What is this engine part? Pics included

So I finally got all my little odds and ends on the truck fixed up (lights, reverse alarm, tranny fluid, fuel leak, etc..) and I notice another oil leak. It drips onto the filter and I thought that was the problem but I replaced the filter and cleaned the housing.

I ran the truck while looking under for leaks and found the oil coming from the center of this large (2.5"+/-) pipe that goes from above the oil filter housing to the front of the engine on the drivers side, just below the exhaust manifold. I have no idea what this part is but it seems to be part of the oil system. I assume it transfers the oil to or from the engine and through the filter but have no clue.

Here are some pictures from another engine where I circled or pointed to it in green.




Thanks for any help, it's greatly appreciated,

-Derek

Well, I yanked the whole thing out and can't see where the leak is coming from. I hope I can just replace the O-rings and solve the problem but since it's out I might as well replace the housing and never worry about it again.

Apparently, it's the oil heater (according to my Haynes manual) which explains the coolant running through it too.

it's kinda both a heater and a cooler, it's function is to keep the engine oil at an optimum temp to operate the injectors correctly.

Called Ford today to get a price on a new oil filter housing with that leaking pipe and they told me it would be over $1000 and would have to be ordered from Canada.

For a 94 with only 55,000 miles, this d*mn diesel has given me more trouble than my 92 Ram diesel with 276,000 miles . You just can't beat a Cummins...

Take it off and change the o-rings. Ford should have all the gasket kits in stock, probably $20 for the o-rings, $15-$20 for the 2 gaskets that seal it to the block. When reassembling, make sure to oil the o-rings and we use our shop press to put the ends back on.

Yeah I replaced all the O rings and the little gaskets for where the unit bolts to the block. After 6 hours of removal and installation, I ran the truck and as soon as it built oil pressure, the oil started squirting from a few pinholes in the side of the tube.

I found an assembly on Ebay for $50, so when that gets here I will try that. It better work, it's not easy taking it all apart.
