I purchased my 2008 6.4 powerstroke with 136,000 miles 2 months ago. In the past two months, its been in the shop 5 times for a total of around $5000. First was a bad fuel line. had to lift the cab to replace. the other 4 times were broken rocker arms and bent push rods. I'm tired of fooling with it and have decided to replace the whole engine. I figure it needing a valve job and the possibility of metal shavings working their way down to the bottom end justifies the extra money. Where's the best place to get a crate engine? Also, I need to know EXACTLY what all it comes with and what I would have to reuse. I make my money with this truck by hauling my landscaping equipment so the longer it's down, the more money I lose. I appreciate any and all help. I need this beast fixed!
