When my 351c warms up to about 190 degrees the purge outlet on the Moroso T filler starts to purge foamy coolant into the overflow tank.I would have thought by now all of the air in the system should have been purged.It settles down after a while and cooling has never been affected(175-180 when driving,190-210 idling).I do not seem to have a leak anywhere but this is concerning.I have a 16 lb cap on the T filler.Any thoughts? thanks;chuck
