Too much fuel being put in the engine and it gets by the rings and if it has a mechanical pump attached to the motor, it can be leaking inside and running into the crankcase. Too much and the oil will be so thin that it no longer lubricates and you loose a bearing.
I doubt that Linseed Oil is generally described as noxious. It does not hurt, injure or corrupt. Many would consider the odour to be pleasant
An indication of overheating of some sort. Could be caused by a number of things. Clutch slipping, whether from normal wear and tear or from driver riding the clutch. Also, could be caused by the transmission being tasked beyond it's limits, like towing or carrying a load heavier than the vehicle is rated for.
No. The exhaust manifold only carries burned exhaust fumes from the engine to the rear of the vehicle. It has nothing to do with the oil or fuel system. It also cannot prevent the engine from starting. However a clogged catalytic converter can cause the engine not to start. Fuel in the oil is caused by a leaking injector on a FI engine or a bad needle valve and seat of an carburetor engine.
For one thing, you will smell it. It smells kinda' like tar. You will also have smoke coming out of the exhaust pipe. Your spark plugs will also look kinda' black from burning oil because the oil is probably being burned with fuel. I'm not sure about this part, but I think that oil is probably getting into the pistons of the engine. That would mean you have a leak somewhere. I think this can usually be fixed by replacing the gaskets. Call an automotive store for more specific information.
Cylinder misfire, somthing causing too much fuel to be injected, such as a bad sensor. Check engine light should be on with this condition, unleass you had a recent no start problem that would keep adding fuel while your cranking.
if the oil smells like gs, this means that your fuel system ,usually the carburettor, is leaking fuel into the block,take it to a mechanic
sounds like a bad head gasket possibly
gas smell in oil is caused by blow by raw fuel pasing the rings on the piston therefore getting in the oil...........bad rings Now, now... That's not very fair. Just because there's a gasoline smell in the oil doesn't mean you should go tearing your engine apart to get to the rings. Generally this problem is caused by a vehicle running way too rich (is it misfiring?) or is a problem in the fuel pump area. Don't force a rebuild just because you smell gas in the oil. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info
Smell the oil, if smells like some gas is in it. then it would be ur fuel pressure regulator.
The gas will be darker and have a different smell
Remove the oil dipstick and smell to see if there is fuel odor. If you smell fuel, then check the spark plug for a good spark, or the carburetor adjustments for correct mixture. Sounds like unburnt fuel is seeping through the cylinder wall into the crankcase, elevating the level of the oil.
Knowing what year, make and model you have would help but, excess gasoline is getting into the engine oil, could be from a faulty fuel injector, fuel pressure regulator or in the older vehicles, a flooding carburetor or faulty fuel pump.
Yes anti freeze has a sweet smell, at least in comparison to the normal fuel and oil smells of a car
Not knowing what vehicle and engine you have you may have a faulty fuel pump leaking gasoline into the engine crankcase.
Diesel fuel smells the same as home heating oil.
don't poop so much fanny breath :)
Aromatics, or more commonly termed Volatiles, in fuel oil are substances in the oil that will completely evaporate at 270 degrees F (132C). These are what give oil it's characteristic smell (aroma).
