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
Stock heads run it hard they will be fine. Absolute worst case the guides get so bad that it drops a valve, Happened on one of mine!
