what would cause this
coldwater
Crazy Sr. Respected Jeeper
it sits outside all the time. i have no garage. when i got it the breather and pcv grommets were shot. the breather and pcv were just laying on the valve cover. so i got new grommets and pcv and breather. then i redid all the vaccum lines. this thing was in bad shape before i got it. so it probally got alot of moister in it. when i flushed the cooling system last fall all the coolent looked like rust. i flushed it for along time until i was coming out clear.
Now that I understand the actual FACTS! I'm pretty sure you're just fine and nothing at all to worry about.
