I recently just got my civic back. i sold it about a year ago and they guy wrecked it so i bought it back hoping to finish what i started. the radiator has a crack in the top so its not holding coolant. i had to drive it about 2 miles home and i filed up with as much coolant as possible the whole ride home the temp stayed where it was supposed to but when i parked it i noticed some oil slightly bubbling from behind the exhaust manifold gasket. i have dc 1.5" headers and i had never noticed this before but i think it could be because it hasnt had an oil change in over a year because its just been sitting. so could the oil have thinned out and boiled a little? please help ive never seen this happen before.

 

check to see if the valve cover gasket might be leaking, or any oil seeping near the exhaust area. There also might be residual oil baking. try cleaning it up good and see if there might be a minor leak.

 

will do. the valve cover gasket is probably bad its been sitting for over a year. ill try those things and if it does it again then i guess ill be pulling the head haha.

 

i cleaned the whole motor up it was just water from rain it didnt have a hood for about a week it ran down the motor and turned black then sat in little pocket.. when it heated up it boiled but no major concern. thanks
