Audi A3 8P 1.6 - Takes 2 liters of oil per 1000 km - video + photos

Hello, recently my Audi A3 8P 1.6 with LPG, 2004, started to take oil, and it's gigantic amounts - liter per 500 km. I noticed the problem after installing LPG, but this is not necessarily the cause of the problem - I was only two months old before the assembly, so maybe the dealer just flooded it with some kind of motoctor that stopped working just after the LPG installation? Of course, after the purchase, filters and oil were replaced, funnel 5w30. There are signs of leaks on the engine, but are they so significant that a liter of oil goes on 500 km? I have marked "critical" places in the pictures. Oh, the car is smoking, but it is white and it seems to me that it is in the cold rather than all the time.

In the first video, you can hear a sucking sound from under the oil filler, a whistling sound.

In the second video, a strange thing, I don't know if it matters - when the revs drop, the pointer stops for a moment at ~ approx. 1150 RPM, then continues to descend.

I will be grateful for your help and possible advice on where the problem may be, and where certainly not - of course, I intend to go to the mechanics, but I want to know the opinions of objective forum users first.

You have opinions about it on the web, rings in general.

Apparently so, but I also find opinions about, for example, the head gasket. So a general overhaul of the entire engine?

Oh, and will measuring compression in the cylinders confirm the diagnosis that they are rings?

I raise the topic, questions as above.

No head and no pressure measurement. These engines by their very nature sip oil, just not that much - it is probably already heavily worn out. If it does not release the blue cloud right after firing it, unfortunately, the bottom of the engine will be overhauled and the rings themselves will not work.

Mileage on the meter of 186 thousand, but the actual figure is 260 - they checked it on the computer during the LPG assembly. And do you have to overhaul it "now", or can I still drive a few thousand km, collecting and refilling this oil, without fear that the engine will jam?

As long as you add oil, the engine will run.

Thanks for the information.

Engine with defective 3-piece rings - blow them out and install usually one-piece ones

Today I called the mechanics. Is it true that in order to measure the compression on an engine with LPG installed, you need to change the intake manifold gaskets? They also mentioned candles, but what could they have to do with taking oil?

The compression pressure is measured by measuring the compression pressure in the cylinders, not in the intake manifold. Candles, as they are a consumable part, it is easiest to say that all the faults of the candles, unfortunately in this case, have nothing to do with your problem.

They found that the collector had to be dismantled to measure the compression. For this computer diagnostics, these candles ... I think they want to stretch me: /

I do not know if you saw what this engine looks like ... access to the candles is difficult due to the intake manifold. If they are new, it is also worth replacing (all eight) - they are probably hard as stone

Here, the pressure measurement does not always show the rings .... Here, the facts of the vw group, i.e. the rings mainly ...

Hi, today the mechanic wrote back to me regarding the scope and cost of diagnostics:

Quote:

The basic operation from which you should start checking the car is: computer diagnostics of the engine and compression control with simultaneous checking of the spark plug condition (with spark plug replacement). This operation requires the removal of the intake manifold. When reassembling, it is recommended to replace the intake manifold gaskets. Of course, we will also check engine leaks, if any.
The cost of such diagnostics is: PLN 270
Plus the cost of the material

1. Intake manifold gaskets 4x15 PLN + 4x7.5 PLN, a total of 90, - PLN

2. Spark plugs set. 4 pcs depending on the chosen option from PLN 100 per set.

What do you think?

Take out the bike and make these rings and new bushings by the way. Look for a good, recommended grinding plant in the area (write where you are from, someone can recommend something), and so you will spend PLN 500 for the diagnosis of the corpse that he is dead. From this he will not stop drinking the oil. TTTM This Type Yes Ma.

I have recently made such an engine, the oil scraper rings are 3 pieces, they stick in the piston grooves and stop fulfilling their function

In my golf with the same engine, I replaced the rings on MAHLE 82.5 STD 1.2-1.5-2, replacement of valve seals and no more adding oil ...
Polish Prima are also good and much cheaper ...

There is no point in making panewek as good.

He will unscrew the cranks anyway.

5w30 for such a gas engine? Pour over 5w50 or 10w50. Checked with me on several cars.

Gentlemen - is it worth going into this renovation? Because if I have to pull out the engine to replace the rings, it will be worth doing other things as well and I will probably pay with 3-4k. And for 3000 I can pour and pour this oil ... Because I think there will be some costs in addition to the rings?

Not that I regret the money, because I have already put a bit into this car, but calculating it cold ... Maybe it's better for these 2-3 years (I would like to drive) just pour this oil?

Or maybe the problem will get worse and the costs will increase even more? I am asking as a layman, so please be understanding.

The problem will get worse, you will "kill" the catalyst and the lambda probe and these are not cheap things either.

2 liters per 1000 is just a renovation ...

And only a full renovation saves me, is a small enough?

Replacing the rings plus checking what's in the head, certainly planning it plus sealants. This is the minimum you need to do. Get ready for around PLN 2,500. Timing when to replace? New candles, eliminate leaks, even around PLN 3,000. will come out during work.

I always buy a bollard, renovation is not profitable in this year, so it is 20l of rolling wood.
And replace the pneumothorax, don't isolate.

... that's the only question - will the found post be better than the one you have?

It's so good that I have recently assumed the timing, only about 10k I have driven on it.

Anyone know a recommended workshop in Wrocław?

I contacted the mechanics, so far they are proposing to replace only the seals for about 550 PLN - expensive?
