As some of you may know, my Disco had the unfortunate event of head gasket/ slipped liner (?) failure and made the oil look like a milkshake. I am completely overhauling the engine with flanged liners and most of the internal bits. My question is about the external oil cooler. As I want to ensure the new engine is free of gycol contamination, I turn to the Land Rover community for advice about how to flush the cooler of the creamy oil slurry that currently resides within. I don't really have the funds to replace it (I wish I could), but would love some insight. I thought about just running it and changing the oil at short intervals initially, but would prefer to have an idea of if the engine has coolant leaking into the oil after the rebuild (not flushing would yield a false positive, making me instantly pull all my hair out and end up committed to a mental health facility). Thanks!
