You can see my mods in my sig. I just couldn't imagine I blew my HG's again. About 5 months ago I pulled the heads, took them to a shop and got them decked. Rebuilt my oil cooler, flushed the system and put in ELC coolant. So I would also be shocked if I had a clogged oil cooler. What are all the possible reasons coolant could be coming out of my degas bottle? Just put a new cap on it the other day and my actual bottle is only about a year old. If there is too much coolant in the system, will the pressure push it out of the top?
