I have a 01 LS1 motor that I'm worken on.I cant figure out these valve cover gaskets.What I atempted to reinstall the old ones they were about 1 inch to long,so I bought new ones and went to install that one it was the same length.Is there something I'm missing????This is a realy stupid question but cant figure it out.

 

u are streching them to much

 

I just removed them out of the plastic bag.....they were never stretched

 

you have to squish (compress) them while installing. they are made too long so that once installed they will seal better.
