This might be a dumb thought, but you said its an auto oiler that has been disconnected - I wonder if they disconnected everything including the low oil alarm? *

Usually there are different beeping patterns for overheat and low oil. *Find out which is which and go from there. *

Can you put you hand on the block without burning it after a few minutes?

I had a friend that burned up a 150 force. It had a good stream of water, but alarm started going off and he didn't know any better. The water coming from the pisser was hooooot and he kept gettin it till she died.

Good luck! *Nice pics - is that your service weapon *8) ;D

P.S. I know nothing about Mercs - never owned one so this is all hearsay, your honor.
