    Well there's yer problem! When you replace that valve check the line to make sure it's not developed any breaks.

  • @GdD I wish that was the only problem with this old rust bucket.

    As a previous rust bucket owner my advice would be to look at your potential spend and decide whether to invest that money in what you have or something newer. I made the mistake of sinking a lot of money in an old car with loads of problems when I could have spent it on something more reliable. I ended up with loads of problems I couldn't fix myself in my front yard.

It's a Positive Crankcase Ventilation (PCV) valve. Not sure which engine you have or I would have given you a couple of part numbers.

Well, guess I can give you both:

4-cyl

  • FRAM FV200
  • Standard Motor Products V207

6-cyl

  • Standard Motor Products V236
  • WVE 6P1016
