Re: Cylinder and piston wear

Thanks to all! The crack is external, about two inches long, on the drivers side of the block between cylinders four and five. There is a picture below. It weeps water cold.

How do I measure for worn valve guides? Is it lateral motion of a valve placed in the guide, measured with a dial indicator, or is it diameter of the valve guide? I also have one valve guide (#2 exhaust) that is raised up quite a bit. I was planning on just pushing it back down. Interestingly enough, this was not one of my broken valve springs. Any thoughts on what to drive it back down with? In the absence of the special Packard tool, I was planning on using a hardwood dowel or brass drift punch, to avoid mushrooming the guide.

EDIT: The valve guide is not clipped; it is raised up.

My generic engine overhaul book just got here today, so I'll read up some more before I finish my inspections.
