Re: DD 6V92 Reply #25 – December 29, 2015, 07:54:25 am Ok the pump is installed test driven and triple checked for leaks. However, When I returned back to the storage area and checked everything for the third go around I noticed a small amount of oil seeping out of this mysterious hole in the side of the pump see attached. I looked at the old pump and that hole is not there. I called DD in Tampa spoke to the service dept and was told that hole was part of the molding of the pump. That can't be right. I decided to double check the mounting bolts on the pump they were very very tight but was able to tighten 1/8 of a turn and it has seemed to have stopped. Any thoughts?ThanksWoodie Quote Selected

Any thoughts?That appears to be a "weep" hole which would leak water when the seal went bad instead of dumping it into the crankcase. I am not a DD specialist but have seen such holes on many other engine water pumps. As to why it would have leaked oil I cannot guess. Could it have been leaking at the gasket or what ever seal it uses to keep the oil in and dripping down to that hole?ThanksWoodie Quote Selected
Re: DD 6V92 Reply #27 – December 29, 2015, 11:34:06 am Just an idea so it looks nice,paint that shiney new pump or in a couple of weeks it will be rusty,will not make it last anylonger just look neater.You do not have to use hi heat paint on that pump,krylon is good. Quote Selected
Re: DD 6V92 Reply #29 – December 29, 2015, 06:49:12 pm Woodie,I don't think it's in a location that would work for a weep hole. I do think it's a casing artifact. The entire case behind the water pump is an oil bath so any location not perfectly sealed can leak. Hopefully you fixed it by tightening the bolt. If not I would suspect that maybe you didn't get the giant o-ring on the back properly seated. It would be a pain in the butt to pull the pump and check but if it keeps leaking you may have to go that route. Be sure to NOT strip out the threads on that aluminum case or you will be pulling the pump anyway!Including pics of mine. As you can see it's already rusting even with painting. Paint sooner rather than later. Seems I have a new item on my todo...see yaken Quote Selected
Re: DD 6V92 Reply #30 – December 29, 2015, 08:59:45 pm Boy Ken, that looks terrible. I would replace the pump if I were you. You seem to like playing with the cooling system so much, why not?By the way, Ken and I are good friends and he understands my dry humor. Quote Selected 1 Likes

Re: DD 6V92 Reply #32 – December 29, 2015, 10:26:00 pm If the rubber gasket had slipped wouldn't it be leaking where the pump meets the aluminum housing? We just stopped for the night on the way to the keys. I just looked at the pump and it is indeed seeping oil and slinging it a bit. Ugh the last thing I want to do is take that pump off again. Maybe a defective pump? BTW the temp is running from about 190-200 pulling my jeep about 62mph. You can tell when the fan comes on the temp drops very quickly.Woodie Quote Selected
Re: DD 6V92 Reply #33 – December 29, 2015, 10:31:03 pm What about sealing up the hole? According to DD it's not pressurized oil in that area it is fed in and slings around with the gears.Woodie Quote Selected

Just never let it get over 210 for any length of time. Quote Selected
