My truck dumped oil today

[KERRSURF]

she's leaking, I think it may be rear of head gasket, she's got oil pressure when topped up and temp is fine.
could it be a feed pipe for turbo or something similar.

from underneath it looks as though oil is appearing from back of engine on passenger side up past bell housing.

The turbo is on the drivers side!

It's probably the rocker cover gasket leaking, they all seem to leak at the back near the bulkhead at some point.

I know the turbos on that side but I wasn't sure if any pipework came from opposite side.

it dumped a fair bit of oil on the mtorway, underside of truck was black!
I stuck in 3.5 lts and limped her home.

someone else suggested crank oil seal, how much to fix this if it turns out to be the problem.

rocker gasket I would tackle myself.
