It's ironic that you asked that today, just yesterday I was checking out my LA .65 I converted to Diesel and I don't think there is enough room for a second washer on the front. What called my attention to it was the fact that on deceleration I was getting that rattling noise that some engines make at part throttle or when slowing. caused by the crankshaft pistoning in and out. I do not see how it can make that noise when there is so little room for the crankshaft to move in and out.
