I know this seems like an exhausted subject, but I've been searching for days and am entirely at a loss for what my issue is.
My 02 Mustang 3.8l Automatic with 160,000 miles has developed this horrid whine from the engine bay. It doesn't whine as I'm turning the wheel, but only as I rev/drive. It has a brand new power steering pump and pulley (even changed it twice incase it was defective), a brand new belt tensioner pulley and a brand new idler pulley. It doesn't make a difference whether or not the A/C is on or whether or not the car is in gear. It gets worse as the vehicle warms up. The whine is so loud that it's probably 3 times louder than my flowmaster exhaust and it's really quite annoying and embarrassing.
I pulled the cap on the power steering pump, and when manually revving the engine, it doesn't produce any air bubbles in the power steering fluid, so I'm fairly certain that the pump isn't the issue.
Any thoughts/ideas? I also have an audio recording that I could email to someone who may be able to get an idea from the type of whine but I cannot attach it to this thread due to forum upload limitations.
I used a stethoscope on the engine, pinpointing the whine to come directly from the power steering pump - but how many pumps do I need to go through to get one that doesn't whine?! Haha it's just irritating.
This spark plug deal... could it cause a whine through the power steering somehow, or would it create a new whine altogether?
