Thanks for the help! I guess I will pursue the dye route as everything is pretty clean & dry. I am hoping it is not leaking into combustion chamber or oil pan,
Anyone know whether there is a freeze plug located directly behind/under the passenger side motor mount on a 5.3L 2001 Yukon? And if so, what is the best way to remove & replace w/out removing engine? I have antifreeze on this motor mount & cannot determine a leak source. Any good way to confirm...
