    Posted: 19 Jan 2010 at 6:43pm

The valve seals (and maybe valve guides) are leaking in my WD.  Gonna' replace the seals with the head still installed on the tractor tomorrow.  (I've done this on cars many times.)  Are there any secrets that are unique to the WD when doing this?
Why is there never time to do it right the first time, but always time to go back and fix it?

There are no valve seals on a WD engine unless somebody added them. If you are sucking oil through the guides, the guides probably need replaced.

Interesting! There are rubber seals directly above the surface of the head.  Due to the amount of work involved, I'm gonna' take a shot at replacing what is there.  May work or may not.  I don't know what is keeping them in place.  Will check it out tomorrow.

Osage orange usually they dont have valve seals. most just have a plate that shields the valves from oil goes right over the four bolts that hold the rocker stands and valve cover . I personally prefer the valve seals and add them to every new head I do. The reason is I have had better luck with valve springs that have some oil going to them even though most springs fall off 10 lbs on first few runs the one lubricated seam not to fall off as bad.

I'm anxious to get another look at that head.  Can't figure out what holds the seal in place unless the seal outer diameter is large enough to somehow bind on the valve spring.

I wonder if the seals someone put in are the umbrella type found on Ford V-8's from the 60's and 70's? A positive control type would clamp on the guide itself.

The seals are umbrella type, like the ones used on a Chevrolet 350 engine.

When you say umbrella type on a Chevy, do you mean the metal "Cap" that is sealed to the valve stem with an O ring?

you cut the outside diameter of the guilde down to accept the seal press fit

You could do it like this fellow did. Two has to be better than one.
Picture 067
 
Opps it didn't work! Seems it cut off the lubrication and lets the valves run dry.
Picture 068
 
Chevy didn't design the Allis engines and Allis didn't design the Chevy engines.
 
If that is where your oil is getting by it could be a short fix but it for sure will not last very long compaired to what little more time it takes in putting gin new guides.
