This is a generic item so I searched the Internet. I found adivice on why and how but not when. My Festiva owner's manual says don't adjust the valves unless they are noisy. My Festiva, being a small car, is naturally noisy. Do valves have a characteristic noise I can listen for? Is there some other symptom of loose valves I can look for? I hooked up a hand held vacuum guage and the needle is rock solid. No movment to suggest any valve or other engine problems. I was doing a minor tuneup today and could not decide if the engine was more nolisy than usual or not. I should spend more time under the hood getting to know to sound of the engine. Thanks.

One will be making more noise than the others like on my '89. They are naturally noisy because they have lash unlike HLAs. Vintage!Comment

Mechanical valve lifters have a sound kind of like tapping a screw driver blade on your intake manifold. With 8 valves, it's going to sound like 8 screw drivers tapping one after another very quickly. Some people say it sounds kind of like a sewing machine. Regardless, the tap sounds should all be of equal volume. You shouldn't be able to notice one sounding louder than another.Originally posted by WmWatt View PostYou gonna race that thing?

You can check/adjust them whenever or as often as you want, although it may not always need it. If they are too far out of adjustment your power & MPG can suffer slightly. It sounds like it's never been done on your car (at least to your knowledge), so I would probably adjust them. When I had my '79 Fiesta, I used to check & adjust them once a year (usually in the spring)Brian
