Smoke Coming Out of the Oil Dipstick – How to Fix?

Smoke coming from the dipstick is not unusual. If you are driving long distances in your car, the crankcase is under pressure, which can cause smoke to build up on the oil dipstick. However, excessive smoke may be a sign that the engine is having other issues. 

When coolant or oil is leaking into the combustion engine, smoke can be produced. Wearned piston rings and blown headgaskets are the most common causes for smoke from oil dipstick. 

We will discuss in detail the causes of smoke from dipsticks.

Is it possible for smoke to escape from my oil dipstick?

First, check the smoke. don’t open the cap when it’s hot. This could be very dangerous.

1. Piston rings that are worn out

The piston rings carry heat from the hot piston towards the cylinder walls. It keeps the in-cylinder air tight between the piston wall and the piston. A mistake in the combustion process could lead to the accumulation and condensation of oil. 

This can lead to wear and friction in the piston rings. A crankcase blow-by can occur when the pressure rises due to wear on the piston rings. Incorrect functioning piston rings can allow combustion gases to enter the crankcase. You will see white smoke from the oil dipstick.

Damaged Piston Rings: Signs and symptoms

1. Excessive oil consumption
2. Poor engine performance
3. Smoke from exhaust can be either white or gray.

Fix

Replacing the piston rings is the only solution. Prices for parts to replace piston rings range between $75 and $100. Labor costs range from $1,800 up to $3,500.

2. Coolant leaked in the engine oil

Coolant evaporates once it enters the hot-combustion engine. White smoke is formed when this evaporation occurs. This smoke can seep into the dipstick tube.

The most common reason for engine coolant leaks is a cracked or broken head gasket. Overheating of the engine can cause the headgasket to blow. Coolant in the combustion engine can also leak from the radiator due to corrosion. As the radiator ages and becomes clogged, this can happen. 

Coolant Leakage in the Engine Oil

1. On engine oil, a milky gravy-like substance
2. Overheating
3. Sweet odor
4. Engine misfire

Fix

It is possible to replace the head gasket if it has burst. Head gasket replacement costs can run between $1,000 and $2,000 The cost of replacing the head gasket can be anywhere from $1,000 to $2,000. 

Tips to help you avoid smoking coming from the oil dipstick

These are some tips to help prevent smoke from getting on your oil dipstick.

1. Verify that the coolant is working properly and that the engine is not heating up.
2. Check that the headgasket is correctly installed.
3. Make sure your engine oil is clean and changed often.
4. To avoid premature wear, clean the piston rings.

Conclusion

It is also important to pay attention to any smoke on the oil dipstick. This could be a sign that the piston rings have worn down, causing the blow by in your engine. A blown head gasket could also be the reason for smoke on the dipstick. 

The oil dipstick may have smoke, which can cause the engine overheat and misfire. It is best to have the damaged parts replaced by a mechanic.
