How Long Will An Engine Last With Blow-By?
If you are a regular vehicle user, then for sure, engine blow-by is something you don’t want to face. Unfortunately, though this may happen for various reasons, there are few solutions to that.
But most people don’t know how much your vehicle can run/engine last with a blow-by.
So today, along with the reasons and solutions, we will figure out how much your engine will last in this situation.
How long will an engine last with blow-by?
Usually, an engine goes for approximately 11,000 hours if somehow blow-by occurs.

However, this depends on the type of engine. Sometimes the blow-by became so severe that it became tough for the machine to last so long.
What is blow-by?
An engine usually has its processing way. But if somehow extra air goes into the engine through the piston ring, the problem occurs.
In short, when the fuel of a vehicle and compressed air get in touch, then blow-by happens. This kind of situation may occur for various reasons.
Common symptoms of blow-by
As it’s a severe issue, so it’s essential to realize the symptoms. So here we share some common symptoms through which you can understand the problem-
Smoke In Blue Color

If you see blue color smoke is getting out from the pipe, then it’s a severe symptom of blow-by.
This usually happens when the fuel is not remaining in its raw form. So it would be best if you kept a clean eye on that.
White fumes
If you see white fumes are getting out from the tailpipe of your car/vehicle, then indeed, it’s warning you about blow-by. If somehow the combustion chamber gets in tough with water, this will occur.
Failure Of The Engine

We hope you understand engine failure may happen due to many things. From that many reasons, you can consider blow by as one reason.
So if somehow you face an engine problem, you better examine a bit to find out the actual reason.
Engine oil issue
Okay, every single thing has its characteristics. But if you see coolant is getting in touch with engine oil, something is undoubtedly wrong here.
Usually, this indicates that something internal is not working correctly, which might blow by.
Sound from the engine
Though it’s prevalent for vehicle users. But sometimes these engine sound end up with a blow-by. So if somehow you get to hear these, try to check out the reasons.
So these are the common symptoms of blow-by. If somehow you realize you are facing one of them, try to solve it as soon as possible.
Reasons Behind Blow-By

You already know the symptoms, so better now you go through the reasons behind a blow-by. Read the reasons carefully and make sure you avoid them-
The problem in the cylinder wall
A cylinder wall is something that protects the internal things. But somehow, this gets damaged, then it causes blow-by in most cases. That’s why it’s essential to look after the cylinder wall.
Ventilation hoes issue
The ventilation hose plays a significant role in keeping things cool down. But if somehow the hose becomes blocked, it will indeed cause a problem. As far as we saw, this creates blow-by.
Damaged piston rings
Pistons rings sometimes get in touch with the cylinder, ending with a finished piston ring.
If this happens, then it causes gas leakage. We hope you understand gas leakage is a significant reason behind bow-by.
Though there are many other reasons, we tried to uphold the most common ones.
Process Of Fixing This Problem

As it is becoming a big issue, that’s why now we will try to know the process of solving it-
Clean the ventilation process
As you already know, how much the ventilation process matters, so make sure you clean the entire crankcase. If you find anything which is blocking its way, then wash it.
Try some oil
In some cases, we see that piston rings get stuck. So if you manage to find this issue, you can try oil on the cylinder. Diesel will smoothen the process, and piston rings won’t get stuck anymore.
Change the piston rings
Okay, if somehow the piston rings are not working correctly, then you better change them. As it’s a challenging task, you better take help from someone who knows it well.
Try a giant cylinder
If you think cylinder size is becoming an issue, then it’s time to try a bigger one. Sometimes, you may have to work with the engine block. Change it, if needed.
Dear readers, if you somehow face this problem, you are requested to follow these solutions. Then, hopefully, you will get rid of it.
FAQs
Is Blow-By Bad For Your Engine?
As we can run the vehicle despite having blow-by in the engine, we don’t take it seriously. But the fact is, if this remains for a long time, it will damage the engine. Thus the engine will lose its capability.
Can Too Much Oil Cause Blow-By?
Technically this can happen because of too much oil. If you put extra oil in the crankcase, this will result in a blow-by after some time. So better you don’t put too much oil.
How Long Should Piston Rings Last?
The time is something which depends on how you are using it. If you can use it properly, it will hopefully last between 1,00,000- 2,50,000 miles.
Is It Worth Replacing Piston Rings?
If you can replace it, we will indeed suggest you to do so.
If you can manage to replace it, it will keep your car in a better form. But, most importantly, the vehicle’s capability will increase a lot.
Conclusion
If you consider one of the serious problems your engine may face, then bow-by is one of them. So instead of asking ‘how long will an engine last with a blow-by,’ you better solve this one.
Because the more you will run your vehicle with this problem, the more your engine will lose its power.
