In engines with no valve guides, just holes bores in the block, when worn there are two methods of repair.. First is to bore out and install cast iron valve guides such as we are familiar in our Packards. Second is bronze "valve liners" alao known as valve guides. They ahve rings machined into them to retain oil and work very well.


I've never heard of bronze liners used in cast iron guides but I'm not up on the latest. Sounds good.
