How to fix oil leaks
What are the different problems that can cause an engine to burn oil in general and the difficulty is expensive to repair each Diagnosing each potential cause.
I found this article that describes some of the problems.
Regarding the diagnosis of the oil consumption and smoke the above article said the following.
With older vehicles that were usually accompanied by a puff of smoke exhaust gas of modern vehicles, the catalytic converter generally prevents the smoke of smoke in the exhaust is vaporized by the converter Unfortunately, this can significantly increase the temperature and damage the converter over time.
In late diagnosis of things, there are some guidelines to follow.
If you see smoke coming from your exhaust, what color is the smoke.
If it is black, it means that you are using too much fuel rich.
If it is white, the car can be burned antifreeze or rare auto trans fluid.
As blue smoke that you see, you can know that oil is the problem can cause smoke What oil.
If the smoke is just starting and disappears quickly, it can be attached and valve or valve guides Indeed, if the car is sitting for long periods of time, the oil has time to seep past the valve seal and collect on top of the valve or if the valve is open, he could run past and above the piston When you start your car, the oil is then burned, which gives it the tell tale breath the cost of blue smoke sET is moderate cost involved in this, according to the vehicle engine If only the joints, this can be accomplished mostly with the motor holding mostly set and replacement joined most of the cost here is the manpower If the valve guides, this requires an engine apart your head will be removed and new guides installed There is much more work here and a little more in some es regions.
If you see smoke you decelerates, it also is a possible sign of valve seals and valve guides or This is because you slow down, there is a great void accumulation in the intake tract is empty enough to get to the oil valve seal if worn cOSTS SET dE as above.
If you see smoke while accelerating, it's a sign your oil control rings are worn down These are the rings used in the ring pack When worn or cylinders are worn past tolerance, oil can circulate beyond the rings as the piston moves down the cylinder the oil control rings normally scrape the oil cylinder, pushing it down into the cost of crank case to fix patch it is quite expensive because it requires a complete reconstruction engine to correct.
If a hematocrit is bad, you normally won t see burning oil What you will see is failure and joints can cause loss of oil and a very dirty engine compartment, is one of those things that can sneak up on you if you aren t pay attention Even if a bad PCV is not a good thing, don t look here for a reason that you are seeing the outgoing oil smoke from the exhaust pipe to fix cOSTS If you catch it before becomes a problem, it is actually fairly cheap to fix just replace the valve if you see leaks at joints or joints, your cost goes well, but it depends on the seal or gasket is an easy escape obtain joints or joints will be a lot less cost, because labor is much less the opposite holds true - work is a factor here.
If you see the blue smoke that disappears after an oil change, but slowly you come closer to your scheduled maintenance, this could be a sign that you have a leak of internal fuel thinning oil as the oil becomes thinner, it goes through the rings easier oil control, causing the vehicle to smoke an easy way to check is by pulling the dipstick and the smell of oil If you smell of fuel, it may be the question that may be caused by an injector which is stuck open, or may be an internal failure of a fuel pressure valve that would allow the gas to escape at the point where it doesn t belong cOSTS secure the diagnosis of what happens will take some money this could be a very low cost solution, at low cost, according to the actual cause.
If you do not see smoke, but you still see lower down the oil time passes, this may be a kind of normal use of oil in your car Take for example my 06 Chevrolet Silverado engine is His an LS variant as these engines get up in age, it is common for them to use more oil you do see the exhaust, but it uses up, not least the engine running and great gas mileage has remained roughly the same.
Your vehicle could also be losing oil by leakage or seepage engines get up mileage This is a very common thing If you see stains on the driveway where you park the car, it could very well be the subject be aware that vehicles will lose more oil during operation as they will just sitting in your driveway.
EDIT In deference to your edit - I can see where a catalytic converter up to temperature can make a difference in the smoke from the pipe of the tail It does not hold, however, to puff of smoke startup blue smoke, like the cat not hot enough to make a difference he also won t make a difference once the catalyst is covered in oil suit or if there is too much oil for the cat to deal with sooner or later, when the oil is burned in this way, you will see the blue smoke you've probably put on new cats at that time, as well.
An engine that burns oil not only oil waste, but can damage the spark plugs, cause ignition misfire and eventually affect the catalytic converter burning oil can also cause more emissions high, resulting in emission tests have failed due to excess production of hydrocarbons.
Over time, the valves wear out the cylinder chambers or valve guides, which hold the on track and create a space in the rooms, this gap allows the oil to enter the combustion chamber, where it burns then once the gap becomes too large, the valve seal can not prevent production of oil in the combustion chamber.
The valve seals prevent the flow of oil in the engine If the valve seals fail or are broken, cracked, worn, or incorrectly installed, the oil will be sucked into the engine cylinders, the compression can not be affected by the oil leak, but the engine will use more oil than necessary.
If the atoms, a byproduct of the motor, built in the ventilation system housing RGC, it can clog the general system, the PCV system acts as an exhaust passage or the breathing of the engine, but the accumulation of pressurized the oil sump This pressure pushes the oil into the engine through the fuel delivery system, and the oil burns.
If the piston rings that seal the combustion chamber of the engine wear, the pressure is returned to the oil sump, thereby creating the same end result when carbon is formed in the PCV rings are installed backwards, twisted on the pistons or not properly staggered, the result will be the same as if they had worn.
-Check Oil Open your car hood and remove the dipstick Wipe dipstick with a clean cloth and insert it back into its tube Pull out the dipstick and check the oil level Add oil until the gauge reads full repeat this every 500 miles If she reads a weak quarter in 500 miles, you have an oil combustion problem.
-Check the exhaust blue smoke from the exhaust pipe of a car while it is running is a sign of the oil burning Smell the exhaust produced higher emissions An engine that is burning This oil also fail to pass an emissions test because of high hydrocarbon emissions.
-Monitor the engine to see if it is misfiring or being rough run an engine that is burning oil will foul the spark plugs, causing it to improperly.
-Inspect the spark plugs pull the spark plug son out a spark plug using a spark plug wrench to remove the spark plug Examine the candle One terminal of spark plug oily, wet or soot is a sign of burning oil Replace the spark plug wire and repeat for each spark plug, working on a spark plug at a time.
Remove the PCV valve with the engine running there should be a strong vacuum pulling the valve If there is no vacuum, the system is clogged with mud and carbon It should be cleaned and replaced valve .
Run the engine at idle for several minutes Run the engine and let it sit for about 15 minutes, restart the engine and immediately increase the engine speed while observing the exhaust If a heavy Bulow bluish smoke is exhausted disappears and the exhaust is relatively clean, the cause is most likely wear excessive valve guide in this case, the valve or valve guide seals guides require a service If the above test the product light smoke and smoke remains at the same level in all conditions of operation, the piston rings must be tested.
Remove the spark plugs and test each cylinder individually for total compression PSI If you find that a cylinder is the low test wet in wet testing the cylinder, remove the dipstick, squirt oil in the cylinder, then testing if the compression in the cylinder occurs, while the cylinder bore piston ring How do we know this because when the oil was thrown into the cylinder, it fills the gap between the rings worn and the cylinder wall, sealing the annulus and thereby increasing the compression in this is the case, consider rebuild or replace the motor.
NOTE Compression Testers are available in most Refer auto parts stores to the manufacturer's instructions for correct use When you do a compression test, it is essential that the ignition system is disabled to prevent booting of motor This is usually done by connecting a wire to each of the spark plug son to a good engine ground away from your work area.
My car usually consumes about 3 liters per 10000 km service interval My car has now 330000 at the counter you didn t specify the type of witch diesel or gasoline engine- In addition, it is important, if the turbine engine First you need to understand the consumption of natural oil for the specific engine.
Here is some information volvo vadis Sound 2 5L engine B5254T with low pressure turbo.
The break-in period oil consumption may be up to 1 liter per 1000 km during a running-in period of about 5000 km if the engine is new or replaced replacement of the piston ring.
Normal driving up 0 25 liters per 1000 km is considered normal oil consumption of high-speed driving with heavy trailers 0 to 40 liters per 1000 km is considered normal oil consumption alpine mountain driving up '0 to 50 liters per 1000 km is considered normal consumption oil the above values for the oil consumption can be used as guidelines if it is suspected that the oil consumption is exceptionally abnormally high.
Note The oil consumption may be as much as the following to 150.000 km The oil consumption may be about 0 35-0 55 liters by 1000 kilometers in all conditions.
To determine the exact consumption of oil a test of at least 1000 km should be performed under controlled conditions oil should be weighed before and after the test drive this way, we can calculate the consumption exact oil.
If the oil overfill has been filled above the maximum recommended level, the oil is forced against the walls of the cylinder and is ejected through the crankcase ventilation The oil level should not be filled above the maximum mark on the dipstick.
Level oil using a non-recommended oil grade Volvo can lead to increased oil consumption of oil contains a greater amount of volatile molecules if the oil is too thin thin oil has trouble maintain a full oil film on the cylinder walls to higher temperatures This results in increased engine wear and increased oil consumption.
Long driving record and continuously conducted at a high speed RPM motor causes high engine temperature thins the oil consumption increases and sharp turns at high engine speed RPM causes oil to be forced against the side of the block -cylindres and against the cylinder walls, which results in a fuel consumption increase.
Mountain driving many long regular engine braking periods also causes high temperature of the engine more oil is drawn into the cylinder due to an increased negative pressure in the intake pipe.
Driving the car idling in city traffic conditions, where the engine may be running for long periods, but only for short distances, does not necessarily mean increased oil consumption, but the report of the oil consumption to the traveled distance can be misleading.
Climate In hot climates, the engine has to work harder at higher temperatures This increases oil consumption.
