5 Symptoms of a Bad Oil Filter (Clogged, Leaking, or Wrong Type)

The oil filter has the crucial job of filtering the oil that lubricates the components of your engine. As oil circulates through the engine, it picks up contaminants and debris along the way. You’ll want to keep these contaminants out of the engine to preserve its lifespan.

The only way to keep these contaminants from harming engine components is to have an oil filter which can prevent them from entering the engine in the first place. The engine depends on the filter just as much as it depends on the oil itself.

If you had no oil filter in your vehicle, then the contaminants will build up rather quickly inside the engine. This will create a whole lot of functionality issues in the engine and the vehicle.

Top 5 Bad Oil Filter Symptoms

Most of the time, you’ll want to replace your oil filter at the same time as when an oil change is being done. But sometimes, it’s ok to replace the filter at a slightly longer interval.

However, if you notice certain symptoms occurring in your vehicle, then it will be a sign that you do need to replace your oil filter with a new one. Otherwise, you could risk permanent damage to your engine which will cost thousands of dollars to replace.

Below are five of the most common symptoms of clogged or leaking oil filter in your car. You may even have the wrong type of filter installed which could be causing problems.

As soon as you recognize these signs, get to your local auto parts store to buy a new filter and switch it out or get your vehicle to the nearest auto mechanic or quick lube place so that they can replace the filter for you.

1) Engine Overheating

Like your air filter or fuel filter, your oil filter can clog up if left in there too long. With an oil filter, this could be an even worse problem because it may prevent oil from being able to enter the engine altogether. Once that happens, the engine will not receive any lubrication for its moving components.

As you know, the friction between the metal components will generate heat quickly. If this heat cannot be cooled by the oil, then it could lead to the engine overheating. You will often see the “Check Engine” light come on when this happens.

2) Weak Performance

The performance of your vehicle will tell you more than enough. If contaminants are building up in your engine because the oil isn’t being filtered properly, then it will diminish the engine’s ability to generate power for the vehicle.

This means that when you step on the gas pedal, your acceleration will be reduced or nonexistent. As you continue to let this problem go unfixed, the performance will only get worse.

3) Dirty Exhaust Fumes

Take a look at the exhaust fumes coming out of your vehicle’s tailpipe. Can you see smoke coming out of the tailpipe? If the exhaust looks gray or blue, you have an oil burning issue. This is sometimes the result of a clogged oil filter causing oil to flow into your exhaust system where it burns up.

You may even experience a burning odor inside your vehicle from this too. These are very obvious signs that you need to replace your filter promptly.

4) Low Oil Pressure

The dashboard of your vehicle should have an oil pressure gauge. In normal situations, the gauge will show a consistent amount of oil pressure that will never change. But if you see the oil pressure dropping erratically as you’re driving, then you definitely have a problem with your oil pressure.

One of the causes of low oil pressure can be a leaking or clogged oil filter which is preventing the flow of oil from going into your engine.

5) Metallic Noises

When oil is prevented from entering your engine and all those metal components grind against each other, all that friction will cause two things to happen. Like previously mentioned, it will cause the engine to overheat.

But it will also cause a lot of metallic noises to occur as a result of the grinding. These noises should be very easy to hear as you’re driving. When this happens, the internal components of your engine are wearing themselves out and causing damage. Check your oil level and filter to make sure one isn’t the culprit.

  1. My car is hard started in the morning. After it has started and idled for minute or so, the engine initially fails to pick even if I press the gas pedal. Is this a sign that my oil filter is clogged? Thank you

    • Could be the oil filter, oil, or a variety of other issues. Unfortunately, needs more info. I would suggest scanning for any error codes stored in your car’s computer using a diagnostic tool as the first step in diagnosis.

  2. I’m embarrassed to say but my Kia needed an oil change but I add oil myself. While driving, my car started to making a grinding noise my oil light started flicking off and on and my car shuts off with no smoke but won’t crank up. What can be the problem? Thanks

  3. Could a clogged or old oil filter, cause a car to jerk when taking off and blow a big puff of smoke ? Not ever time. Just after driving 100km for atleast 30km or more

  4. My Honda Odyssey 2000 started to overheat and I noticed that I don’t have to let it set before checking oil dipstick , it isn’t moving up the stick , hopefully it’s a clogged filter from Valvaline Instant Oil Change so I guess trying fram filter before anything else , I have no idea where to get to the oil pump and can’t find anything on line for it ! Wish me luck !

  5. I think you can understand what I stated ? Sorry I have been thinking about this issue 😔 I hope it’s not a oil filter I should have said but praying it’s not a oil pump either

  6. I have a 04 dodge Durango and it’s nearing 289, 000 miles. Luckily its only needed basic matanice. I do have to add a half to a quart of oil about every 6 weeks or so. Well about 3 weeks ago I heard a beep alarm from dashboard but didn’t get to c n time what light came on and went off. For the last 2-4 days the oil light has been beeping and flashing like crazy but only when I have slowed way down or came to a stop. Once I get going at a steady rate of speed it stops beeping, blinking and the light even goes off.. Engine hasn’t overheated, no kind of smoke coming from tail pipes and it doesn’t die. Im also not hearing a loud knocking noise. The vehicle was my daughters and then I got it from her. I went through log book & realized it’s been 3 & a half years since last oil and filter change. Is it possible that the oil filter is just so clogged that that’s why it’s doing it? Oh and I don’t lose any speed or power when trying to excellarat. Please and thank u for any response.

    • Yes, a gummed up oil filter could certainly be the cause. I wouldn’t expect a loss in acceleration if the filter is clogged, but you would have a momentary drop in oil pressure (probably the reason for the oil light) and this will do damage to the engine over time. I personally would park the car until I could change the oil and filter.

      If that doesn’t resolve the oil light, further troubleshooting is needed. It’s not something I’d let go for a while without finding the root cause.

  7. Hy my hyndai i30 everytime when I start it.it cuts off bt allows me to start it immediately. .sometimes it cuts randomly

  8. I serviced my car but replaced my oil filter with a defected one. After some time there was a weird sound in the engine. I checked it and I replace the defected oil filter with a good one. I still hear the sound what might it be? Can that cause an engine knock

    • If by “defected” you mean defective, I would avoid this in the future. Oil filters are cheap, so unless you’re desperate you should only use a working filter in that’s made for your specific vehicle. I personally would rather leave my old filter on for a while than run with the wrong filter, or no filter at all.

      From the description it’s hard to know what the noise is, but I imagine it’s possible for a bad filter to cause additional wear that could lead to engine knock, depending on why the filter was bad. No filtration will cause additional wear from dirt and debris. Broken parts in the oil system may circulate loose metal through the engine and cause additional damage.

  9. I noticed my Hyundai i45 making a slight rattling noise when I accelerate up big hills and goes away after a bit, and today my oil light turned on when I came to a stop at a traffic light and had to wait for the green light. It turned off again once I took off, but the rattling noise in my accelerator occurred every time I pressed down on it. My oil levels are fine and I change it at home whenever it’s needed, my engine doesn’t overheat. I’m about 1000km away from my next service, could a clogged oil filter be the cause of my oil light coming on despite my oil levels being okay, and could it also affect my acceleration?

    • That oil light is something you should get addressed as soon as possible. Perhaps it’s just the sensor, but you may have low oil pressure even if there’s enough oil in the crankcase. Consider performing an oil pressure test to know for sure.

  10. if we have replaced the oil pump two times and added oil in between……what is the problem………we purchased this truck used an dealer said it was good…test drove it and checked what we would out………..day after signing papers truck made noise sounding like medal….replace pump………..week later same thing saleman was no help had to let it go back we were afraid engine damage might me next thing
