This means that the injectors are letting ltoo much fuel in or are leaking after you turn the car off. The petrol is running into the cylinders and past the piston into the oil. This is a very bad thing. It removes the lubrication on the cylinder walls. It dilutes the oil and reduces the lubrication properties. IT can lead to engine failure pretty fast.

SOURCE: oil in a coolant, lots of it got out somehow

Sounds like the usual K-series engine head gasket failure. Needs a new multi layered steel head gasket, steel dowels, engine oil needs flushing and replacing, cooling system needs flushing and new coolant, head needs pressure testing, new through bolts holding engine together needed. Cooling system must be free of airlocks, otherwise it could all happen again.
Find a friendly mechanic you can trust.

Could be a whole gambit of problems

1) Check the HT system is good, contacts clean, good spark on the plugs.
2) Check the water temperature sensor.
3) Check the air filter isn't clogged.

Blueish smoke out of exhust,no power, puddle of oil under car, smells like raw fuel out of exhust


Hi , it sounds like your valve stem oil seals need renewing. If you mix oil with petrol it does not all get ignited hence blue smoke from the oil and the smell of petrol out the exhaust.

I have a 2003 freelander that smells of petrol whilst driving ive heard of this problem before but nwhat is the cause


Hi Paul:
The smell of petrol means that there is unburned fuel somewhere.
That is not good, and could be very bad, especially if it ignited.

I sincerely hope that you are not smelling this inside the vehicle while you are driving it.

Without running through a list of every possibility that I can think of, I'll make some suggestions.
1) When you smell the petrol, immediately pull over and shut the engine off. Lift the hood to access the engine and try to find the leak. Look at hoses, connections, fuel delivery components, gaskets. Look for wet spots, stains, wash marks where petrol may have moved dust and then evaporated.

Patience and a bit of time, and you should find it.

I'm also guessing that this is an external leak since you did not mention lack of power or backfiring.

Another possible is a failed hose connected to the fuel tank, or a faulty tank vent.

It's up to you. You're now detective Sherlock of the Petrol patrol.

Blue smoke after being driven for awhile


if you can then smell the smoke. if it smells of petrol you will need a tune on your car ( getting too much petrol ). if it has no smell or very faint then it could be your head gasket. (water getting to the head causing steam ) worst case would be piston rings expanding through heat and letting oil through ( smell of oil burning ) check oil filler cap and dip stick for white gunk/check exhaust for water dripping out. these are head gasket signs

I have a 1994 toyota estima petrol it smells like a oil burning smell but theres no oil on the ground when i turn it off?


Hi Kiwi, Have a look for oil leaking onto the exhaust system, particularly onto the exhaust manifold. I'm fairly sure that you'll spot something from there. Regards John

I have a 2000 volkswangen jetta vr6 and it has a knocking sound in the top engine need to know if changeing the oil will fix the problem oil look realy thin and smells like gas.


If your oil smells like petrol (gas) this is a big problem. Drain the oil and replace it and the filter. I would take a sample of the oil to a mechanic just to get his opinion. Gas getting into the oil on a modern car (fuel injected) is less common then just burning oil but has been known to happen. Knocking sound is usually crank shaft damage which is not a good prognosis. It is likely if fuel is in there now it will get in there again - Your best chances are to use as heavy weight semi-synthetic oil you can get with the aim that the oil pressure will mean you burn oil in preference to fuel pressure pushing its way into your sump.

I have a gas smell in my oil on my 1995 Mustang GT 5.0. It is milkly


if its a petrol smell then maun suspect is head gasket leaking between a water port and a oil return gallery with the help of a piston hence the petrol as well ,without a complete strip down its impossible to say its between one and two or three and four cylinders or whatever if it was just water in the oil then its highly feasable its a radiator where the oil cooler is in the rad .But this smells of petrol so go the whole hog and pull the heads off

My fiesta 1.6 zetec 16v is blowing blue smoke with strong odour of petrol ,what is wrong with it ?


Hi

it sounds like it is burning oil not petrol but you will smell petrol as the oil is leaking in through the head, the valve stem oil seals will most likely have gone, very common on fords. they are very cheap bt unfortunately you have to remove the cylinder head to replace them so that means a head gasket and a new cambelt and head bolts thats where it gets expensive. in the UK you are looking at about £300 to £500 in a general garage.

there is another solution that will last for months if not years, get some STP the type that you need to heat up to get it to come out of the can, this will seal up the leaking stems and shuld stop the smoke, most people do this before they sell that car.

Valve stem oil seals often go because the car has been driven hard, but you should still expect them to go at around 80-100k miles anyway.

Hope this helps
Regards

Dan
