1947 Chrysler Windsor Valve grind

Iam looking at doing  the valves  (with the engine in the car). Is this possible & what would be the procedure?

Definitely this is done with the engine in the car. You need to remove the head and it helps to remove the intake and exhaust as an assembly for better access.

 

An auto machine shop can do a lot better job than you can at home.This is one of those jobs that is better left to the experts.

 

You have to take out the valves and measure the valve heads  stems and valve guides for wear. Some may need to be replaced, or the guides may need to be knurled and reamed. With the guides seen to, you can grind the valve seats and valves.

 

If you really want to do a good job you will also measure the cylinders for taper and inspect for wear and scoring. If they are within spec, no bad scoring and no more than .007 taper, take out the pistons and rods, hone the cylinders and put on new rings.

 

This is called a ring and valve job and was a common overhaul back when yours was a late model. Usually done when the engine had 30,000 to 50,000 miles on it. The engine would run like new for another 30,000 to 50,000 miles.

To gain access to the valve-spring-lifter side pans, remove right front wheel and the inside fender panel  If you're reasonably thin, after the manifolds are off, you can actually stand between the engine and the fender to better lap the valves.  I've done it in my youth, but am no longer thin enough!  :-)

Rusty,

 

After analyzing what has to be done I agree that it would be better to have it done in a shop that has the experience ,

 

Thanks for your input.

Not just the experience but the correct measuring and valve grinding tools, possible valve guide replacement etc. Hope you can find an old timer who is used to working on flathead engines.
