    Hello. Today, February 26, in cold weather - 16 degrees, after traveling about 1 km, the oil light came on, I blinked 3 times, I thought the car was going crazy from cold, I drove another 500 m and the same again with the fact that the engine turned off. I pulled aside, raised the hood and checked, and all the oil on the engine (as if it would splash while driving). Drought on the dipstick. Of course, I didn't start the car anymore. Does anyone know if this could be a serious matter, or maybe some oil pan etc? In the evening I will call a tow truck and take him to a mechanic, but now maybe someone has an idea what would be the reason? Please help.

    Unfortunately, I don't have good news for you, you've probably stopped the engine.
    These engines do not like to use them at low temperatures on short routes (anyway except all air-cooled).
    The culprit is water from flue gases (this is not about the gasket under the head), the water condenses and creates something like oil with oil.
    This liniment clogs up everything you can and the rest of the oil leaks through every hole (thanks to the pressure in the crankcase).
    And if you don't have enough, instead of oil in the oil pan, the ice rink.
    In my opinion, look for another engine if you care about time, because this one should be taken apart to find out what needs to be replaced (bearings, shaft, rollers, tappets, oil pump, rings, pistons and a few other things along the way).
    And finally, this remark for the winter for everyone "we are pounding cigarettes from the shoe."

    Let it not be what you write ... It's a pity this engine because it has only been driven 110,000 I called the mechanic, I presented him with the situation, he claims that he has pneumothorax. I did not go for cigarettes but to work unfortunately ... Thanks for the answer.

    What is the possible cost of replacing this pneumothorax? Is it cleaning? Are you orientated

    Emphysema is not a problem in this case.
    The problem is the lack of oil.

    the engine shut down in time

    It did not turn off, just blocked the shaft on the main shells. This is not a modern excavator etc. that lack of oil or coolant will turn off the engine.

    Car for pickup. This frozen emphysema turned out to be. cost PLN 300 Thanks for the help!

Topic summary

✨ The discussion revolves around a 2001 VW Polo 1.4 experiencing an oil leak and blinking oil light in extremely cold weather (-16 degrees Celsius). The owner reported that after driving 1 km, the oil light blinked three times, and the engine subsequently turned off. Upon inspection, the engine was found to be devoid of oil. Responses from other users suggested that the issue could be related to a frozen pneumothorax (a term used in the discussion) causing oil to leak, and emphasized the importance of regular maintenance to prevent such problems. The owner later confirmed that the issue was indeed a frozen pneumothorax, which was resolved at a cost of PLN 300.

FAQ

TL;DR: VW Polo 1.4 winter oil blowouts often trace to a frozen odma/PCV; preventive cleaning is a 3‑minute task—"It takes three minutes." [Elektroda, Anonymous, post #17064845]

Why it matters: Quick PCV care can prevent oil starvation, warning lights, and costly bearing damage.

Quick-Facts:

Quick Facts

What likely caused the oil leak and flashing oil light on this VW Polo 1.4?

In the discussed case, a frozen crankcase breather (odma/PCV) caused the issue. The blockage raised crankcase pressure and expelled oil. After thawing and cleaning, the owner collected the car. Reported fix cost was PLN 300. [Elektroda, wda31, post #17074176]

Why does a frozen odma/PCV push oil out the dipstick?

If the odma freezes, crankcase pressure rises. Oil escapes via weak seals or the dipstick tube. One member called it "oil dumped through the bayonet". [Elektroda, Anonymous, post #17064813]

What should I do immediately if the oil light blinks and I see oil?

Stop safely and shut the engine down immediately. Do not restart. Arrange a tow and inspection. Oil starvation quickly ruins bearings and other parts. [Elektroda, urkotrebor, post #17064787]

How much did the fix cost in this case?

The reported cost to resolve the frozen odma was PLN 300. This covered diagnosis and restoring the breather’s function. [Elektroda, wda31, post #17074176]

How do I clean the odma/PCV in winter?

Do a fast de-ice clean.
  1. Gently tap and shake the vent tube to break ice.
  2. Clear the baffle outlet of sludge and condensate.
  3. Refit hoses and confirm free flow. "It takes three minutes." [Elektroda, Anonymous, post #17064845]

Should I install an odma/PCV heater?

A member advises against heaters for the odma. "Forget about pneumothorax heaters, throwing money away." Routine cleaning worked for them, even with Webasto. [Elektroda, Anonymous, post #17064845]

Can the engine seize from this?

Yes. With no oil, the crank can seize on main bearings. The engine will not shut itself down first. "It did not turn off, just blocked the shaft on the main shells." [Elektroda, ociz, post #17067611]

Is it safe to refill and drive after oil has dumped out?

One member refilled with three liters and kept driving. They reported over 80 km without issues afterward. This outcome is not guaranteed for everyone. [Elektroda, Anonymous, post #17067663]

What damage might oil starvation cause?

Running dry can damage many components. Expect damage to bearings, crankshaft, rollers, tappets, oil pump, rings, and pistons. A teardown may be required to assess repairs. [Elektroda, urkotrebor, post #17064787]

Is this issue common on VW 1.4 engines?

Members report frozen odma as a recurring 1.4 winter issue. One comment notes, "Constant engine trouble 1.4." Prevention focuses on keeping the breather clear. [Elektroda, Anonymous, post #17064813]

What symptoms did the driver see before stopping?

After about 1 km at −16°C, the oil light blinked three times. Oil covered the engine, the dipstick was dry, and the engine stopped. The driver chose not to restart. [Elektroda, wda31, post #17064485]

Does short-trip winter driving increase the risk?

Yes. Short, cold runs increase crankcase condensation. Emulsified oil and sludge then clog passages and the breather. These engines dislike short routes at low temperatures. [Elektroda, urkotrebor, post #17064787]

I have Webasto. Do I still need to clean the odma?

Yes. One member still cleans the odma weekly despite Webasto heating. They tap the tube and clear the baffle outlet in minutes. [Elektroda, Anonymous, post #17064845]

If I see oil on the engine, could it be the sump/pan?

In this case, a cracked sump was not the cause. The frozen odma forced oil out under pressure. Fixing the breather resolved the problem. [Elektroda, wda31, post #17074176]
