Default #3 cylinder - 0 compression

Have a 2003 LE, 141k miles. Took it to the shop for a blinking CEL and they're telling me the #3 cylinder has no compression and they need to pull the head to determine the extent of the trouble.

Wondering (hoping) if there's a chance it's a stuck valve and can be remedied with an additive since there's no way I can pour $1200 into this car.

Anybody have any experience that might be helpful?

No, but if you are so inclined, simply spend the couple bucks on the additive and see what happens. I don't hold out much hope for that, but if it will make you feel all warm and fuzzy inside knowing you tried, go for it. Like I said, you'll only be out a couple bucks.

Moving on now.

Cool Re: #3 cylinder - 0 compression

If you have 'zero' compression,the chances are it is a 'stuck' valve,if it was a 'sticking' valve,an additive might be a nice temporary fix.......But,once a valve is already stuck(open or closed),I don't see an 'easy fix'.
If still looking for hope,you might want to take a glance at this for suggestions:

It's much more likely a burnt valve, they're really not very expensive, but include removing the head.

Pulling the valve cover off isn't difficult or expensive, so it wouldn't be a big deal to do that and see what's going on. I gotta believe if they've already done a compression test you're 80% of the way there anyway - pulling the valve cover would just be a matter of sliding the power steering reservoir to the side and removing a few bolts. A stuck valve would be fairly easy to diagnose at that point.
