Putting glow plugs in this thing and found the intake full of oil sludge... looks like the PCV has been dumping it in the intake hose. Is this PCV trouble or blowby death (156K car)? I know my way around farm equipment and if this were a JD it would be turbo or rings time!

Also, there is a fuel leak at the bottom of the inj pump, haven't looked too hard but there seems to be a right angle plastic filter and then a hose into the housing... Is this a o-ring issue or something else. Looks looks like there is a clamp bolt or something right there, haven't messsed with it. Any suggestions/experience here?

Thanks for the help.
