Valve seal replacement

Postby Lt.Mike » Mon Jun 19, 2017 7:47 pm

For the better most part my A runs very well. I have two issues with it though that both involve oil leaks. The first is that a new valve cover gasket is needed. The second is that the tractor smokes heavily when first started but clears up in short order. I suspect the valve seals need replacement.
How much of a job am I looking at and can I get this done without taking the head off like can be done with a chevy v8?

you can use an air hold adapter, it replaces the spark plug holding the valve in place while the seal is changed, make sure that the oil returns in the head are not plugged up causing the smoking issue

Ok that's why it's good to ask questions. I will check the oil returns first. For the first few minutes there's enough smoke to think I'm burning the shed down. The longer it sits stored the worse it is.
It'd probably be a good idea to flush the engine while I'm at it.
