Had a second valve stem blow out on my 64 this week do to cracking. Some research online shows there was a huge batch of Chinese-made valve stems that made it out into market between 2006 and 2008 sold under Dill Air Control Products name. If you had tires mounted between that rough timeframe, check the valve stems for cracking/slow leaks etc. Mine have both basically cracked and let all the air out very quickly while the car was in the garage. Could be pretty dangerous on the freeway.

Looks like Dill's server is down right now but it was up this morning. Here is the PDF released by the company explaining the issue and what to look for. Also calls out the affected model numbers.

3 of the 4 valve stems on my mom's 97 accord blew within the past year. Not expensive to replace but annoying when you get a flat.
