Leaky valve seals

[TireFryer]

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

if its just smokey on startup i wouldn't lose any sleep over it. i don't even run seals on the exhaust valves.

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!

Easy to put new seals on the intake guides
