Hello Jaguar family I drove to work this morning which is a 4-5 minute drive, nothing seemed amiss. Got off work 8.5 hours later, come outside to car see obvious fluid under my car that wasn't there when I arrived. Pulled up slightly, touched the wet spot on ground..oil. Checked the dip stick, there is still oil. My coolant level has dropped slightly but don't feel any leaks on hoses or under header tank.

 

If it's oil it's either engine oil, power steering oil, auto gearbox oil or, if it's towards the rear of the car, differential oil.

You can easily check the level of power steering oil and engine oil but not the other two.

I checked the level of the oil and it the dipstick isnt reading that I lost a massive amount at all. I drove home which is about a 4-5 minute drive, checked under car didn't see any oil. Checked about 15 minutes ago still no oil under the car.

 

I put my finger in the wet spot and it appeared to be engine oil (brown in color)

 

As there's so many components to an engine could be anything, I know when I swapped my engine out it was leaking from the oil pain gasket not saying that's what it is but get it in a lift and you'll be able to check

 

The under-tray usually soaks up all the leaks. If you've got a leak that soaked the insulation to saturation, you may have a serious problem. OR, maybe you don't have the tray anymore?

 

brown?? dirty red?? or the black asphalt being disintegrated by the reaction with the aggressive fluid.
Not seeing in the engine bay is a serious disadvantage. I'm with CeeJay... its probably not oil.

It's a long shot but here's my story. I live in Paradise San Diego California, great weather all year around. Well, a few years ago it got super cold and I didn't leave drive either car, including the Jag. Well it got so cold the seal between the tranny and the pan bagan to leak tranny fluid and I am not talking about Bud-Light! Fortunately, all I had to do was retorque the bolts and problem solved.

Now in your case, maybe you had a few cold nights in Maryland, you only drove 5 minutes, and the tranny seal separated and leaked?

Attached are a few pics of my leak.

Look for oil on each bolt.

Anyone know if this is an original trans pan? (with the big oil drain plug?)

This was the original leak in my garage.

 

Hmm, you’ve given me food for thought. My tranny pan looks the same, so I’ll assume it’s original on my 2007. I had a slight leak over the winter and my pan bolts looked similar. I assumed it was another oil leak and searched high and low, even added some black light leak detection fluid, but never saw anything the rest of this year. I had switched to 0W-40 oil a couple years ago, so switched back to 5W-30 to see how it goes this winter. But maybe it’s just the tranny pan seal, so I’ll have to check the bolts. Thanks for the tip.
