These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have a '99 Boxster, and it sat for a year or so. I drove it after having the dealer tune it up and changethe oil. I washed it and now I have a belt-like squeek coming from the engine. I removed the back window carpet and engine cover. I had the car running, and sprayed belt dressing on the belt at the front that goes to the alternator. The sound continued andis coming from the back of the engine. To reach this area, I will have to drive the back up on ramps. Any ideas on the cause?

POST 2Original post

If it is a chirping that changes in frequency with engine rpm's, probably a loose spark plug. It's a fairly common issue.

POST 4Original post

They are pretty easy to get to, jack up the back of the car and remove the rear wheels, and the fender liner that is toward the front of the car.

POST 5Original post

Does this only occur at idle or under deceleration by chance?

POST 6 / ORIGINAL POSTEROriginal post

The squeek started when I wash washing it, and power washed the Passenger Side Air Vent for the engine behind the door. The squeek makes a constant noise. It gets quieter as the car runs. Sometimes at start up, the vacuum from the Pass. Side vent is very high and you can hear that vacuum motor. Only like 5 minutes. I wonder if I got something wet. Please give me any ideas you have.
