Gas Cap Gasket Gone Bad?

[david1walker]

My '95 LS has the original gas cap and gasket. Do these things need to be changed for any reason? I have noticed that when I unscrew it to get gas when it is low on gas...it spews air for about 2 or 3 seconds.

I thought I read somewhere in a thread at one point that it shouldn't be doing this, etc...

Anybody have any insight if there is a logical reason to replace these caps and/or gaskets, and if you gain anything by doing so?

Thanks!

Spewing air for several seconds is normal and probably indicates that your gasket is doing it's job. If you had a check engine light on or something like that, the cap gasket might be suspect but since you report no such issues, I would just leave the original gasket alone. Only if it has some tears or obvious cracks would I replace.
