It is in the narrow area between the cylinder and valve housing as near as I can tell. It's hard to even see in there to figure out exactly where it's coming from let alone to weld in there. JB weld wouldn't hold in that application IMO. The cylinder wall is scored a bit in the area opposite the exhaust valve and one of the score marks is probably a fine crack. 

   I cleaned the engine up last year and ran it to find out where the oil was coming from. This picture was after running for about 5 hours.  I cleaned it up again and ran it for about 1/2 hour and you could see it was coming from that narrow passage between the valve and cylinder sections of the block. Pretty much impossible to get at.

I still dont know what the balance gears are do you see them in my pics? I would scrap em if possible. I hear the are a cause of troubble

Yes, it probably could be sleeved but the engine would also need a rebuild. I'm still looking for another engine and was just talking to someone with a K321 block but it looks like it's the wrong type.

Well it seems I do have them balance gears in my 321. What exactly is the problem with those again?

The bearings give out, letting them make a picture window into the block!

I tried to get the connecting rod off the piston skirts today and what was left of the pston just collapsed in my hands when I tried to get the circlips off. Guess it was pretty weak in a few places.

hum.... I dont think I really NEED a picture window in the block. I wouldnt want the crank to get a cold this winter then call in sick when the first storm hits.  :D

 

Is there anything I need to do when taking them out? or do I just take em off and thats it?

Just take all gears & associated parts (shims & clips) out and you're done.

Unless you want to buy new bearings for them and mike the shafts they run on, take them out.

Yeah, What Daniel said!
