Water leak, or split driver side engine mount would be my guess...
Cheers.
I'm leaning toward the engine mount issue as when I poked the circle part it was soft and felt like and it wasn't holding on properly
Oh cool! Engine mount goo
Yes, its engine mount goo, mine went a few months ago, and its a bugger to clean off, more than likely its just the fluid sack that has ruptured and the rubber will be OK.
Still a reason to change I'd say :-)
Have u changed urs yet mate? I just ordered the street unit one
