99 front cover coolant leak

been awhile since I been here . I have a 99 350 SD it has
a cold water leak that is very slight probally one drop a minute
when I have the sytem pressrized to 16 psi and it's totally cold .
Otherwise it maybe a couple drops under truck after it's been setting
a day or two . Thought intially it was the water pump but after looking at it closely I think the upper part of the front cover is whats leaking .
When I warm motor up it stops , I have 388,000 on this motor and wonder can cover be resealed without removing engine ? I really hate the thought of pulling the motor for such a small leak

Mcgoo,

Have been experiencing the same thing exactly. This condition recently began since our weather temperatures have been 20 degrees f at night. I have installed a new water pump 35,000 mile ago along with thermostat, new hoses and clamps. The engine now has 168,000 on it. I believe that I see a light bit of water comming from the top of the water pump to front cover area, very difficult to diagnose.
Have added a bottle of water pump lube, hoping that it was a the O-Ring between the water pump/ fornt cover shrinking during the cold temps and that the lube would help this condition. I really do not want to tear into to this again, so for now, going to keep an eye on this.

Has any one experienced this?????? and know what this may be????

John

When it's cold outside my truck drips a bit of coolant also. My truck drips from the metal pipe that attaches the lower radiator hose to the pump. The drip comes from that pipe where it hooks to the pump.

you can get a rubber gasket at autoparts store i have done that 2 times for different trucks and it worked. The other way is to buy a whole new pump. take off the lower pipe on water pump and seal it with a new rubber ring and seal it with gasket sealer so as to not have to worry about it ever again
