problem #3

Feb 152007

(reported on)

Bronco XLT 302

  • Automatic transmission
  • 140,000 miles


I have the same problem, only my bronco doesn't normally do it in city driving. It does it after I reach a certain rpm I assume, because it only seems to do it after I've been on the highway or expressway, even for a short distance. Then it will drop to zero until I park the truck for awhile. I replaced the oil presure switch (which is located on the engine block next to the oil filter on a 302) and it resolved the problem for a few short weeks they gradyually, it it got right back to doing the same thing. This is baffling because the truck runs like a good, no smoke or anything. I have noticed more oil than I would like to see in my airbox however. A local ford dealer pointed out to me that they keep these switches in stock, which indicates to him that the switches are problematic. Why else would they keep a part in stock for such an older car? Any clues or help on your end would be appreciated. I haven't figured this out yet and hope I don't have to replce the oil pump, or worse yet; blow the motor.

After the Vehicle warms up, it appears to be fine, but once I put the car into gear (it has an automatic btw) the oil pressure drops to 0 and the check engine light comes on, sometimes the engine quits on me also. when I am moving it seems to work fine but as soon as I come to a stop light it drops to 0, unless I put the car in neutral and rev up the motor a little.

Start up, run works fine. Oil pressure stays up. After warming up for 5 to 10 minutes, when stopping at a stop light, the engine oil pressure gauge goes to zero, and the check engine light comes on. Putting the rig in neutral brings the pressure gauge back up, along with revving up the engine.
