After talking with George... we are pretty sure that the crisco build up was from too much crankcase pressure, due to constrictive breather hose size. Oil vapor and steam make that ''crisco'' build up. makes sense, because I am not burning oil, nor am I burning coolant. Going to try pulling off the valve covers, and putting bigger 5/8 barbes on there, and taking everything from 3/8 to 5/8 including the hose. Should free the breathing up enough to get rid of the excess crankcase pressure. I will try it ASAP.
