Audi A4 B5 1997 1.6: White Smoke on LPG, Overheating, Gasket & Power Issues, STAG Gas, NKG Candles

Hi, I have an audi a4 b5 1.6 from 1997. I bought them in August as the first car for a young driver. The car seemed to be around 176 thousand I think that the course was authentic because the previous owner had them 11 years and it was obvious that it was 2 cars because the seller rode in delegations but to the point after 2 thousand km enjoying the car, engine overheating went off. I arrived home about 20 km but probably with 5 stops so that the engine would cool down and refill with coolant. Of course, one of the worst decisions in my life for a young driver. Diagnosis gasket under the head. The timing was additionally replaced and everything was to be played so I added STAG gas to it due to good feedback and everything played but the next symptom was jerking and losing power which was helped by changing wires and candles (NKG) And now after another 4,000 km another the problem is white smoke from the exhaust pipe. I heard that the engine after replacing the gasket can 'eat' some oil so I did not worry about it, now I flooded the valvoline maxlife 10w40 and for now with the oil has gone from what I see. What could be the cause of this white smoke? I will add that the gasoline is okay and I noticed that on LPG above 5-6k revolutions also the smoke disappears.

in VAG the liquid temperature pointer moves from the 90-degree line when the engine is over 105 degrees, also you probably overheated it very decently then. It can be vindicated.

If they are white smoke and not gray-blue, then I would look for a reason further in letting the cooling liquid into the sleeping chamber, but the question which way. Check that the cooling hoses are hard after driving and that you do not lose the refrigerant fluid.
There is also a chance that after overheating, the evaporator releases water to the gas. Especially if you say that this happens only on LPG.

Did you plan your heads or just replace the gasket?

If fluid and oil are not decreasing, and the ones that are mainly on LPG are poor gas quality (moisture) and / or poorly regulated installation. Does this smoke smell? Both oil and coolant have very characteristic odors. The oil gives rather blue smoke, white is water or coolant. I hope that after replacing the head gasket, you replaced coolant and oil. Has the head been inspected / checked before the new gasket was installed?

I did not plan the head, there was only a gasket replaced. Thank you for the advice I will check these snakes tomorrow and see. Yes, after changing the gasket, the oil and liquid were also changed. I do not think it was the evaporator's fault because the gas was installed after replacing the gasket.

Usually, after removing the head, especially if the gasket was burned out and / or the engine overheated, it is necessary to plan the head. Otherwise the replacement of the gasket is pointless - the fault will return after several hundred / several thousand. km. The minimum is to check if the head is not "warped".

I mentioned it I think that a decent mechanic (after knowing) so probably checked whether the head is suitable. I checked today the fluid you see small cavities is below a minimum of 0.5 cm I think that the cavity is somehow in the limit of 1cm per 1000km, because it was a little above the minimum as I checked last time I will add that I like to speed up. Today, on a quiet ride to 2.5-3k revolutions, smoking was light in the city from morning and it was ok in the afternoon. I would add that after driving after opening the mask you could hear gentle dripping facing the car somehow behind the engine on the left more. Do you think that smoking on LPG with engine load accelerating 4-5 k revolutions can be caused by damaging some hose?

I do not know if it is possible but I think one thought, the reducer is heated with a cold liquid, so it can jam and little fly injections. That would explain the gasification on LPG.

In a functional car, the fluid has no right to dispose of. Some construction reducers have the ability to release the liquid into the intake. Sometimes it ended with the replacement of the engine, because there was nothing to repair ...

Can I somehow check if it's the fluid that gets through the reducer and that's why it causes smoke? Because the engine does not see me for the time being, especially since I have 4 months and the engine has 180,000.

If the engine continues to "smoke" in white and these are not the faults described above, then I suggest giving a car to a mechanic who will perform a head test for a fracture.
In the son's car it was only the mechanic who determined the break of the head for the third time, the previous 2 did not perform the check, but the money was counted.

How did the case end? Because a friend has similar symptoms.
