There are no apperent leaks, or puddles on the ground if the car is kept in place, ran and warmed up. Yet, if its driven it slowly looses coolant. The previous owner dumped a healthy amount of sealer in the system, which in my opinion is not a repair. The motor oil is not milky at all and there is no white smoke coming out the tailpipe. The oil fill cap and the valves (as can be seen through the valve cover are clean - not milky). I know these engines are very prone to blowing intake and head gaskets.

I haven't done a compression test, a leak-down test or a radiator pressure test yet. Am i missing something? Does anyone have any input or ideeas?

Thank you.

I think the first thing I would do is pressure check the system and see if you spot a leak while under pressure.
