Question about 1998 Ford Windstar

1 Answer

No Oil Pressure

I have a 1998 Ford Windstar, 3.0 engine and around 140k miles. My wife was coming home and the oil light came on. She continued to bring it home and when I checked it the oil was full and I didn't hear any rod knocking. I changer the sending unit and the light still didn't go off. I then attatched a gauge to the engine and had zero pressure. I can blow through the tube of the pressure gauge so there is no blockage there. I replaced the pump and even installed new bearings. still no pressure. I can hear little if any knock. Where do I go next?

    Forgot to add I have also changed the oil and filter when I did the pump / bearings.

  • jambowser Jan 16, 2009

    When I had the oil gauge connected I could blow through it with no problem. I also put about 4 foot of wire through the hole as well to see if anything was blocked. If the hole was blocked I wouldn't think this would be possible. It still starts right up and seems to run ok. I had it run at various rpm and don't hear and odd noises.

    This sounds most likely. I'll have to check this. How do I check this?

    Sounds like u may have spun a camshaft bearing, this would block the oil gallery hole.

Did you check the synchronizer assy? It is the piece with the cam sensor on top in place of the distributor. These have a tendency of breaking. It also drives the oil pump.

Oil light comes on in my ford 2001 windstar se, oil was just changed and level is fine

It may be your oil pressure switch that has failed. However, if you hear any ticking or knocking, it could be cause you aren't getting oil pressure in which case damage to the engine will occur.

I've spoken to several mechanics on my Explorer. I lost oil pressure and drove it home from work around 30 miles, it started knocking really bad. I had just changed the oil, they are stating I wou

Yes, I agree. Overhaul, or new engine time. Loud knocking indicates your crankshaft bearings are toast-it won't be long before a piston rod goes through the block, or the engine siezes up. Overhauling an engine with a bad knocking means a complete teardown and rebuild-very time-consuming, labor intensive, and very, very expensive. You might want to consider a used replacement engine with low miles as a cheaper alternative. Good luck.

No if the oil light has flickered you have oil pressure loss some time just belive the sensor do help us out. lifter do not cause oil pressure loss pressure is built in the rotation of the crankshaft. The knock under the plenum will point you to that cylinder that is affected, (main bearing) as for a 1995 the injectors can only cause a misfire but no knocking noise,will they honor the warranty

Burning oil...what oil to use in 1998 olds aurora 140K miles

Many engines begin to drink oil at or around 100K miles. I found that Castrol GTX High Mileage oil will get me to the next oil change (at 5K miles) without having to add a drop, where as before I made the switch I was having to add two quarts just to get there with the generic stuff.

I have a knocking sound in the engine when I first start it up that goes away after a few minutes. 1998 Ford Windstar with about 116,000.

Is it a low down in the engine toc, toc, toc or a lighter tic, tic , tic sound?
The lower one is quite often the main bearings, rather than pulling the engine to fix it run 10W30 oil in it instead of 5W30 and treat the old lady with respect and don't rev or drive her till the knocking stops. It stops because the oil pressure has build up. If it is the lighter ticking this is the hydraulic lifters, don't worry about it, just do the same. Make sure you don't go longer than about 4000 miles between oil changes. I put Synthetic blend in all my cars and run 5000 miles between changes.
Hope this helps.
