I am going through the same process you are right now. Ford Reman is about $4,000 in a crate and comes with a three year warrantee. At minimum, you need the Ford Phasers and the guides. Ford claims they have fixed the problem. The second thing that is mandatory is a Melling Heavy duty Oil pump. New water pump and I would go with Ford for these. A lot of guys have purchased a complete Timing Chain kit that is Ford OEM for about $850 on Amazon. I also did a check of local machine shops and narrowed it down to three shops. Did a Better Business Bureau check and honed in on one shop. They have mechanics there that will so a R&R for about a Thousand Dollars. Other shops seem to go $2,000 to $3,000 for the Ford Dealership. The book calls for about 8-12 hours so you are probably just wasting money at a Dealership. Most guys on this forum are pretty good with a wrench so if you are mechanically inclined, they can walk you through it with a little help from YouTube.
I know these cars kind of grow on you and I bought my 2005 new off the show room floor. It was my wife's car for all of these 13 years so when it hit 215,000 and decided to find another one just like the original one. Same color, Eddie Bauer and 100,000 miles less and rust free. Interior is immaculate. I decided to rebuild her and drop a Reman engine in her. These things are a work of art and sometimes its hard to let something you love get away. Remember your first girlfriend? There are some you probably would like to get back. So before you go and dump this thing of beauty, consider rebuilding her from the ground up if needed. After all, sixty thousand for a new one is not cheap. You can do a lot of rebuilding for sixty grand.
