I am battling an intermittent leak. It shows up on the crossover pipe, sometimes when it is cold, sometimes when it is hot. It seems to be following the transmission cooler lines and the cable from the battery to the starter.
it seems to be coming from the right side of the block. The motor mount is in the way to see the leak or the trail of the leak.. I can see my block heater and one other freeze plug and they are dry. I thought it may be a hose that only leaks when heated or cooled, but does not seem to be from the hoses. The water pump and weep hole are dry.
The only thing I can't completely see is the thermostat housing. Are there any other possible places to look on the right side of the block?
