I got a good laugh today... All the grief I went through getting the O rings replaced and fighting with my Ford dealer was for nothing!
Dropped ******** this morning to have the seat bolt recall done (for those of you who don't know, apparently the two bolts in the driverside 98 and up X's can break, especially in an accident, causing the seat to snap) and they called me and asked if I wanted the Chain tensioner recall done too.
This is the same dealer who, a year ago, gave me crap about this recall and flat out refused to replace the O rings because I was 3K miles over the limit, mind you. I know the chain tensioner gets replaced with the same crappy part and Jack's was going south again, so I played dumb blonde and said "Oh sure, go ahead and fix whatever you need to!"
Somehow I managed to get not only a new tensioner, but new upper and lower intake O rings, front cylinder cover gasket (I'm typing this verbatim from the service sheet, no idea what some of this is), Shift sprocket-front, and a few other seals who's names I can't decipher, lol.
All that arguing and then they go and fix all for free. They said it was covered up to 100K miles...either they don't know better or Ford changed the recall mileage from 75,000.
Jack absolutely purrs now, even though they politely added a quart of regular oil....I run synthetic
If you're having serious cold start problems, go to your dealer and give 'em a shot, it's worth it!
