i took  it apart and found lots of oil showing on all 6

else looked ok. 


Tim,
It would be interesting to find out more about this problem. If you are  also 
interested, please remove the rings on one or more pistons and
1) check the clearance of the pistons in their cylinders.
2) check several rings in their cylinders for the amount of ring gap and  
also for whether there might be any incorrect contact with the wall. (Put ring  
in cyl and look for light showing between ring and cyl)
3) What kind of wall surfaces are there? Are the honing cross-cuts still  
there? Are there any grooves or scores on the walls?
4) What rod bearing clearances do you find? (question: could there possibly  
be 10 u/s bearings on std journals?)
 
Please let us know what you find.
 
Thanks,
Regards,
Bob Helt
