Oil Leaks Only When Engine Is Hot. by Arizona1: 1:52pm On Mar 03, 2022
I have a Volvo XC90. I noticed that my engine oil is leaking. There's always drops of oil on the ground whenever I park. So I monitored it and noticed that the oil only drops when I drive the car and of course engine will become hot. When I park, after that day, the oil won't drop again. I had to change where I parked to observe this. If the car parks for one week without moving, there won't be any drop of oil on the ground but once the engine is on for at least 30mins, or I drive around for some time, I'll notice a good drop of oil when I park. So I just want to have an idea of where that oil leakage could be coming from before I engage mechanic.

How are you sure it is engine oil? It could be power steering fluid sef because it would only pump when engine is on just a guess.

Get 1 or 2litres of diesel, a brush of small size, on sunday, wear boxers, singlet and eye glasses and devote 2 hours of your time to wash the engine sparkling clean with the diesel and brush.

After cleaning, start vehicle and survey around engine area to know the leaking point. That will tell you what you need to fix or change to stop the oil leak.

Or

Pay a technician to find the leak but ensure he is right to avoid spending or opening engine unnecessarily.

Had any work done in the engine bay recently or around it?And as nurey said,are you very sure it's the engine oil?did you confirm the colour of the liquid on the floor,sometimes it might even be a coolant leak.some coolants have this oily liquid feel to them,you might mistake as clean engine oil leak when dropped.kindly confirm how much the liquid on the floor is after driving and the colour,

Cheers

Bad "crankshaft oil seal" likely the culprit. Located inbtw the engine and transmission. I had similar experience. Engine or transmission will have to be out to fix a new seal.

Thanks boss. Is you car Volvo xc90 as well? I will like to know where you fixed yours or if you have a good reliable volvo mechanic if you're in Lagos. The oil leak is around that timing belt area. I have changed two oil seals when I bought the ride but before I changed those seals, whether the car is hot or cold, oil keeps dropping but now only when I drive it.
