Hi everybody here, I would like to have an idea to try to solve my RX problem, I detect a tiny leak from the right side of my engine, first I though comes from the water pump but after check I noticed comes from a tiny separation begin the water pump and is not from the thermostat housing or any of the hoses there , does some body got an idea of it? please give hand please!!!

 

Hard to see much in the picture.

Is it coming from in between the housing and the end plate?
There are quite a few gaskets there...one between the water pump and front cover and between the front iron and front cover. And at the thermostat. There is a weep hole on the water pump shaft as well that would leak down the side of the block. Could also be a hose or connection....or even the nipple on the radiator under the overflow bottle.....or even the overflow drain
