Having an ongoing issue with the engine pumping all the oil into the cooling system. Brand new headgasket, arp studs, head was checked and surfaced when taken off, egr has been deleted, oil cooler is new. The jeep runs for 5-10 minutes and in that time will pump the oil from the pan into the coolant. Every single time. Am I dealing with a cracked block? Lost at where to go. Jeep was inherited from my uncle and really want it get it going again. But running out of money trying to fix it. Any insight is much appreciated.
