Undertray pad replacement
 

I had a "significient" oil leak last year (2010 XKR) , and only recently got around to some further investigation as to where all the oil went. Besides leaking out of the undertray pan, upon removal of the plastic undertray I found the liner pad saturated with oil. I removed the pad as it was held down by some gussets, and called my local jag dealer. Of course there is no listing for a simple pad replacement. Only the entire undertray is listed available --for $1132! So, I cleaned up the undertray and reinstalled it without the pad.
My question then is, does this pad have some other function than catching a few drops of oil on occasion? Do I even need it? I'm considering finding some other source of a similar material and sort of making my own replacement, but am thinking that it is just a convenience and not an essential component,
Anyone ever replace the pan or even look at this pad?

Pretty sure my ‘07 XK doesn’t have a pad on the undertray. Guess it doesn’t have a problem with incontinence. :D

My opinion, it's there to do what yours did and that's keep the oil off the ground. It's possible that it serves some slight sound barrier function but I doubt it.

Just an FYI if you're looking to source a replacement, a neighbor of mine has an Ford F150 with a funky catch can that left oil on his floor after an oil change @ jiffylube. They gave him some oil absorption pads to lay on his floor. I'm guessing they'd sell you a few and you could fasten them to the under tray in the same fashion as the OEM. You can get them on Amazon:

Hope the leak is fixed.

Be very careful with fire risk.
Make sure you use a material that wont ignite, if it touches the exhaust in the case of an accident.
You also dont want anything that will absorb water and hold on to it.

Well that would suck, wouldn't it?

Thanks for the link Sean. These should probably work. Leak was from the oil filter. When I replaced it, I must have ripped the gasket somehow and didn't tighten the filter enough. Oddly it didn't leak right away, so I thought that I was ok. --But this is last years incident. Seems no worse for the leak.

Yep, my bad. Something like this is probably as close to OEM as you'll get - flame resistant and won't absorb water.
