Lehman oil leak

Hi All,

Here is my main oil leak. I can find nothing in the shop manual about what this is.
The large six sided "nut" if you will, spins... on all 6 cylinders. I'm guessing it's a seal perhaps?

Its the seal around the intake pipe for the injector(s) and they just need to be given a little love with a wrench. None should "spin."

While you are at it, take a close look at the mount for the lift pump, they are famous for leaking oil and the oil always migrates somewhere that isn't leaking and will annoy you trying to solve it.

There are newer, better seals for there if tightening doesn't work.
