- 2011ford explorer ltd
Hi, everyone. I'm new here. I've got a 2011 V6, Ford explorer that has being giving me issues since last week.
I bought the car used from a cousin of mine. Car was driven down to my destination working perfectly, only some few weeks after, to start here some knocking sound from the engine. Took it to a treeshade Mechanic down the street, who said the oil pump was weak, and acting weirdly. They did replaced the pump with a used one I got off a junkyard.
When I got the car back, these were the symptoms I was having:
1. On start-up, there's a noise that comes from the engine area. Don't know if its the valve train or engine block vicinity.
The noise persists for sometime, before subsiding.
2. Revving the engine when its idling, you hear a noise at the end of the throttling. Kind of a feeling of maybe the conrod bearings, or crankshaft journal bearings might be worn, or so.
3. At this idling position, the engine kinda gives a feeling of a diesel engine (maybe misfires). Feels as if its jerking. A to fro like motion.
4. When driving, immediately the AC system is engaged, with time, the engine shuts down, as some kind of failsafe system. If I start the car immediately, it comes on.
WHAT I HAVE DONE
1. Scanned the car for codes, and got:
*P0012 and P0016 all pointing to camshaft A and B retarded or advanced timing.
I removed the VCT solenoids on all the banks, and discovered they were all clogged with metal chippings, and sludge.
Cleaned them up with throttle cleaner, and applied 12V to test them few seconds. The plungers in the solenoids were working; fixed them back, and all the codes went away by themselves.
I only have codes for the oxygen heater sensors alone(this won't cause the stalling problems).
2. I did replaced the fuel pump, because it was so dirty.
There was no improvement.
3. I ha e checked the oil filter on the truck. Its the motorcraft filter that was installed there.
MY QUESTIONS ARE
Could it be that the oil pump that was replaced on the engine has low oil pressure problems, or what?
Can we say, the knocking noises I hear when the engine is revved might be what's causing the "low oil pressure$ to show on the dashboard, and subsequent stalling of the engine when AC system is ON?
Pls I need your help to help fix this car. Its being giving me sleepless nights.

. If the oil drained has quite a bit of metal its not going to be good, could try dropping the pan and removing any remaining shavings off the oil pickup strainer.
