AB. | had a 13.5 with this issue, they did the head bolts with rubber, 300 hrs later there is some residue in the coolant tank, but not enough I think it is leaking still. Almost impossible to get it flushed clean I would think. Was told the only place oil could get in the coolant was the head bolts as an oil galley goes through 2 head bolts, oil pressure higher than coolant pressure, travels down the head bolt and penetrates the head gasket. | |
