I have been a member of this forum for sometime now and have posted a couple of time usually seeking mechanical advice so here I go again. My old Merc 1626 has developed a water leak between the cylinder heads it has been doing it for awhile now it, doesn't seem to increase when the engine is running it just drips away at a similar rate going or stopped about a litre an hour when you are driving. The truck runs very cool so I expect it doesn't build up much pressure in the cooling system when it is running. When the tuck is left standing for a week or so the water drips out until the water levels evens out.
I have cleaned the offending area and can see the water running down between the heads but can't see where it is coming from, there is a welch plug in the side of the head but it doesn't seem to be coming from it , so this only leaves the head gasket. It doesn't look like a huge job to pull the head off but does anyone think it is worth trying chemiweld or a similar product before pulling the head or heads off because I am can't see exactly which head is leaking..
thanks
