Rick Lake...Yes, I still have the Dove dry sump pan. There is no adjustment on the belt...just a gilmer pully to the crank. The surface between the pump section (front of the pan) and the rear section of the pan is a machined aluminum surface. The internal
oil pump is in the stock position and the scavenge pump is on the passenger side and there is a tube running the length of the pan from the scavenge pump.
The reason it leaked is that there is a internal bolt to the block that is hidden inside the front portion of the pan on the passenger side. In order to reach that bolt, you have to slide the rear part of the pan toward the rear, but the bellhousing won't allow enough movement to "slide" it off the scavenge tube.
So, remember, I just started out trying to stop the leak between the front and rear parts of the pan. I thought, just remove the pan, clean everything up, use some good RTV (gray stuff), tighten the pan bolts real good and everything would be good. Not going to happen without pulling the transmission, clutch and bell housing. Not pretty. So, I got it off but it now needs a little work...LOL...but still usable.
Anyway, the system is a good one...uses the stock
oil pump driven off the distributor and a scavenge pump driven off the gilmer pulley. I just decided to go with a new external pump and scavenge system and will probably make a sculpture out of the old one. The Dailey pump, pan and suction manifold is a work of art. I am very pleased. There are some pics of the Dailey pan posted in my profile.
