The dipstick on my 2.5 TD leaks.  When I say leaks, normal running it is fine, but if I jack the car up from the drivers side, oil escapes from the joint between the dipstick tube and the sump.

Is there meant to be some sort of seal or o-ring in the hole that the dipstick tube slots into?  Because if there is, mine is worn out or missing.  If there is one, does anyone have a part number?  I'm surprised it doesn't leak when the engine is running, as surely the oil pressure would force it out?

Is that the one I sent you Craig?
I can honestly say it was certainly holding the oil in my old engine, cos when I pulled it out, the oil came out as well! Luckily it was onto a gravel and leaf strewn hard standing.
I did check the bottom 'O' ring and it did appear to be in good nick.

There is an O ring.

There is an O ring.

Do you know if the o- ring is on the bottom of the tube, or set into the hole it slots into?

Crikes, you're reliant on my memory from 7 or 8yrs ago

I have a feeling it pushes on the dipstick, up against a ridge.  But nothing, I suppose, to stop it coming off and sitting on a similar ridge in the top of the sump
