Short Squeak on start-up

[Gent]

So my 2k 2.7l Boxster started squeaking recently.

Intermittently on startup, then after starting out whether in 1st or reverse - seemingly just as, and just after some engine load.

I took it in to Vancouver West Motors, and they couldn't get it to happen. They checked the belt, and pulleys. Even tried a different belt, no problem. Took it for a "spirited boot" with the covers off, still no sign of it. Spark plugs and AOS are fine.

There was no charge, but I was able to produce the squeak on the third and fourth start for them when I picked it up. They asked me to get back to them on Monday.

It does seem to become more common after I have fun, quick driving and high rpm rev matching.

Any suggestions on a direction to point them?

My brothers 99 2.5L developed a squeak or chirp on one side of the motor after a track session or spirited canyon carving. Definitely internal. Our trusted indy found seriously worn timing chain tensioner guides. 18 hours of labor later the problem is resolved. His car was probably a few thousand miles away from Ka-Boom. Whew! Bullet dodged.

Christ, I hope there's a cheaper and less frightening reason!
