Worst case, if only you were around here, there are four 617 motors at the local junkyard in cars... a 123, two 116s, and a 126.

They were $40 + $35 core last week.
This makes me think that I really need to change those oil cooler lines here ASAP, I wasn't aware they were that vital. Sure oil runs through them but I didn't know they were under all the pressure.
