Leaky valve seals


The New Kid
I’ve determined my valve guides/seals are junk. Stock heads. Could have 169,000 miles on them. It just smokes at idle and on a hot startup. Am I going to hurt anything by just keeping running the car this way? I don’t really care nor do I have the money to get the heads milled for exhaust seals. I have champion irons but I’m not putting those heads on a worn out bottom end. Can I just run the car and top off the oil every now and then? It’s not fouling the plugs or anything. Just Smokey. Thanks
