Looking further, it seemed it was coming from the RH engine mount.
I pulled it out after removing the lower T30? bolt on the bottom and the 15 mm nut on top. I had to jack up the engine 1-2" but it came out.

Got a replacement from my local Jag dealer as many seemed to report that the aftermarket URO shock mounts even though it was twice the price $130 vs $68.

Only took about 40 mins out and in for the left hand side. The right looks harder, but I guess the left take a lot of the load under acceleration.
