<VV> HELP!... push rod tubes...

[Dan & Synde]

Hi Cash,

I'd describe all the pushrod tubes I've ever installed as a "firm fit".
Usually, if properly lubed with oil or white lithium grease, I can push them
into place but it takes some effort.  They tend to "pop" into place as
others have described.  

Besides everything else that has been suggested as the cause for the
looseness, is it possible that the bores the the pushrods fit into have been
enlarged in someway?  Perhaps to clean up some damage to the bore?  Perhaps
someone in the past was a little over zealous with the cleanup process?
I've had to touch up the bores on heads and blocks before and it wouldn't
take much to accidently go too far.  Just a thought, you might want to check
it with a bore gauge.
