Hey folks! I'm slowly working to get my F5 into operating condition. So far, with help from the forum, managed to get to a point where I have all the valves out, unstuck, and cleaned up. My question now is why do I have 2 valve guides that look different than the others. There is a rubber ring where my forefinger is but the other guides are solid. Any clues? I broke 3 guides while getting them out and need to replace em. Tanks in advance!!

I've got another valve related question to post but that's another thread.

 

Used to be that Ford only put the groove for the seal on intake guides, but nowadays all replacements come with it. Whether or not yuou want to put a seal on exhausts is a matter of some debate. Best idea I've heard is to get O-rings that fit the groove, they seal just as well but aren't as likely to attach themselves semi-permanently to the guide bores.

 

You can still get the no groove guides for the exhaust: Valve Guides [35] - $69.00 : Red's Headers, Speed Equipment For Old Fords

They will sell you the guides individually if you contact them.

 

Hey 38 -
Thanks for the clue. I'll have to check if any of the broken ones were the solid type. I kind of jumped around taking the easier guides out first and letting the stubborn ones soak. Each valve assembly is bagged and marked though. I'll have to check the types out when I get back to the shop. Thanks again.
