I have a windastar with 148000 miles. When I drive it sounds like an airplane engine.
The faster I drive the louder it gets. Any ideas about why?
Check the duct that brings air into the engine. If this cmes loose, then you hear the engine sucking in air. If the intake air is bypassing the air cleaner, then you are sucking unfiltered air into the engine. This should be a big hose about 3 inches in diameter. I had this problem with a Ford Tempo I once owned. The plastic clamp supplied by the factory didn’t do the job, so I bought a stainless steel turret clamp which did the job. If this is your problem, it is an easy fix, but do it immediately.
What kind of airplane?
Wind-a-star.
