    Combustion Chamber Bowling

    Carbides are on their way courtesy of Bezos and I'd like some opinions before shredding my heads. Yes, the consensus is the ports aren't great but the bowl design is abhorrent. It's almost like Ford intentionally shrouded the intake valve just for the 2.9. For reference: 2.8 vs 2.9 vs 4.0...

    2.5L ('98-'01) Stuck engine RPMs until dead stop - gone fishing

    The truck is a '98 XLT with the 2.5l 4cyl, manual. When driving (hot or cold, highway or in town, 25ft or 200 miles) the engine speed stays high, or goes higher, when depressing the clutch. It will stay there, no matter what, never come down, until the truck comes to a dead stop. I've coasted...
  3. 4.0L Valve Cover Leaks!!!

    So today in a few hours I'm replacing the valve cover gaskets on my ol beautiful 2001 XLT 4.0 (or at least I'm starting the work today). Does anybody have any suggestions as to what else I should/could replace while I have the valve covers off? Anybody have any tips for this job? Help is...
  4. Starting issues, repeated leaks in heater core valve

    Update: My video and post refer to the leak as a possible cause for my starting issues. I just realized the starter and the leaking valve are on opposite sides. Trouble still there, likely the starter then, and the leak as a separate issue... Why does that valve keep going bad? I had trouble...
  5. Valve Cover Ranger 2000

  6. A/C Low Side Ball-Bearing Valve Replacement

    I just bought a low side valve that screws into the top of the a/c accumulator on my 1997 Ranger. Quick question: How is the frick do I get the old valve removed? I tried simply taking a pair of pliers to the base of it and turning. That didn't do a thing. I figured I'll try putting some...
  7. Heater Control Valve Vacuum Leak

    Hey guys, I have a 1997 ranger xlt with the 2.3. I found out today that I have a vacuum leak that is keeping my heater control valve from opening up, so no coolant gets to the heater core. I can't seem to find the right vacuum diagram to figure out where the vacuum hoses go either. I believe it...
  8. 3.0 flex-fuel V-6 - 2003 model XLT

    Hello, Two months ago, I purchased a 2003 Ranger XLT with the 3.0 motor in it. It was perfect, like brand new. I was very happy with it. Yesterday it started a ticking noise in the passenger side head, sounded like a valve was, maybe, hitting the top of the piston. I believe that whatever...

  10. Valve Lash Madness

    Valve Lash, Feeler VS Dial Gage Gone around both sides twice and still ticking like mad. Using my feeler gage is tough as I believe the area where the rocker arms contact the valve stems are pretty beat up. What I was wondering, Has anyone used a dial gage to set valve lash? What I was...
  11. 1998 2.5L EGR Connector Problems

    The other day I was attempting to take off the EGR valve and before I got to it, i broke the plastic connector that hooks up to it. I've been trying to find another one online but I can't seem to locate one. I also went to my local O'Reilly parts store but was told they didn't carry the part...
  12. PVC valve location. NEED HELP!

    I've looked on all the threads i could find but none of them seem to get me even close. I need to find the PCV valve on my 2007 2.3L I4. PICTURES WOULD BE BEST. But if you have a really detailed description it might help too. I've looked all over this engine and I can't seem to find the damn...
