david1walker Posted November 9, 2012 Share Posted November 9, 2012 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!

landar Posted November 9, 2012 Share Posted November 9, 2012 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. Quote Link to comment Share on other sites More sharing options...
