Did you use oem gaskets? I just replaced my own after having the dealership replace them for me three times. When I got in there I saw the original gaskets were made of plastic! What crap....
I replaced them with Rock brand gaskets and all is well now. I don't know which brand you used, but I'd like to know.
I'm a bit shocked to know that's the material the oems were made out of.
no wonder they cracked to pieces in a matter of about 1 year...
I have considered making new sets out of solid teflon if I have any more problems.
Would it be possible for you to post a link, or more info on these gaskets?
I'm familiar with Rockauto.com, is that where you bought them?
