Anybody ever work on the oil cooler on a 525? If so how did you do it? Mine has a leak I think on the inlet neck. Checked the hose and it's good and changed the gasket on the end cap of the cooler, too, but still have a leak. I want to pull the cooler but can't find any easy way to get it out. It's on a 382 Formula Fastech, any suggestions how?
