catch can not going to help with any i/c issues. thats for collecting oil fumes not coolant. most likley the i/c was never separeted and the high pressure system caused the leak. a res is easy enough to do i just never had the need. my manis are off all the time and my h/e has a rad cap to look into and add if needed
