In the last week I have noticed that my ’02 Explorer – V6 makes a brief loud rattling noise during a cold start-up. When the engine is warm, it restarts normally.
I am wondering if the oil filter has an anti drain back valve, and that it has failed?
My other car has an ADV equipped filter and the valve in it failed a few months ago. The resulting noise was a light cam knock until the oil pumped back up into the engine. Replacing the filter fixed the problem.
The noise my Explorer makes is louder, but very brief, less than a second I would estimate.
The weather has turned colder, but I am not sure how that would affect the cause of this new noise. I use Shell Rotella T Syn, 5w-40 with a Purolator oil filter in this vehicle.
Since my wife and I are commuting to work together now, and both children are off in college, the Explorer mostly sits in the garage, except for some usage on the weekends. So, it is lightly used these days, making a new mechanical problem a surprise, since like I said, it mostly just sits in the garage.
Do any of you know if the filters on V6 Explorers have the ADV? That would make this problem easy to fix, so I hope that is the problem.
Thanks!
