Ok I just replaced my head Gasket on my 94 4Runner 3L V6 and it seems to have fuel in the coolant.....But the coolant level is not getting any fuller??? Is it possible the fuel was in the block from before when the gasket went??? Or could I have swaped two of the lines fuel/coolant off the intake....? What can I do to isolate the problem & does anyone have a picture of the location of the Lines off the manifold rhs.....???
