Anyone who remembers way back when will remember what heater and rad hoses did on an engine when either the oil entered the coolant or the trans cooler pumped fluid into it. Those old hoses made of rubber swelled up like balloons it was oftened the first thing to tip off a problem. Big old swollen hoses bulging, near the end of the cycle the oil would actualy start seeping thru the hoses. Made a nasty mess of things. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrc II " Chronic Pain Hurts" -------------- Original message ---------------------- From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) > iirc rubber parts - hoses and seals - have to be compatible with > either svo or biodiesel. synthetics used for a long time now are, but > your '59 would indeed probably need some r&r. > ________________________________________________________________________ > Andrew Hay the genius nature > internet rambler is to see what all have seen > adh@xxxxxxxxxxxxxxxxx and think what none thought > _______________________________________________ > Amc-list mailing list > Amc-list@xxxxxxxxxxxx > http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
