added some more today, sight glass still looks frothy though, but pressures at approx 97 degrees in the garage are now 250-260 high and about 41 low. This was engine at idle, both fans running and a box fan infront of the car. This got me about 62 degrees from the cabin vents. took the car around the block and the temp came down to 55ish at the vents after about 5 minutes driving. Still think I'm low or should I be good?
