Hello all, new here and having some fun chasing oil leaks on a 2.8jtd in a 2003 Ducato. on the front of the engine there is a fitting that the dipstick tube comes out of, and it would appear it is leaking from this fitting. How is it removed/sealed? To clarify, I can wiggle the fitting about with my hand, so it is not tight in place.

Hello.

On many different vehicles, there is a guide pipe that can be removed where the dipstick

goes. ...but unsure how it is fitted on the 2.8 JTD ! .....

However, oil coming out from there is more likely to be caused by excessive crankcase pressure from blowby.

Check for excessive pressure and the crankcase breather is not blocked.

Assuming the oil is definitely coming out from there...
 
My main oil leak was from the rocker cover gasket which I replaced. Check for a leak in that area.
 
Since I also have a 2.8JTD, I have taken the time to peer underneath would you believe 3 times, in order to examinethe the dipstick fitting as the dipstick entry is hidden by the blowby connection, which branches from the dipstick entry fitting at the crankcase.

Unfortunately the method of attachment is not clear. As there should be no great pressure in the crankcase, I am tempted to speculate that it could be a light push fit with "O" ring{s). It is quite likely that the "O" ring has hardened and perhaps worn with vibration.


I note that on the picture posted by DevonT2001, the adjacent blanking plug seems to have a fibrous jointing material in addition to the copper washer.
Copper washers can be softened and reused, if heated until red hot, and then quenched in water. I have used this trick many times, on sump plug and injector washers, as well as when bending domestic water pipes.

I am attaching the relevant page of the Iveco Daily 2.8JTD manual, which shows the fitting in diagramatic form

Well hey. I got right under my van today, I still have a pesky oil leak also.
Also around the same area as OP. But seems to be coming from higher up also?
The rocker cover gasket has been changed and no leaks from there since.
Just need to determine where the other leaks are coming from now!?
