Our '48 ranch jeep with the 225 suddenly started blowing oil around the oil filter gasket yesterday. I've never even heard of anything like this. What could be the cause? We drove it several hours two weeks ago and had no problem what so ever. It happens so fast that the pressure gauge doesn't have time to show the pressure. I won't be able to get back to the ranch for a few days so it will take me some time to investigate any suggestions you might have. Forgot to mention that we changed the filter and made sure the surface where the gasket met the block was clean but it that had been the problem it would have show up before.
