OK this past weekend i was doing some general checking (looking and poking around in my engine ) keep in mind i have looked at this before all seemed normal anyway i opened my radiator cap and i had some brownish clay looking stuff in my radiator long story short i would like to get your opinion on what you think it could be..
ADDITIONAL INFO- me and a buddy of mine flushed it like 3 times also lets go ahead and rule out HG its not that its not in my oil tank or under the oil cap after that my radiator hoses top and bottom when the car is cool are flat MY GP HAS NEVER OVERHEATED
Thanks.
