Re: How much play should a valve stem have?
Does this engine have decent compression? How may miles?
There shouldn't be very much play in the stems. They are inside brass
guides and the guides do wear out. When worn out, it is a waste of time
to put new seals in it, they will wear out or pop off fast.
Are you chasing symptoms of worn out valves?

Re: How much play should a valve stem have?
The compression readings my mechanic gave me were 150 psi across all
cylinders. I'm getting blue smoke after idling for a few minutes when I
press on the gas. It doesn't smoke when keep the gas peddle down for a
length of time. So I'm chasing symptoms of worn valve seals according to
what I've learned.
Can the brass guides be replaced and if so how much of a job is that? Does
the head need to be removed to replace the guides? These are exploratory
questions.
Thanks,
Bill

Re: How much play should a valve stem have?
You are basically talking a valve job. The seals are fairly easy, the
fix just might not last a long time if the valve guides are sloppy.
