Sorry for the ignorant question: What does"under washer" mean? My 59 has a 261. I was going to change the oil prior to trying to fire it for the first time, and then again after. The first fire. Unfortuntaly, the dipstick at some point lost the cap, and someone just ran some bailing wire through a hole to keep it from sliding down into the motor. I did a google search for oil capacity, and am seeing different numbers, although I am feeling pretty safe putting in 5 quarts just to start it. Thanks, on a side note, where is a good place to buy the right dipstick?
