I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?

Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.

For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.

you do not torque valve covers down, buy a new gasket , I would get a good quality rubber one and some blue rtv sealer, clean any crap off the valve cover no glue no bits of gasket nothing, same thing on the head surface, glue the gasket on the valve cover, let it set, then carefully put it on, start with the bolts in the middle and work out finger tight all of them, then just snug the bolts down, dont crush the gasket, you can also use a light duty locktite to hold them in place, and often times old valve covers are warped, it is too your advantage to make sure its as flat as you can get it, or spend a few bucks a buy a new one. your choice, but snug the nuts down good with out crushing and bending the thin sheet metal of the valve cover.
