Re: IML: freeze plugs in head on '67 440cid?

["Frederick Joslin" <fljoslin@xxxxxxxx>]

If you tighten up the top end you may notice more blow by because the compression should be better (higher).

I do not think that it will cause the rings to degrade faster, just it will be more noticable that they are worn.  

 

Also, if you rebuild the heads and later decide to rebuild the entire engine, the head work will not be wasted. It also gives you a chance to get in and actually measure the cylinder wear.

I feel a little better that it's probably not a bullet hole!

Any thoughts on this question? The engine is
very old, with OK compression and no blue smoke
out the pipes. I am just resurrecting her
right now. In a perfect world, I would pull
the motor for a rebuild. I would try to see
how she does first.

A valve job would tighten everything up on the
top end. Would that hasten problems at the
lower end, i.e.: rings?

I would rather postpone (for now) the inevitable engine rebuild. Comments?
