I am looking for a parts source for my 1957 lincoln 368. I need valve seals, valve cover gaskets, and valve cover grommets. I am pretty sure most of the parts are different than the ford y block. I am not sure. Any help would be appreciated.
I have bad blowby but have good compression all the way around. definitely broken valve seals when i pulled the valve covers. will it help to just do valve seals?
It might, I would have the heads gone through just to be on the safe side. Sent from my iPhone using The H.A.M.B. mobile app
Blowby is usually bad piston rings, are you sure you’re having blowby? Sent from my iPhone using The H.A.M.B. mobile app
Suggest looking into Ford truck/commercial/industrial parts as these were out of Heavy F-7/F-8 trucks from '52-'64 & used the same gasket sets & shared most internal parts. If it's worn enough to need the head work you've described, I'd STRONGLY suggest replacing the timing chain set, cam bearings, piston rings & oil pump, & at least inspect the rod/main bearings for wear. Yes, I know it sounds like a rebuild, but once you do, it'll be "good" for at least another 150K to 200K!
http://www.ford-y-block.com/ John Mummert has all kinds of Y Block parts including the Lincoln version.
If your leaving the heads on and removing the valve springs you can buy umbrella style seals that should fit over the tops of the guides. Just measure the guide OD and research seal ID’s and get the correct stem diameter. Chevrolet’s just had a square o-ring for years. As for the 2 rocker cover and valley cover tapered rubber bushings the Y Blocks fit GMC 6’s perfect. I’d be surprised if they didn’t work.
I like Egge for my 368 build. They are pros. Sometimes Hagen's stuff can be old. That's something you don't want in gaskets or seals. If you don't have the heads re-done with bronze guides and hardened seats you'll never know if the trouble isn't in the valve area. Makes running regular gas not an issue. Any other parts you need? I have a few. This is what I'm working on.
