The engine on this bike is a 2-cycle motor. What that means is, it must be fueled with a gas/2-cycle oil mixture. Oil in the exhaust (depending on the amount and type of oil) is not a clear indication anything is wrong with the bike.

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.

95 camaro oil leak causing smoke


You need to determine if it is your oil pan, oil sender switch, oil filter, etc. dripping oil onto your exhaust causing the smoke, or if it is coming out of the exhaust itself. If it is dripping onto the exhaust, deal with sealing the affected area. (new oil pan gasket, sender switch, etc.) If coming out of the exhaust, indicated worn piston rings or valve seals.

Why would oil come out exhaust pipe?


Either you may have over filled the oil or possibly you having problems with the exhaust gas blow by. A build up of fluid can cause the inlet system to pressurise and this forces oil vapor in to the inlet system and out through the exhaust.

Blue smoke from my cherokee at 210 degrees


Hi there:
I suspect it is a exhaust valve guide problem. When an exhaust guide is loose in the engine or leaking oil, the oil never enters the combustion chamber. Oil drops through the guide and into the exhaust port of the head. The exhaust stream then carries the unburnded oil out to the exhaust. As the exhaust system warms up, the oil then burns off and leaves as blue smoke.

Remove the valve cover and take a flashlight and closely look at all the valve seals and guides, especially the exhaust guides and seals.

Backfires badly when downshifting or just letting off the throttle v-star 1100


Most people have this problem after changing the exhaust system. In your case you have to unbolt the exhaust system just to change the oil filter during an oil change. There is an oil filter relocation kit available for around $400 that allows you to both use a spin on filter and not have to unbolt the exhaust system every time you change the oil. The cause of your problem is air leaking past the exhaust o-rings in the head. Buy new exhaust o-ring gaskets for the head and your problem should be solved. If there is a sealing pipe gasket going from the head pipe to the muffler you may have to replace that too. The cause of your problem was probably an oil change where the mechanic replaced the oil filter but did not bother to replace the exhaust o-ring gaskets. Happy riding.

Exhaust leak and oil loss


the valve seals leaking oil inside the cylinder will cause an internal oil leak you can't see. exhaust leak is something different. best of luck.

Oil loss on the exhaust anteriorly


The last time I saw a Buell with Oil on the exhaust it was because the oil filter was seeping oil around the seal where it was not tight enough. I was able to tighten it by hand and wipe off the oil with a paper towel and the oil appearing on the exhaust went away.
