's cold, I have to hold on the starter for some time, and if it catches a swirl of blue smoke, and then white. I would check the injection angle, the amount of fuel, the glow plugs, and everything in the best order. The diagnostician recommended me to replace the injection pump, but I want to advise someone who had a similar problem.

HELPPP !!!

Please enter in order: - compression pressure value, - injector overflow test result, - value of current consumed by glow plugs during cold start.

Hello, I have the same problem only that the Audi 1.9 TDI 90 km pump I had sealed and regulated and the problem is still ... I noticed that not only on the cold only as it stands so with 3 hours it already has a problem. After a night stop, as long as he turns and starts up, all you have to do is put it out and I start it again without a problem, so I think that something with fuel, that he runs away somewhere for a long time ...

This is how it looks like the fuel is coming back. Take the test, plug the fuel in the bottle, light up a bit, let it go out and turn off in the morning and see if it fires the shot.

All in all, I put a transparent tube on the pump's supply cord to see if any blisters are being made. If it goes back, this bottle probably won't do anything ... But can I try connecting it to the pump?

Yes, only today at my friend's, he connected his computer, and so: Injection angle I had very high, as much as 70, changed me to optimal, i.e. jumps 42-48 The fuel dose is at 3.0-3.2 (it's perfect because it was 1.0, he had a little bit bigger kick, but he jerked in gears like a possessed person, now nothing!) We checked the fuse and glow plug strip with a meter, and it turned out that there was no electricity ?? (I paid the mechanic to check me professionally and said that it is perfect), we changed the fuses, and the current goes to the strip. And now yes. At kata 42-48 it is difficult to smoke even when warm, but it should be like that. (I add that the fuel does not go back because we checked)

Alansi007 · Answer

Gentlemen, save me! Maybe someone had something similar ??? !! ??

migmig85 · Answer

And the fuel temperature sensor in the injection pump ?? I used to have such a case.

Gentlemen, I found something like this.
Black smoke - unburned fuel (e.g. pouring injections)
Blue smoke - oil in the combustion chamber
White smoke - water in the combustion chamber, in other words the gasket released under the head EPA.
All you need is a small leak and you can change the half motor

.
Maybe try to go this way?

Alansi007 · Answer

Gasket never, I have a new one because I replaced pistons a month ago ??

krzych1-b · Answer

I would still look into the timing setting, if everything is set to tip-top, because something does not suit me with these fumes. I used to have a valve in the volvo supported and a turned down shell on the crankshaft - but you would hear a knock and a cloud of smoke behind you
One more question . Did you check the candles individually, i.e. dialed and plugged into the charger, for example, and when do they heat up?
Just that one of the candles is already finished (or finished) and then it starts to catch the temperature, then you have trouble starting the engine and there is smoking (unburned fuel).

Alansi007 · Answer

With this timing, I have it perfectly set, because I would hear that something is wrong. With candles there is such a miss that I had a burned candle fuse, it is replaced with a new one, but the strip that gives the current to the candles, at the last candle is broken, and does not reach the candle. This may be the reason. I will add that at start-up after a night, and possibly after 4 hours of awful awfulness to Niebeisko

krzych1-b · Answer

If there is no connection with the last candle then you need to fix it, at least you will eliminate the next fault.

I will return to the color of smoking.
Leaking or faulty valve seals cause oil to drip into the engine from the valve stems and hence the smoking !!!
- Turbocharger failure or oil suction via pneumothorax (it can be replaced cheaply), unfortunately turbo repair is more expensive. With a damaged turbo you have a decrease in power, which can be felt immediately after the appearance of smoke.
- engine idling means cylinders {but as you replaced pistons, you also honed and honed cylinders}
- air filter, it happens that its contamination causes the emission of blue smoke. In old cars, this means high engine wear. But here you probably have clean.

Alansi007 · Answer

* The strip on days will be replaced

* turbo is ok It pulls up nice, there is no loss of power or anything related to it

* pistons were replaced, the whole head checked, new gasket, also in this direction I would not go.

* As for the air filter. It was replaced a year ago, I checked some time ago and is a bit dirty, there is no tragedy, but after a year it is time to pass, but I think that this is not the reason for such "VERY" heavy firing.

krzych1-b · Answer

Pistons made or rings you have new, but I also meant cylinders. Made-Yes? If so, the compression is -hmm :?:

Did you reach valves or were they just checked for leaks?
Sorry to ask, but I'm starting to run out of reasons for this smoking.

Alansi007 · Answer

Pistons and rings new, so it's ok, compression is, it would be smoking from the bayonet The valves were not checked and not run in

krzych1-b · Answer

I have a request, answer all questions or suggestions because I am crazy. Have you looked at emphysema?
And the fact that it burns heavily, it is the fault of the unplugged candle - they need to heat four and fire into four cylinders, because despite the fact that the engine fires in three, HE burns only in these three cylinders - no and telepiece engine. in cold weather, like good compression, the engine will start without a problem.

Added after 40 [minutes]:

And one more thing because I forgot to write - very important. Replacing rings and pistons, without sanding or honing the cylinders, only makes matters worse.
How many kilometers do you actually have on the meter?

Alansi007 · Answer

Odma is fine, it was checked, and as for the cut, the head was not ground, because it was already sanded twice (from the previous owner), so the mechanic give a larger seal.

220,000 are driven, but I dare say it was distorted ??

krzych1-b · Answer

I don't think you have a cracked head somewhere near the oil channel (darkest scenario)
If he is a friendly mechanic, he should do the renovation well, my suggestion is this: I bet on the leakage of valves (valve stems). He did not exchange for new sealants.
And take to heart what you got at PW from me

Alansi007 · Answer

I also don't think it's the reason for a broken head. It was tested and I have known the mechanics for quite a long time. I will check these valves in a week, maybe that's where the problem lies
