What should I do if my engine oil keeps blowing into the air filter?
Purchase an engine flush formula from your local parts store and follow the directions. In general you will pour the formula into the oil and run the engine for a period of time. Once the engine has been flushed drain the oil and fill it with fresh engine oil. Replace the filter and see if the problem persists.
What causes oil to leak from the air filter?
If it is determined that a clogged PCV valve is the source of engine oil inside your air filter or air intake system, it should be replaced, the air intake should be cleaned, and a new air filter should be installed. 2. Worn Piston Rings A second potential source of engine oil leaking into the air filter housing is due to worn piston rings.
Why does the air filter in my car fluctuate?
The amount of air entering the engine through the air filter is going to fluctuate depending on how fast the engine is running. If you push down on the accelerator, the engine will need more fuel to increase the rate at which the pistons are moved. In order to increase speed, more fuel and air is needed.
Where is the air filter on an engine?
The air filter on most modern combustion engines is located inside an air intake housing, which is installed on the top of the engine.

Why do you have to put a filter on a blow by?
The more surface area the blow-by has to flow over, the cooler it will become and the more fuel and oil will condense. Forcing the blow-by through some kind of filter material or perforated plate also gives the vapors something to smack against and collect on while the rest of the gasses are allowed back into the intake.
What happens when an air filter is clogged?
When the air filter becomes clogged with debris, it can cause the engine’s fuel efficiency and power output to decrease. If oil is found inside the air filter, it can also significantly impact the engine’s performance.

How does a Harley Davidson Top breathing engine work?
Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. It exits through the breather bolts and into the air box where the air is filtered and the oil is captured in the air filter.
How does oil get into the air filter?
The PCV valve is similar to an engine oil filter in that it eventually becomes clogged with excessive debris (in this case — engine oil) and should be replaced as recommended by your vehicle’s manufacturer. If the PCV valve is not replaced as recommended, excessive oil will blow through the PCV valve and enter the air intake system.
Why is there oil coming through the breather?
Normally there will be a bit of oil coming through the breather especially if operated on a slope. Are you frequently topping up? Normally there will a little oil due that is the way the crankcase vent the piston rings blow-by gases.
Is the breather tube from the top of the motor?
My question is the small breather tube from the top of the motor to the air cleaner box exit it’s close to the carb. and puddles some oil in the air cleaner box. Is the carb supposed to suck oil up through the tube or is there some type of defect in the breather system The motor runs strong, Good compression, No exhaust smoke.
What kind of air cleaner do you use on a Harley?
On medium heat & high speed, it’s still way less heat & velocity than the element experiences during normal riding operations. A little 90-100 degree low pressureair (low enough to not compress the fibers, is perfectly fine. Hell, same exact media for diesel rigs, K&N replies you to use a pressure washer & compressed air.
Why is oil dripping from my Harley air cleaner?
Same problem on a 2012 ultra.tried running low oil didn’t work just junk harley internal parts. Don’t blow out with compressed air! You will ruin the element. Shake the filter and them let it air dry. Phooey… As long as it’s not high pressure, keep it to 10-15 psi, it’s fine.
Where does the oil come from in a Harley Davidson?
Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. It exits through the breather bolts and into the airbox where the air is filtered and the oil is captured in the air filter.
Is it OK to blow oil out of air cleaner?
Your new HD should not blow oil out of air cleaner if everything is as it should be. I would take it back and demand something be done. If they won’t do anything, tell them your going straight home and calling HD service. Somebody else will chime in here shortly with more info I’m sure.

What happens if you don’t change your oil filter?
Without this oil, your engine can suffer severe damage. As a safeguard to oil filter clogging, premium oil filters contain a bypass valve which regulates oil pressure within the oil filter. If the oil filter were to become fully clogged, this bypass valve would open allowing oil to continue to circulate into your engine.
What causes oil to come out of the carburetor, air?
A lot of high-performance air filters (still common on small engines such as lawnmowers) use an oiled foam element. If it’s got too much oil on it, some of the excess will be blown out on the downwind (carburetor) side.
What to do when oil comes out of air filter?
Third, top off oil to mark. Fourth, clean the old spark plug with carb cleaner and dry it. Fifth, install old plug and start the engine outside with no air filter, as when it starts you will now have a fogging unit. It may be a little hard to start. Six, let the unit run until the smoke disappears, probably about 10 minutes.

What causes oil in air intake to come on?
A faulty one will cause an imbalance of air flow and send some oil in air intake. It will also cause the check engine light to come on. Cleaning or replacing is the option if one or multiple valves are completely blocked or semi-functional.
How does a dirty air filter cause a misfiring engine?
Misfiring Engine. Restricted air supply from a dirty air filter results in unburnt fuel exiting the engine in the form of soot residue. This soot accumulates on the spark plug, which in turn cannot deliver the necessary spark to combust the air-fuel mixture.

What causes oil to leak from a turbocharger?
When a turbocharger is installed correctly, it should NOT leak oil, however, there can be cases where oil leaks occur. The following highlights some of the main causes and signs of oil leaks. The above diagram shows the correct oil pressure in both housings resulting in no leaks from the turbo.
Why is air blowing out of the oil filler cap?
When you take the oil filler cap off there is a lot of air blowing out, the breather pipe is clear and it has not lost performance and it’s not burning oil. There is no water getting into the oil but the sump seal is leaking and the one above, drips about egg cup of oil on drive every week.
How to avoid common causes of blow by and oil consumption?
Here are some common causes of blow-by and excessive oil consumption and how you can avoid them on your next engine build. The combustion process is never perfect. Even the best street engine never seals all that combustion pressure. A certain amount of cylinder pressure will always find its way into the oil pan.
How does over filling an engine cause oil consumption?
Over filling an engine’s crankcase can cause a loss of oil control and major increase in oil consumption when the oil- and second-rings become overworked and begin to let oil into the combustion chamber. The easiest and least expensive way to minimize windage is to avoid over-filling a wet sump engine with oil.

Why is air coming out of radiator filler?
Someone suggested (when cold) to put my hand over the radiator filler to see if there was any air pressure building up. There was not, all seems fine. Next i decided to take the oil cap off when the engine was running. There is a lot of noise and considerable air coming out of the where the cap would be (this is the oil cap, not the radiator cap).
Do You Put your hand over the oil fill cap?
Placing your hand over the oil fill cap is not a great way to measure blow-by, and determine an engine’s condition. You and your friends cars have a lot of life left in them, most likely.
