did you recently change something? Mine did that after i changed the thermo., and it ended up being that the thermo. was slightly out of its place and caused a little leak.

havent changed the tstat yet but i am tomorrow...but i just went out and checked my intake bolts and the bolt that was closest to the puddle was loose....so i guess with only 3,000 miles things are starting to wear and loosen up a little...i'll check them all tomorrow and hopefully thats all it is

thanks merrill

when my car was running rich we added timing to it to lean it out. evrey motor is different. in ur case it could jsut be a tempory solution. whats ur timing set at now?
