I'm a 52 year old lady who just purchased my parents homestead. I have a sentimental attachment I guess you could say to my Case 446, which was my fathers. When I'm on it, that is what I call 'papa time'. Last year it blew, and we took it to a small engine repair shop. To make a long story short, it was there over a year, and when we got it back, after being 'rebuilt', it ran great, for a few minutes any way! Then it blew oil out the exhaust and there was oil every where. They said they could run it for two hours before it blew oil. Anyway, when I found this site, I though maybe someone would have an idea of what was causing this to happen. It still runs great when you start it up, but sooner of later, it will blow oil again. Good news, we got our $500 back! But I really want my tractor running. It is a Case 446, and there is nothing better that riding the tractor on the farm!
