  • Q:

    I came out and started my 1998 ford explorer V6 and it sounds like the motor is knocking/a lifter is tapping but it has never made a noise before at all, I literally drove it no knocking what so ever turned it off went in the house for a few hours came out started it and its knocking/a lifter tapping and its quite loud. I imediatly turned it off checked the oil and added 1/4 a quart(oil needs to be changed) . But because Im a disabled single mom with no family/no reliable or helpful friends so I had no choice so I drove to the grocery store, when I came out and started it there is no knocking/tapping at all. Is it that my oil pump is out? or is it going out? PLEASE HELP!!!!! ANY HELP OR THOUGHTS/SUGGESTIONS, ETC. will be greatly appreciated. Thank you in advance and bless you!

      Yes, it seems the oil pump is wearing out. The first sign of trouble may be a low oil pressure warning light, a drop in the normal reading on you oil pressure gauge (if your car has one), or the appearance of ticking or clattering sounds from your engine. As a rule, most engines only need about 10 PSI of oil pressure for every 1,000 RPM of engine speed. Oil pressure will read higher than normal when a cold engine is first started because the oil is thick. Oil pressure will gradually drop as the engine warms up and the oil thins out. So normal oil pressure on a warm engine cruising down the highway is typically 30 PSI up to 45 PSI. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

    where is the oil pupmp located and how do you replace it (1989 ford bronco II)

      The Oil pump in a 1989 Ford Bronco II is located in the oil pan. Put the drain pan under the oil pan. Unbolt the drain plug on the oil pan and let the oil pan drain out. Reattach the drain plug on the oil pan once the oil has drained. Unbolt the oil pan from the engine with the 3/8-inch ratchet, extension and socket. Drop the pan to reveal the oil pump. Unbolt the pump screen from the end of the pump with the 3/8-inch ratchet and socket. Installation is the reverse process. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.

      Unfortunately, since we can not be there with your vehicle, we are unable to diagnose why your vehicle is showing no oil pressure.

  • Q:

    I have no oil pressure at an idle but have it when you give it throttle. It only does this when the engine is warm. It has full pressure when it is cold. Is this the oil pump problem?
