I've had a couple of "close scrapes" and felt that fitting a Wolf Sump Protector would be good insurance.
When we got the car up on a lift it became clear just how much damage there was.
This photo shows the oil filter housing. I'm told that if the hex end is scraped off all the oil comes out.... So at the next service a new filter housing will be fitted!
From the front the damage was mostly superficial, but covered a wide area. The oil drain plug had lost about 2mm from one side. Again, a new one will be fitted at the next service.
Here is the guard, fitted (with a lot of help from Tom).
I don't really understand why MMC didn't fit a guard, there are unused attachment points in the front cross member and the chassis tub behind the engine.
