Hi All,
My wife's 94 Explorer is making a light whining sound from the engine that occurs only when the engine is cold. It goes away whithin 2 minutes of start up. The Ford dealership says the sound is the oil synchronizer shaft, which I have never heard of. Apparently, if it siezes the oil pump stops and the engine siezes soon after. The dealer says that he cannot predict if this will happen sooner or later. He also says that fixing it will require dropping the engine.
The question is: does it need to be replaced. I am more concerened with my wife's safety than the cost. I view the dropping of the engine as a possible issue, as well. Will that also introduce problems?
Thanks for any help.
Rick
