I was surprised that those inserts failed so quickly...the engines were rebuilt shortly before they left, so they should of had less than 10,000 miles on them, and it appeared they were careful to frequently change oil. Any thoughts on that? They have sure had their share of problems....one of the cars broke an axle, and they appeared to have gotten several tanks of dirty gas. I was also surprised that they started that long trip with what appears to have been an original fan blade. It caused a lot of damage when it let loose. I keep thinking that the word has been out there for quite a while on those, but some folks keep thinking that somehow their's will be just fine......but the blog and photos are outstanding....one of the wives is responsible for that and it is very well done and interesting reading.
