I have changed the lim gasket on all the 3 GM V6's we have owned in the last year.
I have all the materials to do this (except the tools) and I reeeeally want to but I'm petrified of messing something up. I've watched that DuBob video three times and I'm still just not confident enough to do it. Can I drive up to MA? LOL
