Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

1998 Ford Explorer Owner Comments

problem #1

Sep 242009

Explorer XLT 4.0L Sohc V6

  • Automatic transmission
  • 135,000 miles


Upon diagnosis, cylinder #5 was misfiring. Checked compression on cylinder #5. Zippo. Something wrong with exhaust and/or intake valve. Lot of noise coming from timing chain area. Mechanic said fix would be easy $2K (new timing chain, cassette, new head, etc.) but recommends not doing it.. said it would just be a Band-Aid. Also seeing on this site people who've had repair similar to this one and then fails again in < 12 months. Recommended engine replacement (remember the existing engine has 135K miles on it). Used engine ~$3K but ones he is finding are all high mileage (e.g., 156K mi) and thinks that's a bad idea. Ford remanufactured engine would be ~$5K. But now I know this engine is genetically defective. While the vehicle is in otherwise excellent condition, these $ figures are beyond what it's worth (Edmund's TMV, Kelley BB, etc.). This thing is headed for the salvage yard. Replaced it with a used Toyota RAV4. I'm hugely disappointed in Ford after what I'm finding out about this engine and other Explorers. Someone should be shot. No more Fords.
