    thanks for your quick response,i found a local mechanic who has experience with this problem i don't believe the car was ever overheated but, i don't know for sure. the engine sounds fine and runs ok it has averaged around 28 mi per gallon not great but i guess it is exceptable ihave kept a close eye on the coolant level and temp gauge it hasn't given any sign of losing coolant just the oil issue

First, you need to figure out what caused the problem in the first place, because just replacing parts won't prevent the problem from returning later. Do you know which of the two heads is the problem? Buy a Haynes manual from a local auto parts store and get busy!!! There is probably a lot of room under the hood of your Forester to work with. Start with a good shampooing of the engine compartment at a do-it-yourself car wash. Has your engine ever been overheated?? Usually an overheat will cause a head gasket to go bad because of a faulty fan switch or temp sensor. There is a product at most of the large chain auto parts stores that can reseal a leaking head gasket without removing the head. You should be using only Subaru anti-freeze in this car, as the regular "green" stuff used in most American cars is too caustic to aluminum parts and may be the cause of your leaking head gasket. I've seen Japanese heads that look like Swiss cheese because the owner used improper coolant. I wouldn't change the head gasket unless you were totally sure that nothing else would help, but you can do it yourself if you are determined enough but you are going to have to pull the engine to get the head gasket replaced and you should just change both since you will have it out anyway. The reason it is such a pain to and you have to do this is because it is a boxer engine and the heads are up almost against the wheel wells. Again, the haynes manual will save you if you decide to do this as it will have full instructions with pictures on how to do this. You are going to need a lot of tools that you probably don't have that could run you up to $1000, so it is your choice how you want to proceed. A Subaru properly maintained should last for 250,000 miles or more, with proper attention but then again this car is known to have its problems. Let me know how this turns out.

I have a 2005 dodge neon srt 4, 2.4 L, turbo.I have blue smoke coming from the exhaust and oil on the block.It is losing an excessive amount of oil.


Blue smoke indicates that your engine is burning oil and at for your leak. Might want to perform a complete engine cleaning with a steam cleaner and determine where the oil leak is coming from.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

What makes a 2008 tribeca lose excessive amounts of oil


Newer cars with catalytic converters will burn oil/smoke that is leaking, so bad piston rings/valves will not show blue smoke.

Blue smoke coming from exhaust


Blue smoke coming out of the exhaust indicates that oil is getting into the piston cylinder and being burned along with the gas. This could be a leaking head gasket, worn piston rings, or the wrong weight engine oil (viscosity too low). A leak down test will be needed to diagnose.
Have you checked your engine oil level?

Smoke from the exhaust at start up means that the valve seals are leaking oil into the cylinder, smoke when you accellerate means that the piston rings are leaking oil.

Engine smoke and smell


You have a bad head gasket. So far the leak is not so bad but will eventually reach the oiling openings in the gasket so watch out for that. Change them as soon as you can

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

97 cavalier - blue smoke and new clicking sound


Hi. these symptoms are leading me to believe that you are having some serious ware that is located in the cylinder region due to the deprecating factor of the piston rings. The blue smoke is evidence of massive oil consumption due to the passage of oil into the piston chamber. the bad rings will let the oil in the combustion chamber and it will burn at an accelerated rate in this manner. You are also having valve issues as well. the seals are bad and the valve timing is off as well. This Will only get worse and you will continue to lose engine compression as well. i would schedule check up at the local mechanic shop soon. the engine will die soon. its due for a complete rebuild.

Please rate and god bless:)
