 I have an oil leak coming from my distributor body. it is dripping out of the  vent holes in the lower surface of the main body. I do not have any leaks coming from the housing bolted to the block. I also replaced the o-ring on the distributor neck and have verified no leaks. Pulled the unit and the LOWER seal at the driven gear is very loose/worn.

 Looking for a source to buy a new seal, but all I have seen so far is a full Bosch rebuild

kit (pn 1237010007).

 

Any comments/advice on replacing just that lower seal?

BTW... this is an electronic ignition dist from an E21. Runs real well, but the oil drips right onto the header :(

If you are shoving oil up the distributor shaft I suspect a clogged drain hole in the distributor mount housing. If someone used sealant on the gasket it is very easy to plug up the drain back hole. Oil gets into the housing from the rear cam bearing to help lubricate the distributor gears but it needs to drain back into the head freely. If it is not able to flow back it will be pushed up the dist shaft.

mine did this for a bit right after a rebuild, stopped after a few thousand kms (not sure if it was just because the rings hadn't fully seated, or if it was the small hole in the flange/gasket, as i replaced it twice after the rebuild).  i was chasing oil leaks in this area for a while too, with  the flange gasket and the O ring.

I did not use any sealant when reassembling the the dist housing to block. Just a new gasket. Just to be sure of no blockage, is there a way to fish a wire down the housing with dist out?

OK, just ran out to the shop and checked. there was oil about 1/3 way up the housing shaft "well". Fished a wire and found the hole, Felt semi-open, but did get a couple small pieces of gasket material out of it.  Maybe it was partially blocked.Oil drains quiclky now.

 THANKS Preyupy, hope that solves it. Will reinstall the distributor tomorrow. Took it apart some tonight for a good cleaning. Will look through forums for end play info, but any comments are helpfull there too.
