Problems w/6.0, 6.4 & 6.7 PowerStroke diesels video

Clicky I've been watching his videos for about seven years although I have not seen this one until now. I recently sold a F350/7.3/6 speed truck and the buyer wanted to have it checked out. I had him take it to this guy in Buford, GA over a Ford dealer who sells new trucks... Yes he bought it.
While writing this I listen to this video and everything he says is right on as usual. Did not know he sold trucks he's repaired. Might sell my 02 F350/7.3/6 speed with 70K miles and have him build a truck.
