How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Smoke After Warm Up

Oil can enter the combustion chamber past the valve stem seals or pistons rings, so if this symptom persists then one of these components may be compromised. White smoke exiting the exhaust pipe after the engine has warmed is a sign that coolant is burning in the combustion chamber.

White smoke most likely would indicate that water or coolant is getting into the combustion chamber or exhaust port. This can occur if coolant is leaking into the head. It could also be as simple as water entering the exhaust or carburetor after the engine was pressure-washed.
One possible reason for white smoke coming from your car`s exhaust is that the engine is burning oil. This can happen if the oil level in the engine is low or if the oil seal is leaking.
Billowing black smoke is generally a sign that the fuel-air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren`t letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
2 Stroke smoking a lot

When you have a 2 stroke that`s smoking a lot even after being fully warmed up, it`s because there`s too much fuel and not enough air or compression to ignite and burn it off. This could mean your top-end might need a rebuild, or one of the simple factors I list below.

The symptoms of too much car oil

If it is overfilled, the following may occur: Dense white smoke – If you drive your car and see plenty of thick, white exhaust smoke, excess oil may be burning within the engine block, although fluids such as antifreeze may also be the culprit.

White Smoke

It usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket, which can quickly lead to an overheating engine.

Having said that, yes, a thicker motor oil CAN help SLOW DOWN the leaking and smoking.
White Smoke

In extreme cases, you will need to replace your head gasket. At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.

Black exhaust smoke

When your exhaust pipe gives off black smoke, one of the things to get worried about are bad or worn out spark plugs. It means fuel burning in the combustion chamber is not being done 100 percent or burnt fully. It also means that air is not being well mixed with fuel to burn effectively.

White smoke is a result of unburned fuel particles passing through your car`s combustion chamber and out of the exhaust pipe. As previously mentioned, white smoke is related to lower temperatures in the combustion chamber. When the chamber isn`t hot enough, some fuel particles fail to ignite.
Light or thin white exhaust smoke is typically water vapor. You`ll notice it the first time you start your car, especially if it`s a cold day. This happens because condensation naturally collects in the exhaust system.
Step 1 – If you see steam, pull over immediately

If you see any steam coming from your engine, then it`s surely overheating. The steam may not come out in plumes like it does in the movies, but if you see any traces of steam pull over right away.

White smoke from your exhaust almost always indicates a blown head gasket, and just like there is coolant mixed with your engine oil, there will also be engine oil mixed with your coolant.
Excessive Smoke After Warm Up

Blue smoke exiting the exhaust pipe after the engine has warmed may be a sign that gearbox oil is burning in the combustion chamber. While I would never encouraging sniffing your exhaust, combusted gearbox oil will have a different odor than the normal pre-mix oil the engine is using.

A properly jetted two-stroke won`t smoke much under load and after it`s warmed up. They will when cold and warming up, due to the cylinder still being cold and burning off whatever oil or gas was left over from shut down.
Thin, black, fast smoke indicates a well-ventilated fire is nearby. Slow, white, dissipating smoke (first thick but thinning quickly) is a sign of steam, and indicates early stage heating. Brown smoke indicates unfinished wood burning. In lightweight construction, this can be a warning sign for building collapse.
Oil Leaks. Using synthetic oil in the wrong engine can cause gaskets and seals to leak. Oil leaks accumulating under the car and white smoke coming from the exhaust could be signs that you`ve used the wrong oil.
If you notice smoke coming out of the vehicle, do not keep driving. Pull over to the side of the road as soon as you can and shut the engine off. If there`s also low oil pressure, see if you can add some fuel to the car and restart the engine.
white smoke ​Definitions and Synonyms

​noun. DEFINITIONS1. 1. a sign that something has been agreed; from the process of a choosing a new Pope when white smoke coming from a chimney on the Vatican roof shows that one has been chosen. We have finally seen white smoke in the leadership election.

Motor Honey is an oil treatment that you add to your car`s regular motor oil. It`s designed to reduce oil burning (and the smoke that it sometimes causes) without having to make any changes to the engine itself. All you have to do is include one bottle with each oil change.
If you have low engine oil, one of the first signs your car is taking damage from it is when you start to smell smoke. This is caused by friction within the engine`s rods and pistons that aren`t receiving any lubrication. This smoke will smell very oily, almost as though something is burning.
If the engine oil is overfilled by 1 litre or more, the connecting rod and crankshaft will whip oil into it, frothing the engine oil. This causes clogged plugs, rough idling, and engine misfire.

I have a 1996 yamaha wave venture 1100….ran greatsat for 2 yrs..started but only ran for spray into carbs….drained fuel started and ran good. Started about month later and would only run as long as primed with starter fluids…checked fuel filter(ok)…fuel flow to fuel pump ok…output of fuel pump appears ok….but engine will only run as long as starter fluid/gas is sprayed into carbs. I don’t think it’s the carbs as it ran great a month ago…now it’s starving for gas flow….so it appears to be a fuel delivery problem…what would be the sequence of tests up to tearing into the carbs? is there a fuel filter inside the carbs? remember it fires off great when primed…until the fuel spray is consumed…
ANSWER : Check the on/off/reserve valve

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

LX 188. Engine suddenly dies. The fluel in the bowel of the fuel filter is empty. If I crank the engine the filter becomes dry and is collapsing some but the engine does not start. When I remove the supply line from the fuel pump to the carberator and crank the enginge there is a strong stream of gas being pumped out. I tap on the carberator ??? is the float is hung not allowing fuel to enter. Cranking the engine with the line off refills the bowel of the gas filter. Reattache line to the carberator===engine starts. Ran perfect for 20minutes then suddenly died. Repeated all the above and engine again started. What to do to fix this? Thanks
ANSWER : Debrie inside the needle and seat area which has to be cleaned out with carburetor cleaner and compressed air

My polaris (Sportsman 700 2002) consumes about 1 litre of oil for every 200 miles. I replace the oil dipstick tube going into the engine,, because ther was a crack at the base, but it wasn’t the only problem obviously. The thing is, that normally when an engine burns oil, you can see smoke in the eshast fumes, but there doen’t seem to be any smoke. everything else goes fine. What’s the next step, because I live in Kuujjuaq situated in the Nunavik(Tip of norhern Québec) and ther are no qualified mehanics in this town, so I need some to guide me to the next step…
ANSWER : I had that problem some time ago and could not find any leak or there was no smoke. What we found was when I put the car up on the hoist there was a leak under neath the engine. Not enough to run out but when the car was driven it would throw the oil out underneath the car. I forget what one but I think the oil drain gasket was leaking. just enough leak to make the oil disappear. Put it on the hoist and see if your engine area is wet with oil.and pin point the area.
Hope this helps
