lol more than likely we're talking bout the same thing
and good plan walkin in with the diagram hehe
k here's all possible water leaks on that side of the engine
- gasket which thermostat rear housing bolts to on the head
- block off plate on turbo (no pipes go to this one)
- water lines to the turbo from thermostat housing
- main water union located in center rear of head
- top of 90 degree hose going to main water union
- hose clamp closest to bottom of thermostat coming from turbo water lines
- banjo bolt that bolts into the lower rear of thermostat housing
- bottom of 90 degree hose going to main water union connecting to main water pipe
- flange/gasket bolts directly to back of water pump/front timing cover connects main water pipe to thermostat
- 90 degree hose that always blows out and takes agessssss to even get to located behind thermostat connecting to main water pipe
- other side of 90 degree pipe connecting to bottom of thermostat
- lower radiator pipe connecting to front plate/timing cover
if you need anything explained more in detail i'll be happy to help out
