Problem isn't the transmission, it's the engine. Sounds like it's overheating to me. Check the coolant, watch the temp guage, and go from there.

Sounds like you ruined the top end of the engine with the low oil pressure. The lifter noise may go away in a few days like the mechanic says, but that doesn't mean it's ok. They noise will come back, and the engine will not run right anymore. STP is fine as a stopgap, but you have ruined the engine, get rid of the car fast, you will need a new engine very soon if you don't.

Trust your mechanic on this one. It is possible that all is toast. With fresh oil the lifters should pump up fairly quickly. If they are damaged as may be the case, then they will continue to knock. I know it sounds horrible but please just start the engine, after checking the oil level agian, and let it run at idle. the STP is a nice idea. This thickens the oil and keeps lubricant on and in parts after the vehicle is turned off. The lifters are small hydraulic pumps that dampen the physical contact between the camshaft and the valves. I would be greatly concerned why all the oil ran out or was consumed. The vehicle is not old enough to be worn out. I would keep a quart of oil-say 10w40 in the car, and check the oil level every day for a while to see what is happening to your oil. While youare at it, check the coolant level too by actually removing the filler cap, COLD ENGINE ONLY, and looking in the radiator. I have a 99 explorer and it is losing coolant and the coolant recovery tank does not reflect a low level.
Good luck! Let us know if it clears up.

I wondered the same thing. My husband changes the oil and he can't remember when he changed it. It was important because if it ran out of oil in the time since he changed it there is another problem. I think what happened was our dash system was telling us it was time to change the oil and normally he resets it when he changes it but I think he may have turned it off to stop the warning, intending to change it and forgot. I'm not entirely sure. Someone said since he uses synthetic it may have helped prevent damage, it was never smoking and I only went up the street to the mechanic. The noise seems to have lessened since we put the STP in yesterday but hasn't gone away yet. The mechanic quoted us around $550 to replace the lifters if necessary. I mainly wanted to make sure that the mechanic was right about not causing more damage by driving it with the noise. I will be adding oil changes to my responsibilities! Thanks for your help.

I just ran into the same situation this week and still have not figured out why after 2 or 3 minutes after you start the vehicle that the check the charging system display lights up * I just replaced the belt today to see if it helped * it worked for about 10-15 minutes before that crazy display came on again * I replaced the alternator that was faulty , recharged battery for 12-13 hours and thought it was an easy repair until this display issue keeps coming back * Any help would be greatly appreciated ** THX

#6336 of 6385 incredibly loud humming by johnnykool

Nov 19, 2011 (5:36 pm)

I have a 2001 Ford explorer XLT. It started making the incredibly loud humming noise after i hit around 30 mph. I noticed my ball joint was bad so i changed it and rotatedm y tires thinking that would have been the issue. The sound got softer for around a week and now it is right back to be extremely loud. What else could this be. I heard maybe the wheel bearing but im not for sure and i really cant afford to put the money into it just to figure out that its not the wheel bearing. The only other thing i could think maybe had something to do with it is the fact i took the 4-wheel drive shaft off to redo the joints on it and the upper joint fell out and i have yet to replace it so its been out for over a month now. Does anyone have any suggestions or can anyone help me out in any way. It would be great.

Start with this. Check the voltage at the battery with engine off. Write it down. Start the engine check it again and write it down. wait for batt light to come on and check it again to compare. You want to rule out 2 things, the battery is defective, not charging=12.25-12.75 volts. Motor running= 13-14 volts, and that the new alternator is actually working. I am thinking you have a bad connection coming off of the alternator. Caution- WATCH YOUR HANDS AROUND THE ALTERNATOR WITH THE ENGINE RUNNING.
After charging the battery for several hours it may retain enough voltage to not que the batt.light for a few minutes. Of course this means the altemator is not working or the connection to it is faulty.
