When I compressed the spring the other day I noticed there was some play
when I moved the spring back and forth. Should there be any play and if so,
how much? What's the rule of thumb here?

Thanks,

Bill

 

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?

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

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.
