I have a 97 model Discovery and have a strange oil leak that no-one can find. At idle there is no sign of oil leak. After a 5km drive there is oil everywhere under the car, looks like it is starting at the front of the engine and blowing to the back as the car drives. My mechanic has just about given up on it. Anyone have any suggestions on what might be causing this? It has had a new sump gasket and it isnt leaking here. Will appreciate any help on this one. Cheers Col

What engine ?
If you could give us details of engine, car, year, model might be helpful. I am thinking back pressure via a breather. Although, I suppose it could very easily be one of several oil seals or gaskets.

P.S. How much oil in reality is coming out? A little oil goes a long way, how much dipstick drop is present. Otherwise, excellent for anti-rusting.
"9 out of 10 drivers are idiots, pray you don't meet the other 8."
Is it engine oil, EP90 axle oil or gearbox oil? Any halfwit mechanic should be able to tell the difference. If it starts very much at the front and is not axle oil then consider an oil cooler leak which might only happen when a thermostat in the system allows flow due to hot oil. A matrix leak would wet the radiators but a hose leak might not. Finding it should not be a problem if logic is used to follow through possible scenarios using the evidence as presented.

I was not watching the adverts on TV and thinking the oil cooler sounded likely .Pop off the grille and check for contamination if its oily you have your source - a good radiator repair specialist should be able to sort it for you. Derek
The engine is a petrol V8. Thanks to all of you so far who have responded, I am getting the mechanic to check it out. Col
Get him to check the front crank seal too....oddly it will be clean (as the oil washes it nicely!)
Blocked engine breather causing over pressure & one of the crank seal will go first?? That's what happened to mine!!

If its leaking that far forward you may have sprung a leak in one of the oil cooler lines. The lines run from the oil filter to the front of the radiator. Good luck.
