Problem: The car was diagnosed with a leaking head gasket & defective manifold. Cost to repair $2504.80 (I paid it) I brought the car in on 11/17/03 and got it back 11/20/03. I was told the repair was complete. As I drove it off the lot the car shimmied and stalled. The car was brought right back and they still are working on it as of 11/21/03 9am. History of problem at Ford: Ford has issued the following technical service bulletins for these two problems ( from www.alldata.com ) 03-6-2 Mar 03 engine - oil leak from R/H cylinder head gasket 02-1-4 Jan 02 engine head gasket - approved replacement procedures 01-21-10 Oct 01 engine - oil leaking from head gasket 02-2-2 intake manifold - cross-over channel coolant seepage according to www.lemonaidcars.com ( www.GM-V6lemons.com/mediaattn.htm )the Ford 4.7 liter has had these problems before and caused Ford to extend warranties to 6 yrs./ 75,000 miles on older models (www.autosafety.org/article.php?did=121&scid=59 ). they also know the manifold part used to original make the engine is defective. The repairs are costing me $2504.80 with no help from the dealer or manufacturer.
