Re: Packard engine coolant

Thanks guys for all the ideas put forth so far.
I need to fill in some gaps about the motor. It has had a major overhaul. New pistons, valves, main and big end bearings,valve guides,cylinders re-bored and one re-sleeved.The side water jacket was renewed.A new honeycomb radiator fitted. Coil has been rewound. New timing chain and the sump repaired. About the only thing that has let the job down is the condition of the cooling system.
When I first drove it for the registration inspection it "vomited" for want of a better word and mud went everywhere - thick enough to appear like custard or jam. I have cleaned and flushed the system and have tried some coolant additive that lowers the water surface tension and lowers the running temperature by a few degrees. This has helped but not completely. I think the head especially is still quite dirty inside although not much debris or colour appears after a flush.
Couple of extra pics. My folks with the Packard during their courting days about 1948.
The engine block having the water jacket surface machined.
