[Mgs] Oil leak ( stream! ) problem

[Ed's Shop]

<<Based on your description, my first guess would be the rubber seal on the oil filter mount. It's a part that people probably seldom replace but would eventually deteriorate.

See parts 73 and/or 78 on this Moss diagram:

Agreed, David.  AND the bolt's washer (#75) but that, most likely, 
wouldn't give out the amount of oil he described<G>!!  But if it was leaking, would be a PITA to find<VBG>!!
