Engine sweat or beginning of an oil leak?

I have a Vauxhall Corsa 2001 which i purchased a month back it has done over 72,000 which isnt really bad for its age- but today i noticed a mark on my drive which looked like a sweat- It was not a puddle, i felt it and it was oil- could this be early signs of an oil leak?





I dont know whether it is because the weather is warm and it maybe sweat , please advise?Engine sweat or beginning of an oil leak?
Engines don't sweat. I wouldn't worry too much but try and ascertain where it is coming from. If it's just an engine oil leak it's not too serious, though it should be investigated as it will probably get worse with time.





But you need to make sure it's not something like power steering or brake fluid which is a bit more serious.Engine sweat or beginning of an oil leak?
probably an oil leak


open the bonnet and look near the left hand front at the top of the engine they should be a sensor with a single wired plug on it this is the oil pressure switch this is usually the culprit.


nearly all the corsa's oil leaks i have seen is from this sensor


expect to pay between 拢30-拢50 maximum for this to be replaced
engines or transmission do not sweat oil, they leak. almost any car will leak a bit with age. First you need to see if it is transmission or engine oil then check your oil levels on a regular basis. If really worried then take to a mechanic to trace source and fix. Me I would not worry about it unless it leaks a lot and the oil levels drop quickly like in a week or two.
You can't do any worse than have a look round the engine/gearbox.





It should be obvious,i.e wet near the leak. It may be something as simple as a rocker gasket or loose oil filter.





Or just tell everyone it's not a leak,it's sweat from all the power it makes........!! ;)
Car engines do not sweat. They leak oil, coolant, brake/clutch fluid, water from air conditioning units but never sweat. Suggest you keep an eye on it, check oil coolant brake/clutch fluid levels. If low top up and monitor loss. If needs be seek Professional advice.
Taste and feel it. If its sweet its coolant, most likely from the radiator top hose, left hand side of radiator. Or if its oil, its likely the sump plug or the gearbox.
lift the bonnet and take off the oil cap where you would put oil in, and see if there is what looks like foam (water and oil mixed) if so there could be a gasket leak, cylinder head etc.
Engines don't sweat like that. See the color of fluid, as different colors mean different leaks.
