How long did it take you? Mine is leaking as well. I've been thinking that if I need to get down to the block, then maybe this is the time to bump up the cc's a little bit while I am at it.
10 minutes ago i just finished putting a new base gasket on the 07 with 2100 miles. I used a 2010 base gasket. My 98 has 7500 miles and no base gasket leak yet.
