Unhappy Vacuum Pump Rebuild?

Okay - Oil is dripping on my feet...and oil is also dripping out of my airfilter box.
How bad are we talking here?
The oil on my feet is coming from the ignition vacuum line...I'm assuming the diaphragm in the pump is leaking.
Are these leaks related?
How hard to rebuild the pump and what parts do I need? I looked at the DIY but the link is old.

There is extensive information in the archives.... which can be accessed by using the search box... pictures are there also....
Are you sure the oil at your feet is not from the oil line to the back of your oil pressure guage ? That is more common... could happen at the same time...

I just replaced the diaphragm in the vacuum pump in my '80 300 TD last week. Do you have symptoms of vacuum failure such as no brake boost, no door locking, no engine shutoff, weird shifting of auto trans, along with oil in the air filter? I had these and they were all fixed by a new diaphragm. The old one had a hole about 1/8 by 3/8 inch. The 2 check valves under the small cover seemed all right; I just cleaned and replaced them.
I removed the radiator and loosened the fan and was able to remove the 8 slot-head screws on the front of the pump to get at the diaphragm which was secured by a 5mm allen screw. Also disconnected the 2 vacuum lines from the pump. Looking back at it now I think it might be possible to do this without removing the radiator, with the use of stubby tools. A lot easier with the radiator and fan shroud out of the way, though.
Diaphragm kit from Fastlane $23 or so with shipping, arrived one day after ordered. See my post "Blue stuff in vac repair kit."

There are two styles of pumps... you need to find out which you have before ordering parts... all that is in the archives... with pictures and parts numbers.. and , yes, it can be done without removing the radiator on a 240... I have pictures to prove that... and think I have posted them....

Thanks...I'll search the archives. Positive the leak is from the Ignition vacuum line. Pulled it off and oil dripped out of it...as well as some lines from the firewall.
Glad to hear I don't have to pull the radiator.
