Seems the oil modine is fine, I just plumbed it into mains pressure and thats not leaking at all. I dont want to put it back on the car though, anybody doing anything different with their oil and water ways, I think PON did away with his Modine but i cant find it in a search? I had a look at the bores and they are clean, oiled and crack free where I can see so its time for the turbo to be checked and then maybe a bottom end rebuild??
