although are close to a rebuild anyways...
good luck pal!
I missed the 20-50 part. I definatley wouldn't run 20-50 in it. You are going to do more harm than good with that thick of oil. If it is your rod bearings you will actually ruin them faster with the 20-50 because on intitial start up it doesn't flow well. I wouldn't run anything thicker than 10-40 and if it uses that much oil then it is time to rbuild or replace the entire engine.
