oil leak

[mjurecki]

i've been having a small oil leak when its below 40 when it first starts and about 5 min after it starts and warms up it stops leaking oil. i found the oil leak but i don't exactly know what the part is or if i can just replace a seal or the whole part

its a 2000 f350 4x4 that pic is not the actual engine i was looking on ebay and just happened to see that it had to the same part that mine did. as long as i keep the truck plugged in 24hr it won't leak but if i leave it unplugged and it gets real cold and i try to start it it will leak a good 1/4 qt out.

The picture you show is the oil cooler and it has replaceable orings for seals
