Light smoke/steam is coming from front of engine below handle bars. What do you recommend I look at that could cause this? How do I check the coolant on 95 Honda CB250?

The smoke is coming from the front of the engine below my handlebars; I can't tell if its around or at the area where my exhausts connect. It never did this before and I only drove it around the block and home then noticed the smoke. I had it parked for about a week waiting on my ignition switch (now that is changed this issue is occurring.) I am curious could this be a coolant level issue or i was told check the oil? is there anything else I should check for?

SOURCE: Rough idle, no power, steamy exhaust

The answer was the plug top coils. The plugs and coils were replaced and the car is fine. The steam was not steam - it was white smoke from the catalytic converters.No mayo in the oil and no coolant level drop should have eliminated the head gasket. The steam turned out to be a red herring.

Would guess there is a high liklihood that you splashed some water off of the road onto a hot engine, hot exhaust, etc. Keep an eye on it for a day or two, but if you don't see the steam on a dry day, and your coolant level is stable, relax.

SOURCE: my 325i has been running at low coolant level

Ekun,
What you're describing is a blown head gasket or a cracked head. What's happening is the gasket or head is letting coolant get into the combustion chambers of the engine, producing your white smoke, and accounting for your coolant loss. You need to take it in to get checked out; often times if the head warped or something, it will need to be machined. This is something that's urgent; you can ruin your engine quickly running it this way. For future reference for you, here's the different smokes you will see and what causes them. White smoke-coolant in the combustion chambers, caused by leak in head or head gasket. Blue smoke-oil in combustion chambers, can be caused by worn, broken, or weakened piston rings, faulty PCV valve, worn valve guides. Black smoke-engine running too rich, and unburned fuel is escaping. I hope you get it fixed soon, those 3-series are great cars....mine's been awesome.

Testimonial: "Hey - thanks for coming back so quickly, much appreciated. Spoke to the dealer and an independent yesterday - this is spot on. Thanks"

SOURCE: Oil level low light comes on. When I turn

some cars with oil level warning light on, it doesn't mean that its only reading the engine oil level is low, sometime the transmission fuid too. Did you check your transmission fluid if it is ok or not? try to check and let us know, ok.

What cause white smoke coming out of exhause pipe

White smoke from the tail pipe is moisture/water turned to steam.It comes from the air drawn into the engine and/or coolant in the engine.If you see excessive white smoke and your coolant level is dropping,you are most likely steaming coolant.Oil burning usually comes out as blue smoke.

My car has white smoke coming from the exhaust

he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

Burning smell and tons of smoke coming from tailpipes

White smoke from your tail pipes usually points to water making it into the cylinders. Possibly a bad head gasket or even a cracked block. Gray or black smoke usually points to oil as the culprit.

I was driving home from work my light begin to flash check engine when I got home I noticed that it was smoking I pop the hood and trace where was coming from where the top hose meets the radiator in the...

Your thermostat sits right below that hose and it was probably stuck shut and therefore you overheated the engine.Was there smoke coming out or was it steam?Smoke=bad.Steam=not so bad but it all depends how long it was steaming.Maybe youll need to get the top end of your engine re done.Hopefully not though

Plums of white smoke coming from exhuast when accelerated

Well if you have white smoke when reving up engine then its not smoke its STEAM as you have been lossing coolant by the sound of it (yes) or no,,,,IF yes then you have done a head gasket or something else which
is letting in coolant to the cylinders and when it fires it blowes it out the hot exhaust and causes steam ,, as the only other way to get white smoke could be burning brake fluid/ or kerro.
So does your engine get hot /loosing coolant/missing when running ///any of these will cause your problem.
Let me know how you get on ,, Ron

Engine stalls, check engine light, not fuel filter.

the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.
