slight oil leak cyl base

[kodioneill]

1974 911 2.7 rebuilt engine from bottom up with no issues except one. the center cylinder base right side seems to seep oil where it washes down the side of the block. not sure if it is coming from the top or sides but it only leaks when running and not a lot. going to pull engine next week to clean up body in this area. used new base gaskets had walt from comp eng fly cut the spigots can't seem to figure out what happend here!

it could possibly be coming from above, like the breather area. leaks from up there usually show up around #6 cylinder, but you never know. check it out with a mirror and flashlight.
