I've changed the sump gasket on my XE about 3 times now and can't get the bugger to stop leaking.
I'm using a steel sump off an SEH cos it more forgiving when hit by high speed projectiles!! I'm also using the rubber SEH gasket but still the bugger leaks!!!
Any idea as to what I should try, note that I have to take the lump out of the car to get the sump off, else I can move the sump down about 1-2 inch to replace the gasket with the engine in place.
