I have two Valves leaking oil I think the valve guides are no good does anyone know how I would be able to remove the valves and not damage them and replace the valve guides and put them back on correctly??? It's the original Flathead V6 Posted using the Full Custom H.A.M.B. App!
To make this repair you will need to remove the cylinder head and the side covers to access the valve springs and 'keepers'. Once the springs are released, withdraw the valves from the guides. I have not taken time to look in the Plymouth Shop Manual, but I am fairly certain the valve guides are replaceable. Usually the old guides are driven out with a suitable tool and a hammer. New guides are installed in similar fashion. The valve seats should be ground concentric with the new guides and the valve head faces reground. This is only a brief description of the process. I would strongly recommend you obtain a Shop Manual and follow more detailed and precise instructions. By the way, you engine is correctly described as an I-6 (I for Inline), not a V6...a common mistake in these days of many V6's. Ray
Having A service manual for your car is a must. Google Roberts Motor Parts, you can get it from him. Also the following forum is a wealth of knowledge on early mopars: p15-d24.com
Same guides for intake / exhaust. But they have a rounded end and a flatter one the go one way on intake and the other way on exhaust, but I can not rember which is which. The old time repair used to be to remove the valves and knurl the interior of the guide. The process raises a surface so that it seals better against the stem. It is a temporary fix but on a limited use vehicle could postpone the replacement job by three or four years.
Knurling will work just fine on a sidevalve engine.Oil doesnt run uphill very well.You will have to find a knurling tool the right size-I went to the snap off guy and tried to buy a 3\8 knurling tool to replace the one from my (40 YO) set and they no longer have them!! I reckon I am getting old----
